     SMITHWAY MOTOR XPRESS CORP. ANNOUNCES CONTINUED IMPROVED PROFITABILITY

FORT DODGE, IOWA (PR NEWSWIRE) OCTOBER 29, 2004--Smithway Motor Xpress Corp.
(Nasdaq SmallCap Market: SMXC) announced today financial and operating results
for the third quarter and nine months ended September 30, 2004.


For the third quarter of 2004, operating revenue increased approximately 14.6%
to $48.7 million from $42.5 million for the corresponding quarter in 2003. Net
earnings were $854,000, or $0.18 per basic and $0.17 per diluted share, compared
with net loss of ($305,000), or ($0.06) per basic and diluted share, for the
same quarter in 2003.



For the first nine months of 2004, operating revenue increased approximately
11.5% to $138.9 million from $124.6 million for the first nine months in 2003.
Net earnings were $1.9 million, or $0.38 per basic share and diluted share,
compared with net loss of ($2.3 million), or ($0.48) per basic and diluted
share, for the first nine months of 2003.



Net earnings for the first nine months of 2004 include $727,000, or $0.15 per
basic and diluted share, of tax-free life insurance proceeds received during the
first quarter. Without the life insurance proceeds, net earnings for the first
nine months would have been $1.1 million, or $0.23 per basic and diluted share,
compared with net loss of ($2.3 million), or ($0.48) per basic and diluted
share, for the first nine months of 2003.



G. Larry Owens, President and Chief Executive Officer, commented, "Smithway's
results for the third quarter 2004 mark our highest quarterly earnings since the
second quarter of 1999. For the quarter, average revenue per seated tractor per
week increased by $290, or 11.0%, compared to the third quarter of 2003 as we
continued our focus on asset productivity and lane flow and as freight demand
increased, allowing for a nine cent increase in revenue per loaded mile,
increased revenue miles per tractor, and decreased deadhead.



Higher truck production and freight rates have allowed us to absorb a two cent
per mile driver pay increase and unusually high fuel prices. Almost all of our
trucks, which we are replacing at




the rate of 20 units per month, are seated with a driver. We are pleased with
our continued profitability and look forward to further improvement."

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

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 sustain the
recent return to quarterly operating profitability, which could result in
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 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,
