                            RULE 12B-25 (B) AND (C)

     If the subject report could not be filed without unreasonable effort or
expense and the registrant seeks relief pursuant to Rule 12b-25(b), the
following should be completed. (Check box if appropriate)

/X/  (a)  The reasons described in reasonable detail in Part III of this form
          could not be eliminated without unreasonable effort or expense;

/ /  (b)  The subject annual report, semi-annual report, transition report on
          Form 10-K, 10-KSB, 20-F, 11-K or Form N-SAR, or portion thereof will
          be filed on or before the 15th calendar day following the prescribed
          due date; or the subject quarterly report or transition report on Form
          10-Q, 10-QSB, or portion thereof will be filed on or before the fifth
          calendar day following the prescribed due date; and

                                   PART III.
                                   NARRATIVE

     State below in reasonable detail the reasons why Form 10-K, 10-KSB, 11-K,
20-F, 10-Q, 10-QSB, N-SAR or the transition report portion thereof could not be
filed within the prescribed time period. (Attach extra sheets if needed.)

Wabash National Corporation ("Wabash") could not file its Form 10-K for the
period ended December 31, 2001, in a timely manner due to extensive negotiations
with its banks and senior noteholders for refinancing of its revolving line of
credit and senior notes. Wabash anticipates that closing on the refinancing
will occur by April 15, 2002 at which time Wabash expects to be in a position
to file its Form 10-K.

                                    PART IV.
                               OTHER INFORMATION


     (1) Name and telephone number of person to contact in regard to this
notification.

Mark R. Holden                           765                      771-5300
-------------------------------------------------------------------------------
     (Name)                          (Area Code)             (Telephone Number)


     (2) Have all other periodic reports required under Section 13 or 15(d) of
the Securities Exchange Act of 1934 or Section 30 of the Investment Company Act
of 1940 during preceding 12 months or for such shorter period that the
registrant was required to file such report(s) been filed? If the answer is no,
identify report(s).
                                                               /X/ Yes / / No


     (3) Is it anticipated that any significant change in results of operations
from the corresponding period for the last fiscal year will be reflected by the
earnings statements to be included in the subject report or portion thereof?

                                                               /X/ Yes / / No


     If so: attach an explanation of the anticipated change, both narratively
and quantitatively, and, if appropriate, state the reasons why a reasonable
estimate of the results cannot be made.

As previously announced by Wabash in its press release on March 5, 2002, the
change in results of operations for fiscal year 2001 from fiscal year 2000 is a
result of 1) substantial charges associated with the completion of Wabash's
previously announced restructuring activities, including the divestiture of
international operations, accelerated sales efforts to normalize used trailer
inventory levels and significant reductions in headcount; 2) certain charges
that may be associated with Wabash's failure to be in compliance with its credit
facilities at year end; 3) the impact on business and economic fundamentals
during the fourth quarter as a result of the events of September 11, 2001, the
ongoing economic recession and the resultant industry-wide downturn; and 4)
charges associated with the continued effects of past legacy business practices.
As announced on March 5, 2002, the following are the results Wabash anticipates
reporting in the Form 10-K: For the year ended December 31, 2001, net sales
were $863.4 million compared to $1.3 billion for 2000. Net loss for fiscal year
2001 is $232.2 million, compared to a net loss of $6.7 million in 2000. Diluted
loss per share is ($10.17) for the fiscal year ended December 31, 2001, compared
to ($0.38) in 2000. These results are subject to the completion of the
definitive agreements between Wabash and its banks and senior noteholders.
