Idle Reduction and Natural Gas Vehicle (NGV) Weight Exemption

Any motor vehicle equipped with an auxiliary power unit or other idle reduction technology may exceed the gross, single axle, tandem axle, or bridge formula weight limits by up to 550 pounds (lbs.) to compensate for the added weight of the idle reduction technology. Furthermore, any NGV may exceed the limits by up to 2,000 lbs. To be eligible for the weight exemption, the vehicle operator must be able to provide written proof idle reduction technology weight and demonstrate or certify that it is fully functional at all times.
