61-3-716. Proportional registration of fleet motor vehicles. (1) If a jurisdiction permits or requires the licensing of fleets of motor vehicles, trailers, semitrailer, or pole trailers in interstate or combined interstate and intrastate commerce and payment of registration fees, license fees, taxes, or other fixed fees on those motor vehicles, trailers, semitrailers, or pole trailers on an apportionment basis commensurate with and determined by the miles traveled on and the use made of the jurisdiction's highways as compared with the miles traveled on and the use made of other jurisdiction's highways or any other equitable basis of apportionment and if the jurisdiction exempts motor vehicles, trailers, semitrailers, or pole trailers registered in any other jurisdiction under this apportionment basis from the requirements of full payment of its own registration, license fees, taxes, or other fixed fees, then the department may, by agreement, adopt exemptions with respect to motor vehicles, trailers, semitrailers, or pole trailers of these fleets, whether owned by residents or nonresidents of this state and regardless of where they are based. An agreement, under the terms, conditions, or restrictions that the department considers proper, may provide that owners of motor vehicles, trailers, semitrailers, or pole trailers operated in interstate or combined interstate and intrastate commerce in this state be permitted to pay registration, license fees, taxes, or other fixed fees on an apportionment basis commensurate with and determined by the miles traveled on and the use made of the highways of this state as compared with the use made of the highways of other jurisdictions or any other equitable basis of apportionment. This agreement may not authorize or be construed to authorize a motor vehicle, trailer, semitrailer, or pole trailer so registered to be operated in intrastate commerce in this state unless the owner of the motor vehicle, trailer, semitrailer, or pole trailer has been granted intrastate authority or rights by the public service commission if a grant is otherwise required by law.

(2) The department of transportation may adopt rules that it considers necessary to carry out and administer this section, and the registration of fleet motor vehicles, trailers, semitrailers, or pole trailers under 61-3-711 through 61-3-733 is subject to the rights, terms, and conditions granted by or contained in any applicable agreement, arrangement, or declaration made by the department. The department of transportation shall adopt rules providing for a change of registration period for a fleet in a case in which the owner of the fleet requests that the registration period be changed to coincide with the registration period of one or more other fleets in the same ownership.
