Figure 3-9. Share of Highway Vehicle-Miles Traveled by Vehicle Type: 2011
Despite doubling over the past two decades, truck traffic remains a relatively small share of highway traffic as a whole. In 2011, commercial trucks accounted for about 9 percent of highway vehicle-miles traveled. Truck tractors hauling semitrailers and other truck combinations accounted for approximately 63 percent of commercial truck travel, while single-unit trucks with six or more tires accounted for the remainder.

Notes:
Based on a new methodology, FHWA revised its annual vehicle miles traveled, number of vehicles, and fuel economy data beginning with 2007. Information on the new methodology is available at www.fhwa.dot.gov/policyinformation/statistics.cfm. Data in this figure should not be compared to those in pre-2011 editions of Freight Facts and Figures.
