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

In contrast to single-unit trucks, the average fuel consumption of combination trucks has not changed over the past twenty years. Consequently, the gallons of fuel consumed have doubled between 1980 and 2002 along with the number of miles traveled.
