Economics of Idling Reduction Options for Long-Haul Trucks

Many long-haul trucks still idle their engines overnight to provide “hotel load”—heating, cooling, and electricity for appliances—for drivers taking required rest periods in their sleeper cabs. Idling a truck engine for stationary power, however, uses a lot of fuel, accelerates engine wear, and produces harmful emissions. This fact sheet discusses the economics of idle reduction for long-haul trucks.
