Natural Gas and Electric Vehicle Weight Exemption

A vehicle primarily powered by natural gas or electric battery power may exceed the state’s gross vehicle weight limits by a weight equal to the difference between the weight of the vehicle with the natural gas tank and fueling system or the weight of the vehicle with the electric battery power system and the weight of a comparable vehicle with a diesel tank and fueling system. The maximum gross weight may not exceed 82,000 pounds.
