               SMITHWAY MOTOR XPRESS CORP. REPORTS FOURTH QUARTER
             AND YEAR END RESULTS; FILES ANNUAL REPORT ON FORM 10-K;
               AND ANNOUNCES AMENDMENTS TO FINANCING ARRANGEMENTS
                         AND FIRST QUARTER EXPECTATIONS

FORT DODGE,  IOWA (PR  Newswire)  April 18,  2003--Smithway  Motor  Xpress Corp.
(Nasdaq SmallCap Market:  SMXC) announced today financial and operating  results
for the fourth  quarter and year ended  December  31,  2002.  The  Company  also
announced that it has negotiated amendments to its primary credit facilities and
has filed its  annual  report on Form 10-K with the SEC.  Finally,  the  Company
commented on its expectations concerning financial results for the first quarter
of 2003.

For the quarter, operating revenue decreased approximately 7.9% to $39.7 million
from $43.1 million for the  corresponding  quarter in 2001.  Smithway's net loss
was $4.7 million, or ($0.97) per basic and diluted share, compared with net loss
of $2.3 million, or ($0.48) per basic and diluted share, for the same quarter in
2001.

For the year, operating revenue decreased  approximately 11.2% to $169.5 million
from $190.8 million in 2001. The Company's net loss in 2002 was $8.7 million, or
($1.79) per basic and diluted share,  compared with net loss of $5.2 million, or
($1.07) per basic and diluted share, for 2001.

The  fourth  quarter  results  included  pre-tax  adjustments  of $5.1  million,
comprised  of a  $3.3  million  write-off  of  goodwill  associated  with  prior
acquisitions  and a  $1.8  million  increase  in  auto  liability  and  workers'
compensation loss reserves.  The fourth quarter of 2001 included $1.1 million in
pre-tax adjustments, including a $707,000 write-off of the carrying value of its
proprietary computer operating system and a $332,000 increase in its reserve for
bad debts.  The  Company's net loss prior to these  adjustments  would have been
$1.6  million or ($0.33) per share for the fourth  quarter  and $5.6  million or
($1.15) per share for the year ended  December 31, 2002.  This compares to a net
loss  before  adjustments  of $1.7  million or ($0.35)  per share for the fourth
quarter of 2001 and $4.6  million or  ($0.95)  per share for the year 2001.  The
main contributors to the loss before  adjustments in 2002 were decreased revenue
production of the tractor  fleet,  decreased  brokerage  revenue,  and increased
parts and maintenance expense. Management believes that presentation of earnings
calculated  to exclude the impact of the  adjustments  is useful to investors in
comparing of the Company's results of operations from period to period.



Chairman,  President,  and Chief  Executive  Officer  William G.  Smith  stated,
"During the fourth quarter we continued to pursue our previously  announced core
goals of improving  revenue per seated  tractor,  improving our van  operation's
performance,  decreasing our number of tractors without drivers,  and continuing
our commitment to safe operations.  For the quarter,  average revenue per seated
tractor per week  decreased by  approximately  1.0% versus the fourth quarter of
2001 as a one cent  increase  in revenue per loaded mile was more than offset by
fewer  revenue  miles per  tractor.  During  the  quarter,  our number of seated
tractors remained essentially constant.

Finally,  we continue to be very  pleased  with our safety  record.  In 2002 the
Company had its best safety year, in terms of accidents per million miles, since
going public in 1996. The increase in auto liability  reserves during the fourth
quarter  related to a change in  estimating  the  ultimate  cost of claims  that
occurred in prior years."

The Company also  announced that it filed its annual report on Form 10-K for the
year ended December 31, 2002,  with the  Securities  and Exchange  Commission on
April 15, 2003. The Company  previously had filed for an extension of the filing
date from March 31 to April 15. The Company filed for the extension because,  in
connection with the amendments to the Company's financing arrangements discussed
below, the Company and its outside auditors  required  additional time to review
the  impact of the  amendments  on the  Company's  financial  statements  and to
finalize the audit report.

Between  late March and mid April,  the  Company  negotiated  amendments  to its
financing  arrangement  with  LaSalle  Bank as well as its  equipment  financing
arrangement  with a  manufacturer.  The Company had been in violation of certain
financial covenants under the LaSalle facility at December 31 and expected to be
in violation under both the LaSalle  Agreement and the equipment  financing with
the manufacturer at March 31. The Company obtained waivers of all violations and
negotiated  amendments to the financial  covenants under both arrangements going
forward.  Under the LaSalle amendments the interest rate was raised by 200 basis
points and the facility's maturity is now April 1, 2004.

Commenting on the amendments to the Company's financing arrangements,  Mr. Smith
stated:  "We are pleased  that our lenders  have agreed to modify our  financial
covenants  to better align them with  management's  expectations  regarding  the
Company's  near term financial  performance.  For the first quarter of 2003, the
Company expects to report operating revenue of approximately $40 million,  and a
net loss of approximately  $1.6 to $1.7 million.  The net loss is expected to be
less  than the net loss in the  first  quarter  of 2002,  on a  revenue  base of
approximately $1.3 million less. Based upon anticipated results, we believe that
continued compliance with the revised covenants is reasonably achievable."

This press release and statements made by the Company in its stockholder reports
and   public   filings,   as  well  as  oral   public   statements   by  Company

identified by words such as "anticipates,"  "believes,"


"estimates," "projects," "expects," or similar expressions. These statements are
made pursuant to the safe harbor provisions of the Private Securities Litigation
Reform Act of 1995.  Such  statements  are based upon the  current  beliefs  and
expectations  of the Company's  management and are subject to significant  risks
and   uncertainties.   Actual  results  may  differ  from  those  set  forth  in
forward-looking  statements.  The following factors,  among others,  could cause
actual results to differ  materially from those in  forward-looking  statements:
failure to turn around continued operating losses, which could result in further
violation  of  bank  covenants  and  acceleration  of  indebtedness  at  several
financial institutions; the ability to obtain financing on acceptable terms, and
obtain  waivers and  amendments  to current  financing  in the event of default;
economic  recessions  or  downturns in  customers'  business  cycles;  excessive
increases in capacity within truckload markets;  surplus inventories;  decreased
demand for  transportation  services offered by the Company;  increases or rapid
fluctuations in inflation,  interest rates, fuel prices,  and fuel hedging;  the
availability  and  costs of  attracting  and  retaining  qualified  drivers  and
owner-operators;  increases in insurance  premiums and  deductible  amounts,  or
changes in excess coverage,  relating to accident, cargo, workers' compensation,
health,  and other claims;  the resale value of used equipment and prices of new
equipment;  seasonal  factors such as harsh  weather  conditions  that  increase
operating  costs;  regulatory  requirements  that  increase  costs and  decrease
efficiency,  including new emissions standards and hours-of-service regulations;
changes in management;  and the ability to negotiate,  consummate, and integrate
acquisitions. Readers should review and consider the various disclosures made by
the Company in this press release,  stockholder  reports, and in its Forms 10-K,
10-Q, and other public  filings.  The Company  disclaims any such  obligation to
