ITEM 9. REGULATION FD DISCLOSURE.

     On July 31,  2002,  Knight  Transportation,  Inc.,  an Arizona  corporation
("we," "our," "us," or the  "Company"),  reached a resolution of our  litigation
with Freightliner L.L.C.  ("Freightliner")  through successful mediation. We are
pleased to put this conflict behind us and we hope to develop a positive working
relationship with Freightliner in the near future.

     We  anticipate  that our  tractor  fleet will  increase  by 14% by year end
compared to our earlier  estimate of 12%. We expect to meet our targeted  growth
goals for 2002, and to continue to take advantage of increased  customer  demand
and meet our  customers'  needs.  We hope to  achieve a net  growth  of  revenue
equipment by year end of approximately 265 new tractors, net of trade-ins, which
is commensurate  with our original target. We will also continue to aggressively
pursue ways to meet the 2002 emissions standards  profitably.  We also intend to
continue  to  pursue  our  goal of  maintaining  dual  sources  for our  revenue
equipment.

     Our revenue, before fuel surcharge, for the six month period ended June 30,
2002,  increased 15.5% to $130,197,000  from $112,745,000 for the same period in
2001. We expect our revenue  before fuel  surcharge to continue to grow compared
to last year, assuming that business conditions continue to be favorable.
