     RE:  Registration Statement on Form S-1 -
          230,000 Shares of Class A Common Stock Relating to an Increase in
          Shares Offered Pursuant to Registration No. 333-20019
          ------------------------------------------------------

Ladies and Gentlemen:

     Scudder Law Firm, P.C. has served as legal counsel to Simon Transportation
Services Inc., a Nevada corporation (the "Company"), in the preparation and
filing with the Securities and Exchange Commission of the Company's Registration
Statement on Form S-1 dated January 17, 1997, Registration No. 333-20019 (the
"Original Registration Statement").

     We also served as legal counsel to the Company in connection with the
preparation and filing of a registration statement filed by the Company pursuant
to Rule 462(b) under the Securities Act (the "Additional Registration
Statement"). The Additional Registration Statement covers the registration of
230,000 additional shares (30,000 subject to the underwriters' over-allotment
option) of the Company's Class A Common Stock (the "Additional Shares") for sale
by Richard D. Simon, the principal selling stockholder under the Original
Registration Statement.

     In connection with the following opinion, we have examined and have relied
upon such documents, records, certificates, statements, and instruments as
we have deemed necessary and appropriate.

     Based upon the foregoing, it is our opinion that the Additional Shares of
Class A Common Stock, when and if sold in the manner set forth in the Additional
Registration Statement, will be legally and validly issued, fully paid, and
nonassessable.

     The undersigned hereby consents to the filing of this opinion as Exhibit 5
to the Additional Registration Statement and the use of its name in the
Additional Registration Statement under the caption of the prospectus entitled
"Legal Matters" and elsewhere it may appear.

                                       Very truly yours,

                                       Scudder Law Firm, P.C.


                                       By:  /s/ Mark A. Scudder
