Article 1 - Motor Vehicle Privilege Taxes
§ 27-19-81. Registration of vehicle in excess of weight limits; excess weight permits; excess size permits

This subsection shall apply, but not be limited to, any tractor, road roller or road machinery used solely and specifically in road building or other highway construction or maintenance work.
For each one thousand (1,000) pounds, or fractional part thereof, in excess of the weight authorized by Sections 63-5-29 and 63-5-33 for any such vehicle or in excess of the limits set by the Transportation Department for specified roads and bridges, the fee shall be Five Cents (5¢) per one thousand (1,000) pounds, or fractional part thereof, for each mile traveled upon the highways of the state, except that the fee for manufactured housing modular units, residential or commercial, shall be Two Cents (2¢) per one thousand (1,000) pounds, or fractional part thereof, for each mile traveled upon the highways of the state. Provided, however, no permit shall be issued for a fee of less than Ten Dollars ($10.00).
The Transportation Department may provide for an annual permit which will allow preapproved vehicles and loads to travel predesignated routes with self-issued permits. Under such self-issuance authority, the owner of the vehicle shall complete the permit in a format designated by the department, electronically transmit a copy to the department prior to the move, and ensure that a copy is in the possession of the operator. Vehicles having a gross weight exceeding the limits provided by law that have a nondivisible gross vehicle weight of ninety-five thousand (95,000) pounds or less, which are otherwise legal, shall not be restricted as to the hours of the day such vehicles may be operated on predesignated routes. The department shall bill the vehicle owner according to the provisions of the preceding paragraph. The department is authorized to modify predesignated routes at any time for cause, such as highway construction or hazardous highway conditions. The annual fee for the self-issuance permit authority obtained pursuant to this paragraph shall be Five Hundred Dollars ($500.00) per owner, regardless of the number of vehicles which he will operate pursuant to such permit, in addition to any other fees required by this section. Any vehicle and load being operated pursuant to this paragraph for which the operator does not have the permit or a copy thereof in his possession, or for which a copy of the permit was not electronically transmitted to the department, shall be deemed not to have a permit and shall be penalized accordingly.
It shall not be necessary for the owner or operator of a vehicle to obtain a permit pursuant to this subsection if such owner or operator has obtained for his vehicle an annual special permit for vehicles transporting heavy equipment pursuant to Section 63-5-52.
