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 changed very little over the past twenty years. Consequently, the gallons of fuel consumed doubled between 1980 and 2003 along with the number of miles traveled.
