       SMITHWAY MOTOR XPRESS CORP. REPORTS IMPROVED SECOND QUARTER RESULTS

FORT DODGE,  IOWA (PR  Newswire)  August 1,  2003--Smithway  Motor  Xpress Corp.
(Nasdaq SmallCap Market:  SMXC) announced today financial and operating  results
for the second quarter and six months ended June 30, 2003.

For the quarter, operating revenue decreased approximately 6.6% to $42.2 million
from $45.2 million for the  corresponding  quarter in 2002.  Smithway's net loss
was $458,000,  or ($0.09) per basic and diluted share, compared with net loss of
$1.2 million,  or ($0.24) per basic and diluted  share,  for the same quarter in
2002.

For the first six months in 2003, operating revenue decreased approximately 5.0%
to $82.1 million from $86.5 million for the first six months in 2002. Smithway's
net loss was $2.0 million, or ($0.42) per basic and diluted share, compared with
net loss of $3.2 million,  or ($0.66) per basic and diluted share, for the first
six months in 2002.

The improvement in performance is primarily  attributable to decreased  expenses
resulting  from  ongoing  cost  containment  efforts.  On a cost per mile basis,
comparing  second quarter 2003 to second quarter 2002 non-driver wages decreased
20.6%,  fringe benefits  decreased  12.0%,  fuel expense,  net of fuel surcharge
revenue,  decreased 7.9% and general and  administrative  costs decreased 20.7%.
Following  the  end  of  the  quarter,   five  operating   terminals  have  been
consolidated  into existing  locations and two maintenance  facilities have been
closed.  These  measures are a part of the  Company's  initiatives  to return to
profitability.

Following the end of the quarter the Company  obtained waivers for loan covenant
violations at June 30, 2003.  Additionally,  the primary lender extended the due
date of the credit agreement to July 1, 2004.

In other matters,  the Company has scheduled its annual shareholders meeting for
Friday, October 24, 2003, at 10:00 a.m. in Fort Dodge, Iowa.

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
