I, Gregory L. Quesnel, certify that:

  1.   I have reviewed this quarterly report on Form 10-Q of CNF Inc.;

  2.   Based on my knowledge, this report does not contain any untrue
     statement of a material fact or omit to state a material fact necessary
     to make the statements made, in light of the circumstances under which
     such statements were made, not misleading with respect to the period
     covered by this report;

  3.   Based on my knowledge, the financial statements, and other
     financial information included in this report, fairly present in all
     material respects the financial condition, results of operations and
     cash flows of the registrant as of, and for, the periods presented in
     this report;

  4.   The registrant's other certifying officers and I are responsible
     for establishing and maintaining disclosure controls and procedures (as
     defined in Exchange Act Rules 13a-15(e) and 15d-15(e)) for the
     registrant and have:

       a.   designed such disclosure controls and procedures, or caused such
          disclosure controls and procedures to be designed under our
          supervision, to ensure that material information relating to the
          registrant, including its consolidated subsidiaries, is made known to
          us by others within those entities, particularly during the period in
          which this quarterly report is being prepared;

       b.   evaluated the effectiveness of the registrant's disclosure
          controls and procedures and presented in this report our conclusions
          about the effectiveness of the disclosure controls and procedures, as
          of the end of the period covered by this report based on such
          evaluation; and

       c.   disclosed in this report any change in the registrant's
         internal control over financial reporting that occurred
         during the registrant's most recent fiscal quarter (the
         registrant's fourth fiscal quarter in the case of an annual
         report) that has materially affected, or is reasonably likely
         to materially affect, the registrant's internal control over
         financial reporting; and

  5.   The registrant's other certifying officers and I have disclosed,
     based on our most recent evaluation of internal control over financial
     reporting, to the registrant's auditors and the audit committee of
     registrant's board of directors (or persons performing the equivalent
     functions):

       a.   all significant deficiencies and material weaknesses in the design
          or operation of internal controls over financial reporting which are
          reasonably likely to adversely affect the registrant's ability to
          record, process, summarize and report financial information; and

       b.   any fraud, whether or not material, that involves management or
          other employees who have a significant role in the registrant's
          internal controls over financial reporting.
