Natural Gas Vehicle (NGV) Weight Exemption

A vehicle powered primarily by natural gas may exceed the state's gross, single axle, tandem axle, or bridge formula weight limits by an amount equal to the difference of the weight of the natural gas tank and fueling system and the weight of a comparable diesel tank and fueling system, up to 2,000 pounds. Upon request, the vehicle operator must provide documentation that verifies the weight of the natural gas fueling system. (Reference South Carolina Code of Laws 56-5-4160(M))
