                          Independent Auditors' Report



The Plan Trustees
Smithway Motor Xpress, Inc. 401(k) Retirement Savings and Investment Plan:


We have audited the  statements  of net assets  available  for plan  benefits of
Smithway Motor Xpress,  Inc. 401(k) Retirement Savings and Investment Plan as of
December 31, 2001 and 2000, and the related  statements of changes in net assets
available for plan benefits for the years then ended. These financial statements
are the  responsibility  of the  Plan's  management.  Our  responsibility  is to
express an opinion on these financial statements based on our audits.

We conducted our audits in accordance with auditing standards generally accepted
in the  United  States of  America.  Those  standards  require  that we plan and
perform the audit to obtain  reasonable  assurance  about  whether the financial
statements are free of material misstatement.  An audit includes examining, on a
test basis,  evidence  supporting  the amounts and  disclosures in the financial
statements.  An audit also includes assessing the accounting principles used and
significant  estimates  made by  management,  as well as evaluating  the overall
financial  statement  presentation.   We  believe  that  our  audits  provide  a
reasonable basis for our opinion.

In our opinion,  the financial  statements  referred to above present fairly, in
all material  respects,  the net assets  available for plan benefits of Smithway
Motor Xpress,  Inc. 401(k) Retirement Savings and Investment Plan as of December
31, 2001 and 2000, and the changes in its net assets available for plan benefits
for the years then ended in  conformity  with  accounting  principles  generally
accepted in the United States of America.

Our audit of the  Plan's  financial  statements  as of and for the  years  ended
December  31,  2001 and 2000,  was made for the purpose of forming an opinion on
the  financial  statements  taken as a whole.  The  supplemental  schedule  1 is
presented for the purpose of  additional  analysis and is not a required part of
the basic financial statements, but is supplementary information required by the
Department of Labor's Rules and Regulations  for Reporting and Disclosure  under
the Employee  Retirement Income Security Act of 1974. The supplemental  schedule
has been subjected to the auditing procedures applied in the audits of the basic
financial  statements  and, in our opinion,  is fairly  stated,  in all material
respects, in relation to the basic financial statements taken as a whole.

                     RETIREMENT SAVINGS AND INVESTMENT PLAN

                          Notes to Financial Statements

                           December 31, 2001 and 2000


(1)  Summary of Significant Accounting Policies

     (a)  Plan Information and Basis of Presentation

          The accompanying  financial  statements of Smithway Motor Xpress, Inc.
          401(k)  Retirement  Savings and  Investment  Plan (the Plan) have been
          prepared on the  accrual  basis of  accounting  and are subject to the
          provisions  of the  Employee  Retirement  Income  Security Act of 1974
          (ERISA).  The Plan is  sponsored by Smithway  Motor Xpress Corp.  (the
          Company)  and has two entry dates per year.  Full-time  employees  are
          eligible  for  participation  in the Plan on the next entry date after
          completing one year of service.  Participants should refer to the Plan
          agreement for more complete information.

     (b)  Investments

          Investments,  other  than  loans,  are  reported  at  fair  value,  as
          determined by using available market information.  Purchases and sales
          of  securities   are  recorded  on  a  trade-date   basis.   Loans  to
          participants   are   valued  at  their   unpaid   principal   balance,
          representing estimated fair value.

          Net  investment  income  includes  investment  income,  realized gains
          (losses),  and unrealized  appreciation  (depreciation) on investments
          held.

     (c)  Administrative Fees

          Certain administrative fees are paid by the Company.

     (d)  Income Taxes

          The Internal  Revenue Service has issued a  determination  letter that
          the Plan is  qualified,  and the trust  established  under the Plan is
          tax-exempt,  under Sections 401(a) and 501(a) of the Internal  Revenue
          Code.  The Plan has been amended  since  receiving  the  determination
          letter.  An  updated  determination  letter  has not  been  requested;
          however,  UMB Bank (the Plan Administrator) and the Plan's tax counsel
          believe  the  Plan  is  currently   designed  and  being  operated  in
          compliance with the applicable  requirements  of the Internal  Revenue
          Code.  Therefore,  they believe the Plan was qualified and the related
          trust  was  tax-exempt  as of  December  31,  2001  and  2000.  Future
          qualification  of the Plan will  depend  on  continuing  operation  in
          compliance with the Internal Revenue Code.

     (e)  Use of Estimates

          The Plan  Administrator has made a number of estimates and assumptions
          relating to the reporting of assets, liabilities,  and changes therein
          to prepare these  financial  statements in conformity  with accounting
          principles generally accepted in the United States of America.  Actual
          results could differ from those estimates.

(2)  Net Assets Available for Benefits

     The Plan Administrator  maintains funds received from the Plan primarily in
     registered investment companies or in the Company's common stock.


                                       3                           (Continued)

                          Notes to Financial Statements

                           December 31, 2001 and 2000

(3)  Contributions

     Under the terms of the Plan agreement,  the Company may, at its discretion,
     make annual contributions to the Plan, which shall be allocated to eligible
     participants  based on a  percentage  of the  total  deferred  compensation
     contributed during the Plan year.  Forfeitures,  if any, are used to reduce
     future employer contributions.

     Employees may make voluntary  contributions  to the Plan up to 15% of their
     compensation,  subject  to certain  limitations  as  specified  in the Plan
     agreement.

(4)  Participant Accounts

     Each participant's account is credited with the participant's contribution,
     the  employer's  contribution,  and an  allocation of Plan  earnings.  Each
     participant  will be permitted to direct the Plan  Administrator  to invest
     their individual accounts into various approved investments permitted under
     the Plan.

     Participants are immediately  vested in their voluntary  contributions  and
     the earnings  thereon.  Vesting in the remainder of their accounts is based
     on years of service in which the  participant  has completed at least 1,000
     hours of service. A participant is 100% vested after six years of service.

(5)  Benefits

     Under the terms of the Plan agreement,  participants or their beneficiaries
     are eligible for benefits upon retirement,  death, or disability.  Benefits
     shall  be  distributed  through  one of  several  options  selected  by the
     participants, as defined in the Plan agreement.

(6)  Liabilities

     Liabilities  include refunds payable for excess  contributions  received by
