Fact #627: June 14, 2010
Idle Reduction for Heavy Trucks
In order to encourage the use of idling reduction devices in large trucks, the Energy Policy Act of 2005 allowed for a 400-pound weight exemption for the additional weight of idling reduction technology. States were given the discretion of adopting this exemption without being subjected to penalty.
Since then, most States have passed laws which allow trucks to exceed the maximum gross vehicle weight limit by an additional 400 lbs (white States) Other States have a 400 lb weight allowance which is granted by enforcement personnel (light blue States). Four States have legislation pending at this time (green States) and another four States have not adopted the weight exemption.
An additional incentive for equipping large trucks with idle reduction technologies was in the Energy Improvement and Extension Act of 2008. The Act excludes certain idling reduction devices and advanced insulation from Federal excise taxes. Products which are eligible for the tax exemption include:
- fuel operated heaters,
- battery air conditioning/heating systems,
- auxiliary power units/generator sets,
- thermal storage systems, and
- shore connection systems
