ITEM 7. EXHIBITS.

     (c) Exhibits

          (99) Slide Presentation of Swift Transportation Co., Inc.

ITEM 9. REGULATION FD DISCLOSURE.

     Swift has prepared a slide presentation that it intends to utilize in
future meetings with investors, stockholders, and analysts. A copy of the slide
presentation is filed herewith as Exhibit 99.

     While Swift does not believe that the slide presentation includes any
previously non-public material information, it has elected to furnish this
information in this Report.

     Certain information in this filing consists of forward-looking statements
within the meaning of the Private Securities Litigation Reform Act of 1995. Such
statements include, but are not limited to, statements concerning Swift's future
growth, Swift's projected revenues in 2003, Swift's ability to recruit and train
qualified drivers, Swift's low operational costs, the benefits of Swift's
terminal network, including fuel cost savings, Swift's use of guaranteed return
agreements to lessen the impact of the declining used truck market, Swift's use
of surcharges to lessen the impact of fuel price increases, the anticipated
closing of the acquisition of M.S. Carriers in the second quarter of 2001, the
integration of Swift and M.S. Carriers by January 2002, revenue synergies from
cross-selling and growth in international business expected to result from the
acquisition of M.S. Carriers, Swift's ability to address low freight demand by
increasing business volume with existing customers and cross-selling to
customers of M.S. Carriers, the acceleration of cost synergies associated with
the acquisition of M.S. Carriers to 2002, savings in health and liability
insurance expenses expected to result from the acquisition of M.S. Carriers, and
future opportunities for well-capitalized trucking companies, including the
elimination of competitors, the elimination of excess capacity, and increased
driver availability.

     Such forward-looking statements are based upon the current beliefs and
expectations of Swift's management and are subject to significant risks and
uncertainties. Actual results may differ from those set forth in the
forward-looking statements. As to Swift's business and financial performance
generally, the following factors, among others, could cause actual results to
differ materially from those in forward-looking statements: excess capacity in
the trucking industry; significant increases or rapid fluctuations in fuel
prices, interest rates, fuel taxes, tolls, license and registration fees,
insurance premiums, and driver compensation, to the extent not offset by
increases in freight rates or fuel surcharges; an unanticipated number of claims
for which Swift is self-insured; difficulty in attracting and retaining
qualified drivers and owner operators, especially in light of the current
shortage of qualified drivers and owner operators; recessionary economic cycles
and downturns in customers' business cycles, particularly in market segments and
industries (such as retail and manufacturing) in which Swift has a significant
concentration of customers; a significant reduction in or termination of the
Company's trucking services by a key customer; seasonal factors such as harsh
weather conditions that increase operating costs; the inability of Swift to
continue to secure acceptable financing arrangements; and the ability of Swift
to continue to identify and combine acquisition candidates that will result in
successful combinations. With respect to the proposed acquisition of M.S.
Carriers, these risks and uncertainties include, but are not limited to, the
following: the ability to obtain governmental approvals of the merger on the
proposed terms and schedule; the failure of Swift's and M.S. Carriers'
stockholders to approve the merger; the risk that the businesses will not be
integrated successfully; the risk that the revenue and other synergies and cost
savings from the merger may not be fully realized or may take longer to realize
than expected; fluctuating stock market levels that could cause Swift's stock
value to be less than the current Swift or M.S. Carriers stock value; the
difficulty the stock market may have in valuing the business model of the
combined company; and disruption from the merger making it more difficult to
maintain relationships with customers, employees, or suppliers.

                                        2

     A discussion of these and other factors that could cause Swift's results to
differ materially from those described in the forward-looking statements can be
found in the most recent Annual Reports on Forms 10-K of Swift, filed with the
Securities and Exchange Commission and available at the Securities and Exchange
Commission's internet site (http://www.sec.gov).
