      2.   Such vehicle is used exclusively in intercity or interstate commerce.
   B.   No license shall be required by this title of any person whose only business activity in the city is the mere delivery in the city of property sold by him at a regular place of business maintained by him outside the city where:
      1.   Such person's business is at the time of such delivery licensed by the Utah municipality or county in which such place of business is situated; and
      2.   The authority licensing such business grants to licensees of the city making deliveries within its jurisdiction the same privileges, upon substantially the same terms, as are granted by this section; and

Such plate or symbol shall identify the licensing authority by which it is issued, shall indicate that it evidences a license issued thereby, and shall specify the year or term for which it is effective.
   C.   The city recorder shall, at the request of any person, certify a copy of this section to any municipality or county of the state to which a copy has not previously been certified. (1989 Code § 9-123)
