Exhibit 99.1

                                 August 7, 2002


STATEMENT UNDER OATH OF PRINCIPAL EXECUTIVE OFFICER AND PRINCIPAL FINANCIAL
OFFICER REGARDING FACTS AND CIRCUMSTANCES RELATING TO EXCHANGE ACT FILINGS

I, William D. Zollars, Chairman, President and Chief Executive Officer of Yellow
Corporation, state and attest that:

(1)  To the best of my knowledge, based upon a review of the covered reports of
     Yellow Corporation, and, except as corrected or supplemented in a
     subsequent covered report:

     -    no covered report contained an untrue statement of a material fact as
          of the end of the period covered by such report (or in the case of a
          report on Form 8-K or definitive proxy materials, as of the date on
          which it was filed); and

     -    no covered report omitted to state a material fact necessary to make
          the statements in the covered report, in light of the circumstances
          under which they were made, not misleading as of the end of the period
          covered by such report (or in the case of a report on Form 8-K or
          definitive proxy materials, as of the date on which it was filed).

(2)  I have reviewed the contents of this statement with Yellow Corporation's
     audit committee.

(3)  In this statement under oath, each of the following, if filed on or before
     the date of this statement, is a "covered report":

     -    2001 Annual Report on Form 10-K of Yellow Corporation;

     -    all reports on Form 10-Q, all reports on Form 8-K and all definitive
          proxy materials of Yellow Corporation filed with the Commission
          subsequent to the filing of the Form 10-K identified above; and

     -    any amendments to any of the foregoing.
