Figure 3-6. Share of Highway Vehicle Miles Traveled by Vehicle Type: 2009

Despite doubling over the past two decades, truck traffic remains a relatively small share of highway traffic as a whole. In 2009, commercial trucks accounted for about 10 percent of highway vehicle miles traveled. Truck tractors hauling semitrailers and other truck combinations accounted for approximately 58 percent of commercial truck travel, while single-unit trucks with six or more tires accounted for the remainder.
