                  Thursday, November 8, 2007,
                  Knight Transportation, Inc., an Arizona corporation (the "Company"),
                  announced that Mark Scudder will step down as a member of the Board
                  of
                  Directors effective November 9, 2007.&#160;&#160;&#160;Mr. Scudder will
                  remain securities and merger and acquisition counsel to the Company
                  and
                  will serve as a strategic legal advisor to the Board.&#160; In announcing
                  the move, Chairman and CEO Kevin Knight stated:&#160;"Mark has been a
                  close and important advisor to Knight Transportation for nearly
                  a decade,
                  during which our annual revenue base grew from approximately $150
                  million
                  in 1999 to approximately $700 million while expanding our geographic
                  footprint and portfolio of service offerings. As our activities
                  and Mark's
                  role have expanded and evolved, we jointly decided that his stepping
                  down
                  from his director role would be appropriate and would increase

                  the repurchase of up to 3.0 million shares of the Company's Common

On
                  Thursday, November 8, 2007,
                  Knight Transportation, Inc., an Arizona corporation (the "Company"),
                  announced that Mark Scudder will step down as a member of the Board
                  of
                  Directors effective November 9, 2007.   Mr. Scudder will
                  remain securities and merger and acquisition counsel to the Company
                  and
                  will serve as a strategic legal advisor to the Board.  In announcing
                  the move, Chairman and CEO Kevin Knight stated: "Mark has been a
                  close and important advisor to Knight Transportation for nearly
                  a decade,
                  during which our annual revenue base grew from approximately $150
                  million
                  in 1999 to approximately $700 million while expanding our geographic
                  footprint and portfolio of service offerings. As our activities
                  and Mark's
                  role have expanded and evolved, we jointly decided that his stepping
                  down
                  from his director role would be appropriate and would increase
                  flexibility
                  in the future.  The Board appreciates Mark's service and looks
                  forward to the continuing relationship."
Mr.
                  Scudder added: "Knight
                  has an outstanding Board of Directors and management team that
                  have
                  delivered industry-leading performance and shareholder returns
                  with great
                  integrity.  It has been an honor to serve on the Board, and I look
                  forward to continuing to serve the Company for many years to
                  come."
After
                  giving effect to Mr.
                  Scudder's resignation, the majority of the members of the Company's
                  Board
                  of Directors will continue to be independent.
Item
                  7.01
Regulation
                  FD Disclosure.
The
                  Company also announced today
                  that the Board of Directors of the Company voted unanimously to
                  authorize
                  the repurchase of up to 3.0 million shares of the Company's Common
                  Stock.  The repurchase authorization will continue in effect until
                  the share limit is reached or the program is terminated by the
                  Company.  The repurchase authorization is intended to afford the
                  Company the flexibility to acquire shares opportunistically in
                  future
                  periods and does not indicate an intention to repurchase any particular
                  number of shares within a definite timeframe.  Any repurchases would
                  be effected based upon share price and market conditions. The
                  authorization extends to purchases of shares to prevent dilution
                  from
                  equity compensation awards as well as open market and negotiated
                  transactions.
