This Post-Effective Amendment No. 1 to Form S-8 Registration Statement is being filed solely to remove from registration securities that were registered and will not be issued in connection with the Registrant's offering.

U.S. Xpress Enterprises, Inc., a Nevada corporation (the "Registrant"), filed its Registration Statement on Form S-8 (No. 333-105226) (the "Registration Statement") with the Securities and Exchange Commission with respect to 50,000 shares of the Registrant's Class A Common Stock, par value $0.01 per share (the "Class A Common Stock") that were to be issued in connection with the U.S. Xpress Enterprises, Inc. 2003 Non-Employee Directors Stock Award and Option Plan (the "Plan").

Following the Merger, no more shares of Class A Common Stock will be issued under the Plan.

Pursuant to the Registrant's undertaking in Part II, Item 9 in the Registration Statement, the Registrant is filing this Post-Effective Amendment No. 1 to the Registration Statement to withdraw the Registration Statement, including all exhibits to the Registration Statement, with respect to all unsold shares of Class A Common Stock registered under the Registration Statement.
