A vehicle equipped with qualified idle reduction technology may exceed the state's gross and axle weight limits by up to 400 pounds (lbs.) to compensate for the additional weight of the idle reduction technology. A vehicle primarily powered by natural gas 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 and the weight of a comparable vehicle with a diesel tank and fueling system. Any NGV may exceed the limits by up to 2,000 lbs.
