Heavy-duty truck drivers can choose from a variety of equipment to reduce idle time and save fuel. Argonne National Laboratory estimates that more than one million long-haul heavy-duty trucks idle during required rest stops every day. Reducing the amount of fuel consumed during idling can provide significant cost savings. In addition, many idle reduction technologies can improve driver comfort through improved climate control, support for lighting and electronics, better air quality, and reduced noise levels. See the fact sheet, Long-Haul Idling Burns Up Profits for more information.

Idle Reduction Equipment

Technologies to reduce idling include:

IdleBox contains the Compendium of Idling Reduction Equipment for Class 1-8 Vehicles, a database of known, currently available idling reduction equipment, the services provided (e.g., engine shut-off, heating, cooling, electric power, cargo refrigeration), and more. The U.S. Environmental Protection Agency’s (EPA) Clean Diesel Program provides financial support for some idle reduction projects. The program includes grants and rebates funded under the Diesel Emissions Reduction Act (DERA). EPA's SmartWay Program offers a list of Verified Idle Reduction Technologies.
