ITEM 1.    BUSINESS

GENERAL

         USA Truck, Inc. (the "Company" or "USA Truck") is engaged in the
transportation of general commodity freight in interstate and foreign commerce.
Operations are conducted primarily east of the Rocky Mountains, but the Company
holds authority to transport and does transport freight between all points in
the continental United States, other than intrastate, and between all points in
the U.S., on the one hand, and the Canadian provinces of Ontario and Quebec, on
the other. The principal types of freight transported include automotive parts
and materials, tires, paper and paper products, glass, retail store merchandise,
chemicals, aluminum and manufacturing materials and supplies. USA Truck does not
transport Class A or Class B explosives, garbage, radioactive materials or
hazardous wastes. The Company does not operate any flatbed, tanker or other
specialized trailers.

         USA Truck transports freight in truckload quantities from individual
shippers to single or multiple destinations on an as-needed basis. Its business
consists primarily of medium haul shipments, more than 700 but less than 1,000
miles. For 1995, 1996 and 1997, the average length of haul for Company tractors
was 900 miles, 878 miles and 920 miles, respectively.

         The Company was incorporated in 1983 as a wholly-owned subsidiary of
Arkansas Best Corporation. In December 1988, the stock of the Company was sold
to management, and the Company completed its initial public offering of Common
Stock in late March 1992.

         The Company's principal offices are located at 3108 Industrial Park
Road, Van Buren, Arkansas 72956, and its telephone number is (501) 471-2500.

BUSINESS STRATEGY

         USA Truck's principal competitive strength is its ability and
commitment to consistently provide superior service to shippers. Although price
is a primary concern to all shippers, many of the Company's customers are
high-volume shippers that require a flexible and dependable source of motor
carrier service tailored to specific needs, including pickup or delivery within
narrow time windows. The Company's strategy is to provide a premium service to
meet these needs and to charge compensating rates for such service. This
approach has found increasing acceptance. See "Business -- Competition".

         The Company is committed to prompt freight pickup, consistent on-time
delivery and twenty-four hours a day, seven days a week dispatching. It has
taken a number of steps to meet these commitments. In particular, it (i) uses
only its own tractors and trailers, rather than owner-operators, to provide
greater flexibility and control over quality of service, better work performance
from drivers and better insurance rates; (ii) adheres to strict maintenance and
cleaning schedules to avoid breakdowns and delays; (iii) provides detailed
routing instructions for, and maintains satellite communications with, drivers
to expedite delivery; (iv) maintains trailer pools at strategic locations to
minimize the time between customer order and pickup; and (v) provides extra
trailers to high volume shippers for loading and unloading at their convenience.

         USA Truck utilizes cost-efficient communications throughout its
operations. The Company has EDI (electronic data interchange) arrangements with
several of its largest customers, providing them with access through their
computer systems to current information on the status of their shipments.
Beginning in the third quarter of 1997, the Company began installing two-way,
satellite based mobile messaging and position-locating equipment in all of its
tractors. This equipment is designed to fulfill customers' heightened need for
real time transit information as well as provide the Company with an enhanced
and cost-effective method of communications between its drivers and its
operations personnel. The system permits fleet managers to contact drivers
virtually anywhere in the Company's market area. These capabilities are intended
to shorten response time to customers, as well as to allow drivers rest time
while awaiting assignment. The installation of the equipment was completed in
the fourth quarter of 1997.


                                       1
<PAGE>   4


         The Company has designed its own management information software
systems, which it operates on a mainframe computer that the Company acquired
during 1997. This system became operational during the second quarter of 1997,
when the Company's software was migrated to the new computer. Prior to that, the
Company was on-line with a mainframe computer through a contractual agreement
with a third party. These data processing capabilities enhance operating
efficiency by providing immediate access to detailed information concerning
equipment, cargo, customer's location, credit history, billing arrangements and
specific customer requirements. They also permit the Company to respond quickly
and accurately to customers' requests and assist in balancing equipment
availability throughout the market area. Management believes these information
software systems and computer hardware will be sufficient to support the
Company's expansion plans at least through 1999 without substantial additional
expenditures in the data processing area.

MARKETING AND SALES

         The Company focuses its marketing efforts on customers with demanding
requirements and heavy shipping needs within the regions where the Company
operates. This permits the Company to concentrate available equipment in its
primary service area, enabling it to be more responsive to customer needs. USA
Truck's Marketing and Operations Departments have primary responsibility for
developing and implementing the Company's marketing strategy and retaining
customer accounts.

         The Marketing Department solicits and responds to customer orders and
maintains close customer contact regarding service requirements and rates. A
high percentage of the Company's business is from repeat customers. For the year
ended December 31, 1997, at least 95% of USA Truck's operating revenues was
derived from customers that were customers of the Company prior to 1997.

         USA Truck establishes rates through individual negotiations with
customers and through contracts tailored to the specific needs of shippers.

         For the year ended December 31, 1997, the Company's ten largest
customers accounted for 44.3% of revenues and its three largest customers
accounted for 25.8% of revenues, with more than 1,050 other customers accounting
for the balance. One customer, Wal-Mart Stores, Inc., accounted for 12.6% of
revenues for the year.
No other customer accounted for more than 10% of revenues.

         Customers are generally required to have credit approval before
dispatch. The Company bills customers at or shortly after pickup, and for the
last three years receivables collection has averaged approximately 31 days from
the billing date.

OPERATIONS

         The Operations Department consists of two divisions: the Load
Coordinator Group and the Fleet Manager Group.

         Load coordinators are responsible for efficiently matching available
equipment with customer needs, and they serve as the contact with customers'
receiving and shipping personnel. Load coordinators also have primary
responsibility for minimizing empty miles, and they work closely with the
Marketing Department to increase equipment utilization.

         The average distance between loads as a percentage of total miles
(empty mile factor) is a standard measurement in the truckload industry. The
empty mile factor generally decreases as average length of haul and density of
trucks in an area increase. The Company's commitment to on-time pickup often
requires a tractor to travel farther to complete a pickup than it would have to
travel if the Company delayed the pickup until a tractor became available in the
area. USA Truck's empty mile factor was 10.05% for the year ended December 31,
1997.

         Fleet managers supervise fleets of approximately 48 drivers each and
serve as the drivers' primary contacts with the Company. Fleet managers monitor
the location of equipment and direct its movement in the most efficient and safe
manner practicable.

DRIVERS AND OTHER PERSONNEL

         Driver recruitment and retention continue to be difficult. Recruitment
is difficult because Company standards are high and because of declining
enrollment in driving schools. Retention is difficult because of wage and job
fulfillment considerations. Driver turnover, especially in the early months of
employment, is a significant problem, and the competition for qualified drivers
is intense. Although USA Truck has experienced difficulty with driver turnover,
it has been able to attract and retain qualified drivers sufficient to support
its operations. To attract and retain drivers, the Company must continue to
provide safe, attractive and comfortable equipment, direct access to management,
and competitive wages, benefits and financial incentives designed to encourage
longer term employment.

         Drivers' pay is calculated on the basis of miles driven and increases
with tenure. In 1997, drivers averaged 502 miles per work day. Drivers are also
paid bonuses based on productivity and tenure. For 1997, the Company's drivers
earned bonuses totaling approximately $1,203,000. During 1997, the Company's
drivers earned wages and bonuses averaging $.29 per mile.

         At December 31, 1997, USA Truck employed 1,304 persons, of which 962
were drivers, none of whom was represented by a collective bargaining unit. In
the opinion of management, the Company's relationship with its employees is
satisfactory.

SAFETY

         USA Truck's safety program is designed to create an accident-free
working environment and to enforce governmental safety regulations. The Company
controls the maximum speed of its tractors with electronic governing equipment,
and all its tractors are equipped with anti-lock braking systems. The Company
has received a number of awards based on its safety record, including the 1996
Fleet Safety Award for large carriers, awarded by the Truckload Carriers
Association.

         Safety records are one of several hiring criteria used by USA Truck,
and safe equipment handling techniques are an important part of new driver
training. The Company also conducts pre-employment, random and post-accident
drug testing in accordance with Department of Transportation ("DOT")
regulations.

REVENUE EQUIPMENT AND MAINTENANCE

         The Company's current policy is to replace most tractors within 42
months from the date of purchase, which permits the Company to maintain
substantial warranty coverage throughout the period of ownership. USA Truck
replaces its tractors and trailers based on various factors, including the used
equipment market, prevailing interest rates, technological improvements, fuel
efficiency and durability. The following table shows the number of units and age
of revenue equipment operated by the Company at December 31, 1997:

</TABLE>

         At December 31, 1997, USA Truck operated 1,007 conventional sleeper
tractors and 1,928 van trailers. To simplify driver and mechanic training,
control the cost of spare parts and tire inventory and provide for a more
efficient vehicle maintenance program, the Company buys tractors and trailers
manufactured to its specifications. In



                                       3
<PAGE>   6

deciding which equipment to buy, it considers a number of factors, including
safety, economy, resale value and driver comfort. All of the Company's tractors
are equipped with Detroit Diesel Series 60 engines, air-ride suspension and
anti-lock brakes. The Company's equipment is maintained through a strict
preventive maintenance program designed to minimize equipment downtime and to
enhance trade-in value.

         Beginning with the November 1995 trailer purchases, the Company began
converting its trailer fleet from 48-foot long and 102 inches wide trailers to
53-foot long and 102 inches wide trailers. Because of this conversion process,
the Company's trailer to tractor ratio was 1.9-to-1 at December 31, 1997 and
will probably increase until the conversion process is substantially completed,
before returning to its historical 1.7-to-1 ratio. Management believes the
1.7-to-1 ratio is ideal for the Company's operations, in that it promotes
efficiency and provides the flexibility needed to serve customer needs. As of
December 31, 1997, 811 of the 1,928 trailers in the Company's trailer fleet were
53-foot models. All future purchases of trailers will be 53-foot models. The
Company is undertaking this conversion in order to meet its customers'
requirements and to continue to provide an efficient balance between trailer
capacity and weight and length limitations in the various states and Canada.

         During 1997 the Company financed revenue equipment through its
collateralized, $28.5 million revolving credit agreement (the "General Line of
Credit" or "Line of Credit"), through conventional financing and lease-purchase
arrangements. See "Item 7. Management's Discussion and Analysis of Financial
Condition and Results of Operations--Liquidity and Capital Resources". All of
its revenue equipment is pledged to secure its obligations under such financing
arrangements.

REVENUE EQUIPMENT ACQUISITION PROGRAM

         During 1998 and 1999, the Company plans to acquire 460 and 336 new
tractors and 210 and 500 new trailers, respectively. This will result in net
increases of 172 and 177 tractors and 111 and 266 trailers, respectively. As of
February 27, 1998, contracts had been executed for the acquisition of all 460
tractors and 210 trailers to be acquired in 1998 and 336 tractors to be acquired
in 1999. Although these contracts fix the price at which the Company may acquire
this equipment, the Company has the right in its discretion to decrease or
increase the number of tractors or trailers to be purchased during the year at
agreed prices. See "Item 7. Management's Discussion and Analysis of Financial
Condition and Results of Operations--Liquidity and Capital Resources".

         During 1997, the Company acquired 416 new tractors (a net increase of
146) and 505 new trailers (a net increase of 419). The Company purchased more
new tractors and trailers in 1997 than anticipated, in response to current
economic conditions and strong demand in the truckload industry.

INSURANCE

The primary risk areas in the motor carrier industry are cargo loss and damage,
personal injury, property damage and workers' compensation claims. Management
believes that its insurance coverages are sufficient in each of these areas. It
is qualified as a workers' compensation self-insurer in the States of Arkansas
and Louisiana. The workers' compensation self-insurance is secured by $300,000
in certificates of deposit. In June 1993, the Company received authority to
self-insure for cargo loss and damage claims and up to $1.0 million per
occurrence for bodily injury and property damage ("BIPD") claims. These
self-insurance arrangements are secured by $1.01 million in letters of credit
with the Federal Highway Administration. During 1997, the self-insurance
retention levels were $1.0 million for BIPD and $500,000 for workers'
compensation claims per occurrence. The Company has insurance coverage for cargo
loss and damage claims exceeding $100,000 per occurrence and coverage for
physical damage to its tractors and trailers with a self insurance level of
$10,000 per occurrence. The Company has excess general liability coverage in
amounts substantially exceeding minimum legal requirements and believed to be
sufficient to protect the Company against material loss.

FUEL AVAILABILITY AND COST

         The motor carrier industry is dependent upon the availability of diesel
fuel, and fuel shortages or increases in fuel taxes or fuel costs have adversely
affected, and may in the future adversely affect the profitability of USA Truck.
Fuel prices have fluctuated widely and fuel taxes have generally increased in
recent years. The Company has not experienced difficulty in maintaining
necessary fuel supplies, and in the past the Company generally has been able to
recover increases in fuel costs and fuel taxes from customers through increased
freight rates, though it was not able to fully offset certain significant
increases in fuel costs during 1995 and 1996. There can be no assurance that the
Company will be able to recover any future increases in fuel costs and fuel
taxes through increased rates.

COMPETITION

         The trucking industry is highly competitive. It is characterized by
ease of entry and by many small carriers having revenues of less than $1 million
per year, with relatively few carriers being able to achieve revenues exceeding
$100 million per year. The principal means of competition in the truckload
segment of the industry are service and price, with rate discounting being
particularly intense during economic downturns. Although the Company competes
primarily on the basis of service rather than rates, rate discounting continues
to be a factor in obtaining and retaining business. Although the number of firms
competing in the truckload segment has increased dramatically since industry
deregulation in 1980, the industry appears to be undergoing a consolidation
phase. Furthermore, a depressed economy tends to increase both price and service
competition from alternative modes such as less-than-truckload carriers and
railroads. Management believes that further growth in the truckload segment of
the industry is likely to be achieved through a shift in market shares among
competitors rather than through an increase in the size of the market.

         USA Truck competes primarily with other truckload carriers and
shipper-owned fleets and, to a lesser extent, with railroads and
less-than-truckload carriers. A number of truckload carriers have much greater
financial resources, own more revenue equipment and carry a larger volume of
freight than does the Company.

         The Company also competes with truckload and less-than-truckload
carriers for qualified drivers. See "Business -- Drivers and Other Personnel".

TRADEMARK

         The Company's name and logo are registered with the United States
Patent And Trademark Office and the Canadian Trade Marks Office. The Company
believes that its trademark has significant value and is important to its
marketing efforts.

REGULATION

         USA Truck is a motor carrier regulated by the DOT and other federal and
state agencies. The Company's business activities in the United States are
subject to broad federal, state and local laws and regulations beyond those
applicable to most business activities. These regulated business activities
include, among other things, service area, routes traveled, equipment
specifications, commodities transported, rates and charges, accounting systems,
financial reporting and insurance coverages. The Company's Canadian business
activities are subject to similar requirements imposed by the laws and
regulations of the Dominion of Canada and provincial laws and regulations.

         Motor carrier operations are subject to safety requirements prescribed
by the DOT, governing interstate operation, and by Canadian provincial
authorities. Matters such as weight and equipment dimensions are also subject to
federal, state and provincial regulations.

         The Company is subject to federal, state, provincial and local
environmental laws and regulations. Management believes that the Company is in
substantial compliance with such laws and regulations and that costs of such
compliance will not have a material adverse effect on its competitive position,
operations or financial condition or require a material increase in currently
anticipated capital expenditures.

ITEM 2.       PROPERTIES

         The Company owns its headquarters in Van Buren, Arkansas, located on 63
acres, of which 23 acres were acquired in 1997. This site has approximately
84,000-square feet of office, training and driver housing space within two
structures, a 12,000-square foot maintenance facility and a 2,500-square foot
dock. In the second quarter of 1997, the Company completed construction of a new
57,000-square foot corporate headquarters next to its existing headquarters
facility in Van Buren, Arkansas. The previously existing 27,000-square foot
facility will be refurbished over the next several years to house additional
training, maintenance and support services. This facility also contains
above-ground fuel tanks with a capacity of 40,000 gallons.

         The Company operates a maintenance and driver facility in West Memphis,
Arkansas, situated on roughly 16 acres with 13 acres of paved tractor and
trailer parking behind fence, a 10,000-square foot shop, a four-lane drive
through fueling station containing above ground fuel tanks with a capacity of
37,000 gallons and drivers' sleeping quarters that can house 36 drivers. The
drivers' quarters also include a recruiting office and driver training center
for new drivers. The Company owns 13 of the 16 acres and leases the remainder
under a long-term lease agreement with an initial term ending in November 2044.
Located at the intersection of I-40 and I-55, this facility is an ideal location
for these activities.

         In August 1995, the Company began operating its maintenance and driver
facility in Shreveport, Louisiana, with 15 acres of paved tractor and trailer
parking behind fence, a 12,000-square foot shop, a two-lane drive through
fueling station containing above ground fuel tanks with a capacity of 37,000
gallons and a drivers' sleeping quarters that can house 32 drivers. The drivers'
quarters also include a recruiting office and driver training center for new
drivers. The facility is located on 20 acres of land owned by the Company near
I-20 on US Hwy. 80 and is strategically located near several major customers in
the area.

         In June 1996 the Company began operating its maintenance and driver
facility in Vandalia, Ohio, with 4 acres of paved tractor and trailer parking
behind fence, a 2,400-square foot shop, a one-lane drive through fueling station
containing a below ground fuel tank with a capacity of 10,000 gallons and a
drivers' sleeping quarters that can house 22 drivers. The drivers' quarters also
include a sales office. The facility is located on approximately 5 acres of land
owned by the Company near I-75 & US Hwy. 40 and is strategically located for
these activities.

         The Company leases, on a month-to-month basis, parking and office
facilities in East Peoria and Blue Island, Illinois.

         Management believes that its facilities will be sufficient for its
operations at least through 1998.

         See "Item 1. Business -- Revenue Equipment and Maintenance" and "Item
1. Business -- Revenue Equipment Acquisition Program" for information regarding
the Company's revenue equipment.

ITEM 3.           LEGAL PROCEEDINGS

         The Company is a party to routine litigation incidental to its
business, primarily involving claims for personal injury and property damage
incurred in the transportation of freight. It maintains insurance covering
liabilities resulting from personal injury and property damage claims.
Management believes that adverse results in one or more of these cases would not
have a material adverse effect on the financial position of the Company.


ITEM 4.           SUBMISSION OF MATTERS TO A VOTE OF SECURITY HOLDERS

         The Company did not submit any matter to a vote of security holders
during the fourth quarter of the fiscal year covered by this Annual Report.

</TABLE>


         As of February 27, 1998, there were 315 holders of record (including
brokerage firms and other nominees) of the Company's Common Stock. The Company
estimates that there were approximately 2,175 beneficial owners of the Common
Stock as of that date.

         The Company has never paid a cash dividend on its Common Stock. It is
the current intention of the Company's Board of Directors to continue to retain
earnings to finance the growth of the Company rather than to pay cash dividends.
Any future payments of cash dividends will depend upon the financial condition,
results of operations and capital commitments of the Company as well as other
factors deemed relevant by the Board of Directors. Covenants contained in the
Company's General Line of Credit may limit the Company's ability to pay
dividends.

RESULTS OF OPERATIONS

Year Ended December 31, 1997 Compared to Year Ended December 31, 1996

         Operating revenues increased 19.6% to $129.5 million in 1997 from
$108.3 million in 1996, resulting from increased business with existing
customers and additional business from new customers. Average revenue per mile
remained unchanged at $1.11 in both 1997 and 1996. The empty mile factor
decreased to 10.05% in 1997 from 10.16% of paid miles in 1996. There was a 14.0%
increase in the number of shipments to 114,022 in 1997 from 99,979 in 1996. This
volume improvement was made possible by an increase of 16.6% in the average
number of tractors operated from 802 in 1996 to 935 in 1997. The net effect of
the volume improvement and the Company's continuing fleet expansion was an
increase of 2.8% in miles per tractor per week to 2,475 in 1997 from 2,407 in
1996.

         Operating expenses and costs as a percentage of revenues improved to
89.1% in 1997 from 94.2% in 1996. This change resulted primarily from a
decrease, on a percentage of revenue basis, in salaries, wages and employee
benefits expenses, in operations and maintenance costs, in insurance and claims
expenses, in depreciation and amortization expense and in other expenses.
Salaries, wages and employee benefits decreased, relative to revenues, primarily
from favorable experience in employee health benefits. The percentage decrease,
relative to revenues, in operations and maintenance was primarily the result of
a decrease of 2.2 cents per gallon in the average cost of fuel in 1997 compared
to 1996, and of an increase in fuel efficiency to 6.29 average miles per gallon
in 1997 from 6.12 in 1996. The percentage decrease, relative to revenues, in
insurance and claims expenses was due to a decrease in the number and severity
of accidents in 1997 as compared to last year. The overall net cost of those
accidents incurred was reduced by insurance coverage for physical damage to
tractors and trailers with a self insurance level of $10,000 per occurrence,
effective January 1, 1997. The decrease in depreciation and amortization
expense, as a percentage of revenue, reflects the 2.8% increase in utilization
as mentioned above. Other expenses decreased, in both dollars and relative to
revenues, due to a variety of factors, no single one of which accounted for more
than half of the decrease.

         As a result of the foregoing factors, operating income increased 126.6%
to $14.2 million, or 10.9% of revenues, in 1997 from $6.3 million, or 5.8% of
revenues, in 1996.

         Interest expense increased 89.0% to $1.4 million in 1997 from $730,000
in 1996, resulting primarily from an increase in borrowings to facilitate
equipment purchases, partially offset by a decrease in interest rates, in the
aggregate, on both short-term and long-term debt.

         Other income, net, increased, both in dollar amount and on a percentage
of revenue basis, from $4,000 in 1996 to $191,000 in 1997. This was due to a
variety of factors, no single one of which accounted for more than half of the
increase.

         As a result of the above, income before income taxes increased 134.5%
to $13.0 million, or 10.0% of revenues, in 1997 from $5.5 million, or 5.1% of
revenues, in 1996.

         The Company's effective tax rate increased to 39.1% in 1997 from 38.9%
in 1996. The effective rates varied from the statutory Federal tax rate of 34%
primarily due to state income taxes and certain non-deductible expenses.

         As a result of the aforementioned factors, net income increased 133.7%
to $7.9 million, or 6.1% of revenues, in 1997 from $3.4 million, or 3.1% of
revenues, in 1996, a increase of 137.1% in diluted net income per share to $.83
from $.35. The number of shares used in the calculation of diluted net income
per share for 1997 and 1996 were 9,484,570 and 9,619,919, respectively.

Year Ended December 31, 1996 Compared to Year Ended December 31, 1995

         Operating revenues increased 5.8% to $108.3 million in 1996 from $102.4
million in 1995, resulting from increased business with existing customers and
additional business from new customers. Average revenue per mile remained
unchanged at $1.11 in both 1996 and 1995. The empty mile factor decreased to
10.16% in 1996 from 10.69% of paid miles in 1995. There was a 9.3% increase in
the number of shipments to 99,979 in 1996 from 91,460 in 1995. This volume
improvement was made possible by an increase of 4.0% in the average number of
tractors operated from 771 in 1995 to 802 in 1996. The net effect of the volume
improvement and the Company's continuing fleet expansion was an increase of 1.0%
in miles per tractor per week to 2,407 in 1996 from 2,382 in 1995.

         Operating expenses and costs as a percentage of revenues increased to
94.2% in 1996 from 89.8% in 1995. This change resulted primarily from an
increase, on a percentage of revenue basis, in operations and maintenance costs,
in insurance and claims expenses, in communications and utilities and in other
expenses. These increases were partially offset by decreases, on a percentage of
revenue basis, in salaries, wages, and employee benefits. The decreases in
salaries, wages, and employee benefits were due to the fact that the increase in
aggregate driver pay was offset by a decrease in incentives earned by employees
due to a decrease in the operational and financial performance of the Company.
The percentage increase, relative to revenues, in operations and maintenance was
primarily the result of an increase of 12.1 cents per gallon in the average cost
of fuel in 1996 year compared to the prior year, partially offset by an increase
in fuel efficiency to 6.12 average miles per gallon in 1996 from 6.08 in 1995.
The percentage increase, relative to revenues, in insurance and claims expense
was due to an increase in the number and severity of accidents in 1996 as
compared to prior year. The number and severity of accidents decreased in the
second half of the year as driver retention improved from the unusually low
levels the Company experienced in the first half of 1996. Communications and
utilities increased, on a percentage of revenue basis, due to the aggregate
effect of a slight increase in service costs and the expiration of usage
incentives that were available in the telecommunications industry in 1995. Other
expenses increased, relative to revenues, due to a variety of factors, no single
one of which accounted for more than half of the increase. One such factor was
an increase of approximately $389,000 in information system programming and
processing costs.

         As a result of the foregoing factors, operating income decreased 40.1%
to $6.3 million, or 5.8% of revenues, in 1996 from $10.4 million, or 10.2% of
revenues, in 1995.

         Interest expense decreased 8.6% to $730,000 in 1996 from $799,000 in
1995, resulting primarily from a decrease in interest rates, in the aggregate,
on both short-term and long-term debt.


                                       10
<PAGE>   13


         Other expenses, net, remained unchanged, on a percentage of revenue
basis, between 1996 and 1995. This was due to the fact that the decrease in
interest expense was offset by the decrease in interest income and gains on
disposal of assets.

         As a result of the above, income before income taxes decreased 43.5% to
$5.5 million, or 5.1% of revenues, in 1996 from $9.8 million, or 9.6% of
revenues, in 1995.

         The Company's effective tax rate increased to 38.9% in 1996 from 38.4%
in 1995. The effective rates varied from the statutory Federal tax rate of 34%
primarily due to state income taxes and certain non-deductible expenses.

         As a result of the aforementioned factors, net income decreased 44.0%
to $3.4 million, or 3.1% of revenues, in 1996 from $6.0 million, or 5.9% of
revenues, in 1995, a decrease of 41.7% in diluted net income per share to $.35
from $.60. The number of shares used in the calculation of diluted net income
per share for 1996 and 1995 were 9,619,919 and 10,028,478, respectively.

INFLATION

         The effect of inflation on operating costs has been minimal in recent
years. Most of the Company's operating expenses are inflation sensitive, with
increases in inflation generally resulting in increased operating costs and
expenses. The effect of inflation-driven cost increases on the Company's overall
operating costs would not be expected to be greater for the Company than for its
competitors.

SEASONALITY

         In the trucking industry generally, revenues decrease as customers
reduce shipments during the winter holiday season and as inclement weather
impedes operations. At the same time, operating expenses increase, due primarily
to decreased fuel efficiency and increased maintenance costs. Future revenues
could be impacted if customers reduce shipments due to temporary plant closings,
which historically have occurred during July and December.

FUEL AVAILABILITY AND COST

         The motor carrier industry is dependent upon the availability of diesel
fuel, and fuel shortages or increases in fuel taxes or fuel costs have adversely
affected, and may in the future adversely affect the profitability of USA Truck.
Fuel prices have fluctuated widely and fuel taxes have generally increased in
recent years. The Company has not experienced difficulty in maintaining
necessary fuel supplies, and in the past the Company generally has been able to
recover increases in fuel costs and fuel taxes from customers through increased
freight rates, though it was not able to fully offset certain significant
increases in fuel costs during 1995 and 1996. There can be no assurance that the
Company will be able to recover any future increases in fuel costs and fuel
taxes through increased rates.

LIQUIDITY AND CAPITAL RESOURCES

         The continued growth of the Company's business has required significant
investments in new revenue equipment. USA Truck has financed revenue equipment
purchases with cash flows from operations and through borrowings, including
borrowings under the General Line of Credit, and capitalized lease obligations.
Working capital needs have generally been met with cash flows from operations
and occasionally with borrowings under the General Line of Credit. Although the
Company has not relied significantly on the General Line of Credit to meet
working capital requirements, it does experience cyclical cash flow needs common
to the industry. The Company uses the General Line of Credit to minimize these
fluctuations and to provide flexibility in financing revenue equipment. Cash
flows from operations were $28.3 million for 1997 and $14.9 million for 1996.

         The Company's General Line of Credit provides for available borrowings
of up to $28.5 million, including letters of credit not exceeding $5.0 million.
As of December 31, 1997, approximately $16.0 million was available under the
General Line of Credit. The General Line of Credit matures on April 30, 2000,
prior to which time, subject to certain conditions, the amount outstanding can
be converted at any time, at the Company's option, to a four-year term loan
requiring 48 equal monthly principal payments plus interest. The interest rate
on the General Line of Credit (8.50% at December 31, 1997) fluctuates between
the lender's prime rate or prime plus 1/2% or LIBOR, depending upon the ratio of
the Company's debt to tangible net worth. Under the General Line of Credit, the
Company has the right to borrow at a rate related to the Eurodollar rate when
this rate is less than the lender's prime rate. A quarterly commitment fee of
1/4% per annum is payable on the unused amount. The principal maturity can be
accelerated if the borrowing base (based on percentages of receivables and
otherwise unsecured equipment) does not support the principal balance
outstanding. The General Line of Credit is collateralized by accounts receivable
and all otherwise unencumbered equipment. The Company has the option under
certain conditions and at certain rates to fix the rate and term on portions of
the outstanding balance of the General Line of Credit. See Note 4 to the
Financial Statements.

         On November 19, 1997 the Company entered into a lease commitment
agreement (the "Equipment TRAC Lease Commitment"), with another financial
institution to facilitate the leasing of tractors. The Equipment TRAC Lease
Commitment has a commitment term ending on December 31, 1998 and provides for a
maximum borrowing amount of $12.6 million. Each capital lease will have a
repayment period of 42 months. Borrowings are limited based on the amounts
outstanding under capital leases entered into under this agreement. As of
December 31, 1997 $12.6 million remained available under the Equipment TRAC
Lease Commitment. The interest rate on the capital leases under the Equipment
TRAC Lease Commitment fluctuates in relation to the interest rate for
3 1/2-year Treasury Notes as published in The Wall Street Journal and is fixed
upon execution of a lease.

         On November 13, 1996 the Company amended its lease commitment agreement
(the "TRAC Lease Commitment"), dated January 24, 1996, to extend the term and
increase the borrowing limit to an amount equal to the sum of the current
outstanding balance plus $10.0 million, resulting in a new lease commitment with
a maximum aggregate borrowing amount of $16.0 million. The TRAC Lease Commitment
facilitates the leasing of tractors. The commitment term ended on December 31,
1997. Each capital lease has a repayment period of 42 months. The interest rate
on the capital leases under the TRAC Lease Commitment fluctuates in relation to
the weekly average interest rate for 2-year Constant Maturity Treasury
Securities as published by the Federal Reserve and is fixed upon execution of
lease. As of December 31, 1997, capital leases in the aggregate principal amount
of $14.7 million were outstanding under the TRAC Lease Commitment.

         The Company's long-term debt, excluding current portion, increased by
70.5% to $27.1 million at December 31, 1997 from $15.9 million at December 31,
1996. This increase was primarily the result of borrowings under the TRAC Lease
Commitment and the General Line of Credit for revenue equipment purchases and
the repurchase of common stock of the Company.

         During the years 1998 and 1999, the Company plans to make approximately
$68.8 million in capital expenditures. At December 31, 1997, USA Truck was
committed to spend $34.7 million of this amount for revenue equipment in 1998,
and $31.5 million of this amount is currently budgeted for revenue equipment in
1999. The commitments to purchase revenue equipment are cancelable by the
Company if certain conditions are met. The balance of the expected capital
expenditures will be used for maintenance and office equipment and facility
improvements.


                                       12

         The General Line of Credit, the Equipment TRAC Lease Commitment,
equipment leases and cash flows from operations should be adequate to fund the
Company's operations and expansion plans through the end of 1998. There can be
no assurance, however, that such sources will be sufficient to fund Company
operations and all expansion plans through such date, or that any necessary
additional financing will be available, if at all, in amounts required or on
terms satisfactory to the Company. The Company expects to continue to fund its
operations with cash flows from operations, equipment leases, the General Line
of Credit, and the Equipment TRAC Lease Commitment for the foreseeable future.

         In September 1995, the Board of Directors authorized the Company to
repurchase up to 500,000 shares of its outstanding common stock, on the open
market or in privately negotiated transactions, from time to time over a period
of three years. As of February 27, 1998, the Company had purchased 440,500
shares pursuant to this authorization at an aggregate purchase price of $4.4
million, including 40,500 shares purchased in 1997 at an aggregate purchase
price of $329,000. On May 7, 1997, the Board of Directors authorized the
retirement of all shares purchased prior to May 6, 1997, which resulted in the
retirement of 185,500 shares of treasury stock that had been purchased at an
aggregate cost of $1.6 million. The Company had previously retired 254,000
shares of treasury stock on May 8, 1996. In addition, 672 of the remaining 1,000
repurchased shares have been resold under the Company's Employee Stock Purchase
Plan (the "Plan"). The Company may continue to purchase shares in the future for
purposes of the Plan, or otherwise if, in the view of management, the common
stock is undervalued relative to the Company's performance and prospects for
continued growth. Any such purchases would be funded with cash flows from
operations or the General Line of Credit.

YEAR 2000 ISSUES

         The Company believes that the computer equipment and software used by
the Company will function properly with respect to dates in the Year 2000 and
thereafter. The Company has reviewed its computer systems, using both internal
and external resources, and has made and continues to make certain modifications
to address Year 2000 issues. The Company is in the process of communicating with
its significant suppliers and customers to determine the extent to which
interfaces with such entities are vulnerable to Year 2000 issues and the extent
to which any products purchased from such entities are vulnerable to Year 2000
issues. The Company presently believes that the Year 2000 issues will not
require the Company to incur any material cost or pose significant operational
problems for the Company directly or as a result of any Year 2000 issue of
suppliers or customers.

NEW ACCOUNTING PRONOUNCEMENTS

         In 1997, the Financial Accounting Standards Board issued Statement No.
128, Earnings per Share (SFAS 128). The standard replaced the calculation of
primary and fully diluted earnings per share with basic and diluted earnings per
share. Unlike primary earnings per share, basic earnings per share excludes any
dilutive effects of options, warrants and convertible securities. Diluted
earnings per share is very similar to the previously reported fully diluted
earnings per share. All earnings per share amounts for all periods in this
Annual Report have been presented, and where appropriate, restated to conform to
the SFAS 128 requirements.

         In 1997, the Financial Accounting Standards Board issued Statement of
Financial Accounting Standards No. 130, Reporting Comprehensive Income (SFAS No.
130). The provisions of SFAS No. 130 require companies to classify items of
comprehensive income by their nature in a financial statement and display the
accumulated balance of other comprehensive income separately from retained
earnings and additional paid-in capital in the financial statements. The
Company's comprehensive income items are not material; accordingly, the effect
of adopting this statement will not be material when it becomes effective for
fiscal 1998.

FORWARD-LOOKING STATEMENTS

         This report contains forward-looking statements and information that
are based on management's belief as well as assumptions made by, and information
currently available to management. Although the Company believes that the
expectations reflected in such forward-looking statements are reasonable, it can
give no assurance that such expectations will be realized. Should one or more of
the risks or uncertainties underlying such expectations materialize, or should
underlying assumptions prove incorrect, actual results may vary materially from
those expected. Among the key factors that are not within the Company's control
and that may have a direct bearing on operating results are increases in diesel
prices, adverse weather conditions or driver turnover and the impact of
increased rate competition or competition for qualified drivers. The Company's
results may also be significantly affected by fluctuations in general economic
conditions, as the Company's utilization rates are directly related to business
levels of shippers in a variety of industries. Results for any specific period
could also be affected by various unforeseen events, such as unusual levels of
equipment failure or accident claims.

                          NOTES TO FINANCIAL STATEMENTS

                                DECEMBER 31, 1997

1.  SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

DESCRIPTION OF BUSINESS

USA Truck, Inc. (the "Company"), operates as a truckload motor carrier with
operating authority to provide service throughout the continental United States
and parts of Canada and Mexico.

USE OF ESTIMATES

The preparation of financial statements in conformity with generally accepted
accounting principles requires management to make estimates and assumptions that
affect the amounts reported in the financial statements and accompanying notes.
Actual results could differ from those estimates.

CASH EQUIVALENTS

The Company considers all highly liquid investments with a maturity of three
months or less when purchased to be cash equivalents. The carrying amount
reported in the balance sheet for cash and cash equivalents approximates its
fair value.

CONCENTRATION OF CREDIT RISK

The Company performs ongoing credit evaluations and generally does not require
collateral. The Company maintains reserves for potential credit losses. Such
losses have been within management's expectations.

One customer represented approximately 11% and 10% of net trade receivables as
of December 31, 1997 and 1996, respectively. A different customer represented
13% of revenues for the year ended December 31, 1997.

INVENTORIES

Inventories consist primarily of tires, fuel and supplies and are stated at the
lower of cost (first-in, first-out basis) or market.

PROPERTY AND EQUIPMENT

Property and equipment is recorded at cost. For financial reporting purposes,
the cost of such property is depreciated principally by the straight-line method
using the following estimated useful lives: structures - 5 to 39.5 years;
revenue equipment - 3 to 7 years; and service, office and other equipment - 3 to
20 years. Gains and losses on asset sales are reflected in the year of disposal.
Trade-in allowances in excess of book value of revenue equipment are accounted
for by adjusting the cost of assets acquired. Tires purchased with revenue
equipment are capitalized as a part of the cost of such equipment, with
replacement tires being inventoried and expensed when placed in service.

                    NOTES TO FINANCIAL STATEMENTS (CONTINUED)

1.  SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (CONTINUED)

CLAIMS LIABILITIES

The Company is self-insured up to certain limits for bodily injury, property
damage, workers' compensation, and cargo loss and damage claims. Provisions are
made for both the estimated liabilities for known claims as incurred and
estimates for those incurred but not reported. In 1997 the Company was
self-insured up to $1,000,000 per occurrence for bodily injury, property damage
and $500,000 for workers' compensation claims, and up to $100,000 per occurrence
for cargo loss and damage claims. These self-insurance arrangements are secured
by $1,010,000 in letters of credit.

The workers' compensation self-insurance is secured by $300,000 in certificates
of deposit maturing during 1998. The certificates of deposit are included in
other assets on the balance sheet as of December 31, 1997 and 1996.

REVENUE RECOGNITION

Revenues are recognized based on a method whereby revenue is allocated between
reporting periods based on relative transit time in each period and direct
expenses are allocated on the same basis.

INCOME TAXES

Deferred income taxes reflect the net tax effects of temporary differences
between the carrying amounts of assets and liabilities for financial reporting
purposes and the amounts used for income tax purposes. Significant components of
the Company's deferred tax liabilities and assets include temporary differences
relating to depreciation, capitalized leases and certain revenues and expenses.

EARNINGS PER SHARE

Basic earnings per share is computed based on the weighted average number of
shares of common stock outstanding during the year. Diluted earnings per share
is computed by adjusting the weighted average shares outstanding by common stock
equivalents attributable to dilutive options.

COMPENSATION TO EMPLOYEES

Stock based compensation to employees is accounted for based on the intrinsic
value method under Accounting Principles Board Opinion No. 25, Accounting for
Stock Issued to Employees.

NEW ACCOUNTING PRONOUNCEMENTS

In 1997, the Financial Accounting Standards Board issued Statement No. 128,
Earnings per Share (SFAS 128). The standard replaced the calculation of primary
and fully diluted earnings per share with basic and diluted earnings per share.
Unlike primary earnings per share, basic earnings per share excludes any
dilutive effects of options, warrants and convertible securities. Diluted
earnings per share is very similar to the previously reported fully diluted
earnings per share. All earnings per share amounts for all periods have been
presented, and where appropriate, restated to conform to the SFAS 128
requirements.

                    NOTES TO FINANCIAL STATEMENTS (CONTINUED)

In 1997, the Financial Accounting Standards Board issued Statement of Financial
Accounting Standards No. 130, Reporting Comprehensive Income (SFAS No. 130). The
provisions of SFAS No. 130 require companies to classify items of comprehensive
income by their nature in a financial statement and display the accumulated
balance of other comprehensive income separately from retained earnings and
additional paid-in capital in the financial statements. The Company's
comprehensive income items are not material; accordingly, the effect of adopting
this statement will not be material when it becomes effective for fiscal 1998.

2.  PREPAID EXPENSES AND OTHER CURRENT ASSETS

                    NOTES TO FINANCIAL STATEMENTS (CONTINUED)

4.   LONG-TERM DEBT (CONTINUED)

(1)      The Company's revolving credit agreement (the "Line of Credit")
         provides for available borrowings of $28,500,000, including letters of
         credit not exceeding $5,000,000. The Line of Credit matures on April
         30, 2000, prior to which time, subject to certain conditions, the
         remaining balance may be converted at any time at the Company's option
         to a term loan requiring forty-eight equal monthly principal payments
         plus interest. The Company has outstanding letters of credit of
         approximately $1,110,000 at December 31, 1997. The credit facility
         bears variable interest (8.50% at December 31, 1997) based on the
         lenders prime rate, prime plus 1/2% or LIBOR. A quarterly commitment
         fee of 1/4% per annum is payable on the unused credit line. The Line of
         Credit is collateralized by accounts receivable and all otherwise
         unencumbered equipment.

              The Line of Credit requires the Company to meet certain financial
         covenants and to maintain a minimum tangible net worth of approximately
         $33,500,000 at December 31, 1997. The Company was in compliance with
         these covenants at December 31, 1997. The covenants would prohibit the
         payment of dividends by the Company if such payment would cause the
         Company to be in violation of any of the covenants. The carrying amount
         reported in the balance sheet for borrowings under the Line of Credit
         approximates its fair value since the interest rate is variable.

(2)      The leases extend through January, 2002 and contain renewal or fixed
         price purchase options. The effective interest rates on the leases
         range from 3.6% to 7.9% at December 31, 1997. The lease agreements
         require the Company to pay property taxes, maintenance and operating
         expenses. In 1995 the Company made security deposits of $1,745,478
         relating to certain of these leases.

The Company made interest payments of approximately $1,454,000, $793,000 and
$837,000 during 1997, 1996 and 1995, respectively. The Company capitalized
$86,600 and $85,800 in interest as a result of construction of its new corporate
office building during 1997 and 1996, respectively.

5.  LEASES AND COMMITMENTS

Capital lease obligations of $12,416,151, $6,141,601 and $4,107,008 were
incurred during the years ended December 31, 1997, 1996 and 1995, respectively.

At December 31, 1997 the future minimum payments under capitalized leases with
initial terms of one year or more were $7,207,075 for 1998, $5,829,344 for 1999,
$5,710,015 for 2000, $5,306,635 for 2001 and $13,280 in 2002. The present value
of net minimum lease payments was $21,967,940 which includes the current portion
of the capital leases of $6,285,986 and excludes amounts representing interest
of $2,085,129.

At December 31, 1997 property and equipment included capitalized leases which
had capitalized costs of $27,246,295, accumulated amortization of $6,075,925 and
a net book value of $21,170,370. At December 31, 1996 property and equipment
included capitalized leases which had capitalized costs of $22,278,560,
accumulated amortization of $6,856,908 and a net book value of $15,421,652.
Amortization of leased assets is included in depreciation and amortization
expense.

Commitments to purchase revenue equipment, which are cancelable by the Company
if certain conditions are met, aggregated approximately $36 million at December
31, 1997.

9.   COMMON STOCK TRANSACTIONS

The Company has a stock option plan which provides for the granting of incentive
or nonqualified options to purchase up to 800,000 shares of Common Stock to
officers and other key employees. No options may be granted under this plan for
less than the fair market value of the Common Stock at the date of the grant.
Although the exercise period is determined when options are actually granted, no
option will be exercised later than 10 years after it is granted.

The Company also has a nonqualified stock option plan for directors who are not
officers or employees of the Company, which provides for the granting of options
to purchase up to 50,000 shares of Common Stock. The exercise period for options
granted under the plan will begin three years after the date of grant and end
five years after such date, provided that an option will terminate upon the
termination of a holder's service as a director of the Company, subject to
certain grace periods if such termination of service occurs after the option has
vested.

A summary of the Company's stock option activity, and related information for
the years ended December 31, follows:

</TABLE>
                              
Exercise prices for options outstanding as of December 31, 1997 ranged from
$6.25 to $13.00 The weighted-average fair value of options granted during 1997
and 1996 were $4.46 and $3.86, respectively. The weighted-average remaining
contractual life of these options is 4.52 years.

In 1997, 1996 and 1995, 60,007, 38,210 and 24,280 options, respectively, were
exercised for cash. In 1997 and 1996 additional options of 3,313 and 3,190
respectively, were exercised by the exchange of 2,588 and 2,492 shares of stock
respectively, (with a market value equal to the exercise price of the options).
The exchanged shares were then canceled.

The Company has adopted the disclosure-only provisions of Statement of Financial
Accounting Standards No. 123, Accounting for Stock-Based Compensation (SFAS
123). Accordingly, no compensation cost has been recognized for the stock option
plans. Had compensation cost for the Company's two stock option plans been
determined based on the fair value at the grant date for awards in 1997 and 1996
consistent with the provisions of SFAS 123, the Company's pro forma net income
would have been $7,852,172 and $3,346,948 and pro forma earnings per share would
have been $.83 and $.35. There were no options granted in 1995.

The fair value of each option grant is estimated on the date of grant using the
Black-Scholes option-pricing model. The following weighted-average assumptions
were used for grants in 1997: dividend yield of 0%; expected volatility of
0.535%; risk-free interest rates range from 5.45% to 6.17% and expected lives
range from 3 to 5 years. The following weighted-average assumptions were used
for grants in 1996: dividend yield of 0%; expected volatility of 0.884%;
risk-free interest rates range from 5.24% to 6.65% and expected lives range from
3 to 6 years.

                           weekly yield per annum on United State Treasury
                           securities adjusted to having a constant maturity
                           equal to the applicable Interest Period (e.g., one
                           year or two years) for such Fixed Rate Loan reported
                           weekly and constructed by the United States Treasury
                           Department, based on actually traded marketable
                           United States Treasury securities, as published by
                           the Board of Governors of the Federal Reserve System

                           published Fixed Rate as of the date of each Fixed
                           Rate Loan shall be the applicable Fixed Rate under
                           the Revolving Note or the Term Note, as applicable,
                           for such Fixed Note Loan. If the foregoing technique
                           for determining the average weekly yield and the
                           resulting Fixed Rate is no longer available as of the
                           dated of a Fixed Rate Loan for computation thereof,
                           of the applicable Fixed Rate otherwise becomes
                           unascertainable, Lender in its sole discretion shall

                                            December 31, 1997.

                                            or decrease in this index prior to
                                            funding will result in an adjustment
                                            to the Lease Rate Factor(s).

EXPIRY                                      If the final Closing Date has not
                                            occurred by December 31, 1997, this
                                            Commitment will lapse.

INSURANCE                                   The Lessee shall procure insurance
                                            acceptable to Lessor and Lessee.
                                            Lessor recognizes and accepts that
                                            Lessee is self-insured for property
                                            damage.

END OF LEASE OPTIONS                        Lessee will have the following
                                            options:

                                            1)Purchase the Equipment for the
                                            TRAC amount which shall be equal to
                                            forty percent (40%) of the original
                                            Acquisition Cost for any TRAC Lease
                                            Schedule.

                                            2)Lessee, on behalf of Lessor, shall
                                            cause the Equipment to be sold to a
                                            third party. Lessor shall also have
                                            right, but not the obligation, to
                                            procure bids for the Equipment. If
                                            the net proceeds of the sale of the
                                            Equipment are less than the TRAC
                                            amount of 40% of the original
                                            Acquisition Cost, then Lessee will
                                            pay to Lessor the deficiency, as a

ADJUSTMENTS TO RENT:                        The current Rent Factor is based 
                                            upon the U.S. Treasury Note Index of
                                            5.69% (April, 2001 Treasury Note)
                                            per annum as of October 27, 1997. If
                                            the U.S. Treasury Note Index
                                            increased or decreases before the
                                            funding date of a Lease Schedule,
                                            then the applicable Rent Factor
                                            shall be adjusted to reflect the
                                            effect of the change in the U.S.
                                            Treasury Note Index on the original
                                            implicit rate associated with the
                                            original Rent Factor. However, once
                                            a Lease Schedule is funded, the Rent
                                            Factor for that Lease Schedule will
                                            remain fixed for the Lease Term.

                                            November 21, 1997.

PROPOSAL ONLY:                              This  letter  is  not  a   
                                            commitment to undertake this
                                            specific financing. A commitment can
                                            be issued only after full economic
                                            review and subsequent approval by
                                            the appropriate officers of Lessor.
                                            Lessor reserves the right to decline
                                            the issuance of a commitment for any
                                            reason whatsoever. If a commitment
                                            is issued by Lessor, it may modify
                                            the terms of this proposal and may
                                            add such additional requirements
                                            (including, but not limited to,
                                            requirements of guaranties or other
                                            credit support, and/or special

                                            conditions) as Lessor may deem
                                            advisable. A commitment shall not be
