Idle Reduction Weight Exemption

A vehicle equipped with idle reduction technology may exceed the state's gross, axle, and bridge vehicle weight limits by up to 500 pounds to compensate for the additional weight of the idle reduction technology. The additional weight may not exceed the actual weight of the idle reduction unit. The vehicle operator must carry written certification showing the weight of the technology and must be able to demonstrate or certify that the unit is fully functional.
