Tennessee truckers can get a major discount on the purchase of equipment that will save them fuel and keep air cleaner thanks to a program managed by the University of Tennessee.

Under the program, called Idle Smart, certain Tennessee truckers can receive a rebate for 50 percent, up to $4,000, of the cost of an Auxiliary Power Unit (APU). An APU decreases long engine idling while the trucker rests in the sleeping berth by providing cooling, heating and electrical power to class 8 trucks.

The university said in a news release that truckers using the discount can expect to save fuel immediately, and in a short time the savings will far outweigh the cost of the APU.
