Fuel Fact of the Week

Fact #1101: Medium/Heavy Trucks Were 4% of the Vehicle Population but Accounted for 26% of Fuel Use in 2017



Trucks in the medium/heavy truck category include tractor trailers, also known as combination trucks, and single-unit trucks. In the most recent year for which data are available, combination trucks made up only 1% of the truck population but were responsible for 6% of all vehicle miles traveled (VMT) and 17% of vehicle fuel use. Single-unit trucks were 3% of the truck population and 3% of VMT, while making up 9% of vehicle fuel use.

While alternative fuel vehicle (AFV) fuel economy testing is largely similar to that of conventional fuels, the EPA makes some adjustments to account for different vehicle technology and fuel energy content. By tailoring AFV fuel economy testing and reporting, the EPA is able to provide apples-to-apples comparisons and allow consumers to make informed decisions.
