                  Transportation, Inc., an Arizona corporation (the "Company"), declared
                  a
                  3-for-2 stock split on all shares of the Company&#8217;s outstanding common
                  stock that will be effected in the form of a stock dividend. The
                  stock
                  split will entitle all shareholders of record as of the close of
                  business
                  on November&#160;30, 2005, to receive one additional share of common stock
                  for every two shares of common stock held on that date. The additional
                  shares will be distributed to shareholders on or about December&#160;23,
                  2005. Cash will be paid in lieu of issuing fractional shares. The
                  Company
                  currently has approximately 56.9&#160;million shares of common stock
                  outstanding, and after giving effect to the stock split, will have
                  approximately 85.4&#160;million shares outstanding.</font></div>

Stock
                  Split
On
                  Wednesday, November 9, 2005, the Board of Directors of Knight
                  Transportation, Inc., an Arizona corporation (the "Company"), declared
                  a
                  3-for-2 stock split on all shares of the Company's outstanding common
                  stock that will be effected in the form of a stock dividend. The
                  stock
                  split will entitle all shareholders of record as of the close of
                  business
                  on November 30, 2005, to receive one additional share of common stock
                  for every two shares of common stock held on that date. The additional
                  shares will be distributed to shareholders on or about December 23,
                  2005. Cash will be paid in lieu of issuing fractional shares. The
                  Company
                  currently has approximately 56.9 million shares of common stock
                  outstanding, and after giving effect to the stock split, will have
                  approximately 85.4 million shares outstanding.
Cash
                  Dividend
On
                  Wednesday, November 9, 2005, the Company's Board of Directors also
                  declared a cash dividend of $0.02 per share on its common stock.
The
                  dividend is payable to shareholders of record on January 31, 2006,
                  and is expected to be paid on February 14, 2006. The cash dividend
                  per
                  share expected to be paid on February 14, 2006, is the same amount
                  per share as paid for the past four quarters. However, with the
                  expected
                  increase in outstanding shares in relation to the stock split,
                  the
                  aggregate amount of the cash dividend is expected to increase by
                  approximately 50%. The Company currently expects to continue to
                  pay
                  quarterly cash dividends in the future.
The
                  actual declaration of future cash dividends, and the establishment
                  of
                  record and payment dates, is subject to final determination by
                  the Board
                  of Directors each quarter after its review of the company's financial
                  performance.
Future
                  payment of cash dividends, and the amount of any such dividends,
                  will
                  depend upon financial condition, results of operations, cash requirements,
                  tax treatment, and certain corporate law requirements, as well
                  as other
                  factors deemed relevant by the Company's Board of Directors.
A
                  copy of the press release issued by the Company on November 14,
                  2005, is
                  attached to this report as Exhibit 99.1.

On
                  Wednesday, November 9, 2005, the Board of Directors of the Company
                  also
                  named Kathryn L. Munro to succeed Mark A. Scudder as Chairperson
                  of the
                  Compensation Committee. Ms. Munro was appointed to the Company's Board of

                  Securities
                  Exchange Act of 1934, as amended. Such statements are made based
                  on the

                  are
                  subject to significant risks and uncertainties. Actual results

                  may differ from those anticipated by forward-looking statements.
In
                  particular, our declaration of future dividends is subject to various
                  risks and uncertainties, including: our inability to declare a

                  compliance with applicable laws; restrictions on the payment of
                  dividends

                  arrangements; changes in tax laws relating to corporate dividends;
                  a
                  determination by the Board of Directors that the declaration of
                  a dividend
                  is not in the best interests of the company and its shareholders;
                  an
                  increase in our cash needs or a decrease in available cash; or
                  a
                  deterioration in our financial condition or results, including
                  as a result
                  of those risks, uncertainties, and other factors identified from
