Idle Reduction Technologies for Trucks

A large amount of truck idling occurs at travel centers while truckers rest during layover periods. Engines are idled to maintain comfortable temperatures while resting or to provide power for televisions, refrigerators, microwaves, etc. Technologies are available that can provide for these needs without engine idling. Examples of these fuel saving technologies are:

  • Automatic Shut Down/Start Up Systems - electronic diesel engine shut down after a set time period.
  • Battery - keeps the inside of a vehicle cab warm in the winter or cool in the summer.
  • Auxiliary Power Unit or Generator Set - provides heat and air conditioning for the cab.
  • Electrified Parking Spaces - electric shore power connectivity can provide heat, air conditioning, and electrical power without requiring the engine of the truck to idle.

SmartWay Transport Partnership


Truck technologies that save fuel or use fuel more efficiently can pay for themselves through fuel savings. The EPA SmartWay calculator helps truck owners and fleet owners compare the costs and estimate the fuel savings associated with various efficiency technologies.
