Exhibit 99.1

                PRIVATE SECURITIES LITIGATION REFORM ACT OF 1995
         SAFE HARBOR COMPLIANCE STATEMENT FOR FORWARD-LOOKING STATEMENTS

     In  passing  the  Private  Securities  Litigation  Reform  Act of 1995 (the
"PSLRA"),   Congress  encouraged  public  companies  to  make   "forward-looking
statements"1 by creating a safe-harbor to protect  companies from securities law
liability in connection with  forward-looking  statements.  Swift Transportation
Co., Inc. ("Swift") intends to qualify both its written and oral forward-looking
statements for protection under the PSLRA.

     To qualify oral forward-looking  statements for protection under the PSLRA,
a readily available written document must identify  important factors that could
cause  actual  results to differ  materially  from those in the  forward-looking
statements.  Swift  provides the following  information  in connection  with its
continuing  effort to qualify  forward-looking  statements  for the safe  harbor
protection of the PSLRA.

     As to Swift's  business  and  financial  performance  generally,  important
factors  currently known to management that could cause actual results to differ
materially from those in forward-looking statements include, but are not limited
to,  the  following:   (i)  excess  capacity  in  the  trucking  industry;  (ii)
significant increases or rapid fluctuations in fuel prices, interest rates, fuel
taxes,  tolls,  license and  registration  fees and insurance  premiums,  to the
extent  not  offset by  increases  in freight  rates or fuel  surcharges;  (iii)
difficulty in attracting and retaining  qualified  drivers and owner  operators,
especially  in light of the  current  shortage  of  qualified  drivers and owner
operators;  (iv)  recessionary  economic  cycles  and  downturns  in  customers'
business cycles,  particularly in market segments and industries (such as retail
and  manufacturing)  in which the Company  has a  significant  concentration  of
customers;  (v) seasonal factors such as harsh weather  conditions that increase
operating costs; (vi) increases in driver  compensation to the extent not offset
by increases in freight rates; (vii) the inability of the Company to continue to
secure acceptable financing  arrangements;  (viii) the ability of the Company to
continue  to identify  acquisition  candidates  that will  result in  successful
combinations;  (ix) an unanticipated  increase in the number of claims for which
the Company is self insured;  (x) a significant  reduction in or  termination of
the  Company's  trucking  services  by a key  customer;  (xi)  the  loss  of key
executives;  (xii) new or more  comprehensive  regulations  with respect to fuel
emissions,  hours in service,  or  ergonomics;  (xiii) a spill or other accident
involving hazardous  substances;  (xiv) the depressed market for used equipment,
particularly tractors; and (xv) the possibility that the Company may not realize
the expected benefits of its litigation settlement with an insurance carrier.

     With respect to Swift's merger with M.S.  Carriers in the second quarter of
2001, these factors include, but are not limited to, the following: (i) the risk
that the revenue and other synergies and cost savings anticipated to result from
the  merger  may not be  fully  realized  or may take  longer  to  realize  than
expected;  (ii) the difficulty the stock market may have in valuing the business
model of the combined  company;  and (iii)  disruption from the merger making it
more  difficult  to  maintain  relationships  with  customers,   employees,   or
suppliers.

     Forward-looking  statements  express  expectations  of future  events.  All
forward-looking statements are inherently uncertain as they are based on various
expectations  and assumptions  concerning  future events and they are subject to
numerous  known and unknown  risks and  uncertainties  which could cause  actual
events or  results  to differ  materially  from  those  projected.  Due to these
inherent  uncertainties,  the  investment  community is urged not to place undue
reliance  on  forward-looking  statements.  In  addition,  Swift  undertakes  no
obligation to update or revise  forward-looking  statements  to reflect  changed
assumptions,  the occurrence of  unanticipated  events or changes to projections
over time.
