66-3-22. Re-registration; change in declared gross weight.
A. Any vehicle or combination registered at a declared gross weight may be re-registered at a higher weight upon payment of the difference between the paid registration fee and the new registration fee. The amount shall be prorated on a quarterly basis, with any fraction of a quarter-year to be considered a full quarter. In no event shall the amount be less than five dollars ($5.00).
B. When a vehicle or combination has been altered, or from which equipment has been removed to meet legal requirements, and thus will not operate at the current declared gross weight, the registrant may apply for a lowering of the declared gross weight. Upon approval, the registrant shall be refunded a sum equal to the difference between the fee paid for the current registration period and the revised registration fee for the same period, multiplied by the fraction of the whole period remaining, calculated on the basis of the number of complete quarter-years remaining after the date of the application for changed registration.
