The director is hereby authorized to design and to issue, under such rules as the director deems appropriate, distinctive identifying decals to be placed on the windshield of a custom vehicle at the time of registration designating the vehicle as a custom vehicle. Such decal shall be issued only upon receipt of a duly executed certificate in a format designated by the director indicating the year and make of the body that the custom vehicle resembles or was based upon and verifying that the vehicle is garaged and maintained in the state, that the vehicle is in fact a custom vehicle as defined in N.H. Rev. Stat. § 259:17-a, and that the vehicle is not intended for daily commuting use. A special fee in the amount of $15 shall be paid for the identifying decal. This special fee shall be in addition to the regular motor vehicle registration fee and shall be paid to the state treasurer and credited to the highway fund. Any state trooper or any individual who is authorized by the director to perform motor vehicle inspections provided by N.H. Rev. Stat. § 266:1, V is hereby authorized to perform the verification required by this section. A certificate of verification and decal issued under this section shall be transferable in the event the vehicle described by such certificate is sold or the ownership is otherwise transferred or conveyed. A vehicle displaying a custom vehicle identifying decal shall not be required to display a number plate on the front of the vehicle.
