ITEM 1. CHANGES IN CONTROL OF REGISTRANT.

     Not applicable.

ITEM 2. ACQUISITION OR DISPOSITION OF ASSETS.

     On March 19, 2000, Knight Transportation,  Inc. ("Knight" or the "Company")
purchased  all of the  outstanding  capital stock of John Fayard  Freight,  Inc.
d/b/a/  Fastway  Systems  ("Fastway").   Fastway  is  a  privately-held  company
headquartered  in  Gulfport,   Mississippi,   which  operates   primarily  as  a
short-to-medium  haul truckload  carrier in the Southeast and Gulf Coast regions
of the United States.  Prior to the  acquisition,  Fastway also operated a local
warehousing,  moving and storage  business in the Gulfport  and Mobile,  Alabama
areas. Contemporaneously with the transaction, Fastway redeemed a portion of its
capital stock and distributed all of its real estate and  improvements,  as well
as the assets and certain  liabilities  associated with its warehousing,  moving
and  storage  business,  to its former sole  stockholder,  John R.  Fayard,  Jr.
("Fayard").

     Fastway's assets consisted of approximately  222 tractors and 588 trailers,
as well as  cash,  accounts  receivable,  and  other  miscellaneous  assets.  In
addition,  Fastway retained certain short and long term debt relating to revenue
equipment.  Knight  intends to  continue  operating  the  Fastway  assets in its
truckload business.

     As consideration for the acquisition, Knight paid Fayard $4,000,000 in cash
and issued 228,788 shares of Knight's  unregistered and restricted common stock.
Knight has agreed to  register  the common  stock  issued to Fayard in the event
Knight files a  registration  statement for its common  stock,  other than stock
issued through employee  benefit plans or dividend  reinvestment  programs.  The
common  stock issued by Knight were  treasury  shares  which  resulted  from the
Company's  repurchase  of its  common  stock  during  1999.  Subject  to a floor
limitation  of $10.00 per share on the value of such shares when issued,  Knight
may issue up to  105,000  additional  shares  of stock to  Fayard  and pay up to
$1,155,000 in cash bonuses to certain  current full time  employees of Fayard if
the operations of Fastway reach certain  performance  targets over the two years
following  closing.  Knight  also  agreed to employ Mr.  Fayard for three  years
following  the closing as President  of Fastway,  and Mr.  Fayard  agreed not to
compete for five years following his last day of employment.

     Knight used funds available under its line of credit with Wells Fargo Bank,
N.A. to fund the cash portion of the purchase price. The purchase  consideration
was  determined  through arm's length  negotiation  between  representatives  of
Knight  and Mr.  Fayard  and his  representatives.  Prior  to the  close  of the
transaction, there was no material relationship between Mr. Fayard and Knight or
any of its  affiliates,  any director or officer of Knight,  or any associate of
any such director of officer.

     The terms of Knight's  acquisition  of Fastway are more fully  described in
the Stock Purchase Agreement and related acquisition documents,  copies of which
are attached hereto as Exhibit 2.1 through 2.5. The preceding  discussion of the
transaction between Knight and Fastway is qualified in its entirety by reference
to Exhibits 2.1 through 2.5 of this report.  Knight's  press release  announcing
the acquisition is attached hereto as Exhibit 99.
