<p style="margin:0pt 0pt 12.0pt 18.0pt;text-indent:-18.0pt;"><b><font size="2" face="Times New Roman" style="font-size:10.0pt;font-weight:bold;">Item 7.01&#160;&#160;&#160;&#160;&#160;&#160; Regulation FD Disclosure</font></b></p>

<p style="margin:0pt 0pt 12.0pt;"><font size="2" face="Times New Roman" style="font-size:10.0pt;">Marten Transport, Ltd.
(the &#147;Company&#148;) hereby furnishes the information contained in this Item 7.01 to
update investors on certain operating measures and correct certain information
that is in the market.</font></p>

<p style="margin:0pt 0pt 12.0pt;"><font size="2" face="Times New Roman" style="font-size:10.0pt;">Thus far in the third
quarter of 2007, the Company has experienced the same downturn in freight
demand that the industry as a whole has experienced.&#160; While freight demand did improve somewhat in
the second half of August and the first week of September, the Company does not
expect the increase to overcome overall demand declines.&#160; The Company expects rates in the third
quarter of 2007 to be generally flat, or slightly off, when compared to the
third quarter of 2006.</font></p>

<p style="margin:0pt 0pt 12.0pt;"><font size="2" face="Times New Roman" style="font-size:10.0pt;">To address soft demand,
the Company has identified improving its percentage of non-revenue miles as a
productive method of increasing margins without attempting to raise rates.&#160; The Company&#146;s non-revenue miles, which were
7.4% of total miles in the second quarter of 2006 and 7.8% of total miles in
the second quarter of 2007, have improved slightly thus far in the third
quarter of 2007 as compared to the second quarter of 2007.&#160; On a fleet-wide blended basis, the Company&#146;s
non-revenue miles for the months of July and August were 7.3% of total
miles.&#160; The Company&#146;s long-haul over the
road non-revenue miles are marginally better than the fleet-wide blended
average, but the Company does not provide a breakout of the difference between
the fleet-wide blended average of non-revenue miles and long-haul over the road
non-revenue miles.</font></p>

<p style="margin:0pt 0pt 12.0pt;"><font size="2" face="Times New Roman" style="font-size:10.0pt;">On the cost savings
front, the Company has recently begun the process of installing auxiliary power
units, which, based upon the Company&#146;s limited experience, can reduce fuel
consumption by up to 80% when compared with tractor-engine idling.&#160; At a cost of $2.80 per gallon, and assuming a
Company fleet of 2,184 tractors (the number of company-owned tractors as of
June 30, 2007), the Company estimates that approximately $400 per tractor per
month in fuel expense savings could be achieved through idle time
reductions.&#160; Any savings in fuel expense
would partially be offset by an estimated $100 per tractor per month increase
in depreciation expense and an estimated $45 per tractor per month increase in
interest expense initially, which would decline as related debt is
retired.&#160; The Company also hopes to
reduce wear and tear on tractor engines and to enhance driver satisfaction with
the auxiliary power units.</font></p>

<p style="margin:0pt 0pt 12.0pt;"><font size="2" face="Times New Roman" style="font-size:10.0pt;">The Company&#146;s internal
brokerage operations have substantially increased with revenue of approximately
$4.8 million in the first half of 2007 compared with approximately $5.0 million
in fiscal 2006.&#160; The operating ratio of
the Company&#146;s brokerage operations fluctuates around 95%.&#160; The Company&#146;s intermodal operations have also
grown substantially since their inception in the fourth quarter of 2005.&#160; Intermodal revenue was approximately $9.0
million in the first half of 2007 compared with approximately $12.6 million in
fiscal 2006.&#160; The operating ratio of the
Company&#146;s intermodal operations is approximately 85%.&#160; The results of the Company&#146;s brokerage and
intermodal operations are reported and included in the Company&#146;s Logistics
segment.</font></p>


 <p style="margin:24.0pt 0pt .0001pt;text-align:center;"><font size="2" face="Times New Roman" style="font-size:10.0pt;">2</font></p> <br><hr size="3" width="100%" noshade color="#010101" align="center">

<br clear="all" style="page-break-before:always;">


<p style="margin:0pt 0pt 12.0pt;"><font size="2" face="Times New Roman" style="font-size:10.0pt;">Driver turnover
year-to-date through August was approximately 83%.&#160; The Company notes that the driver market
continues to be challenging, but that the Company&#146;s average turnover compares
favorably with the industry as a whole.&#160;
Driver turnover in 2006 was approximately 73%.</font></p>

<p style="margin:0pt 0pt 12.0pt;"><font size="2" face="Times New Roman" style="font-size:10.0pt;">The Company previously
disclosed in its 2007 second quarter financial results that it expected a
decrease in the number of planned revenue equipment dispositions.&#160; The decrease in the number of planned revenue
equipment dispositions has continued into the third quarter of 2007.&#160; The Company has continued to restrict the number
of revenue equipment dispositions due to a relatively weak market for used
equipment and its ability to continue operating used equipment given the
quality of the equipment, which has resulted in a delay in placing
approximately 385 parked tractors in service.</font></p>

<p style="margin:0pt 0pt 12.0pt;"><font size="2" face="Times New Roman" style="font-size:10.0pt;">The 385 tractors that the
Company delayed placing in service are equipped with 2006 engines, which the
Company took delivery of in order to offset expected losses in productivity and
increased expenses associated with 2007 engines, which have more restrictive
emissions standards.</font></p>

<p style="margin:0pt 0pt 12.0pt;"><font size="2" face="Times New Roman" style="font-size:10.0pt;">Future revenue equipment
purchases will continue to be dependent upon a number of factors, including the
cost of capital, the market for used and new equipment, the freight market
generally, and the Company&#146;s results of operations.&#160; The Company does not expect to need to begin
purchasing new equipment until sometime during the second half of 2008, which
could result in capital expenditures of approximately $30-$35 million in 2008,
although the Company may adjust such expectations in light of market
conditions.</font></p>

<p style="margin:0pt 0pt 12.0pt;"><font size="2" face="Times New Roman" style="font-size:10.0pt;">Assuming capital
expenditures in line with the Company&#146;s current projections and no further
deteriorations in the freight market, the Company expects to generate cash flow
to retire a substantial amount of debt that would enable it to be net debt-free
sometime during the last half of 2008.&#160;
The Company&#146;s main priority for any excess cash flow would be to pay
down the Company&#146;s debt.&#160; After retiring
the Company&#146;s debt with any free cash flow, the Company expects its next
priority would be to build up a cash reserve on the balance sheet in order to
pre-fund the next major trade cycle of revenue equipment.</font></p>
