Tables 5-9 and 5-9M. Combination Truck Fuel Consumption and Travel

In contrast to single-unit trucks, miles traveled per gallon by combination trucks increased by only 12 percent over the past twenty years. Consequently, the gallons of fuel consumed increased by nearly 90 percent between 1980 and 2004 along with a doubling of miles traveled.
