Operating Income               $   6.7      $   9.9      -31.8%

                         (In millions except per share data)
Operating revenues for the first quarter of 2001 increased nine percent to
$182.2 million from $167.1 million in the same period 2000.   Operating income
for the first quarter of 2001 was $6.7 million, a 31.8 percent decrease from
$9.9 million in the same period 2000.  Net income for the quarter ending March
31, 2001 was $1.1 million, a 77.0 percent decrease from $4.6 million in the
first quarter of 2000.  Diluted earnings per share for the first quarter of 2001
were nine cents, a decrease of 76.3 percent from 38 cents for the same quarter
last year.
Mike Starnes, chairman and chief executive officer said:  "Softness in the
truckload freight markets during the first quarter of 2001 lowered our operating
margins primarily through a greater percentage of non-revenue miles.  The months
of January and February 2001 were particularly affected by this factor.  Market
conditions improved in March but were still down compared to last year.
"We are progressing with the merger with Swift Transportation that was announced
December 11, 2000.  During this quarter, M.S. Carriers accrued $0.02 per share
for merger related expenses.  We expect to close the merger in the second
quarter of 2001."
M.S. Carriers will hold a conference call on April 18, 2001 at 9:00a.m. CDT
regarding the first quarter earnings.  The call may be accessed at (888) 423-
3275 in the United States or (612) 332-0418 Internationally.  The conference
call will be available for replay from 12:30 p.m. CDT, April 18, 2001 until

This press release contains certain forward-looking statements within the
meaning of the Private Securities Litigation Reform Act of 1995.  This
information is in accordance with the company's current expectations and is
subject to certain risks and uncertainties that could cause actual results to
differ materially from those set forth in the forward-looking statements. With
respect to M.S. Carriers' financial results these uncertainties include, without
limitation, the following: M.S. Carriers will have reasonable success recruiting
and retaining experienced drivers and owner operators at the company's current
compensation level; demand and pricing for the markets served by M.S. Carriers
will remain at current levels; fuel will remain available and without rapid
price fluctuations; and the company's accident experience will remain at
historical levels. With respect to
                                    1


the proposed merger transaction with Swift these uncertainties include, without
limitation, the following: the inability to obtain governmental approvals of the
merger on the proposed terms and schedule; the failure of M.S. Carriers and
Swift stockholders to approve the merger; the risk that the businesses will not
be integrated successfully; the risk that the revenue synergies and costs
savings anticipated from the merger may not be fully realized or may take longer
to realize than expected; the risk that additional insurance and claims reserves
and expenses may be incurred; disruptions from the merger making it more
difficult to maintain relationships with customers, employees or suppliers; and
increased competition and its effects on pricing, spending, third-party
relationships and revenues.  Additional factors that could cause results to
differ materially from those described in the forward-looking statements can be
found in the 2000 Annual Report on Form 10-K of M.S. Carriers with the
Securities Exchange Commission.

This press release is being filed with the SEC pursuant to Rule 425 under the
Securities Act of 1933.
