Tables 5-9 and 5-9M. Combination-Truck Fuel Consumption and Travel: 1980-2005

In contrast to single-unit trucks, miles per gallon by combination trucks (based on total travel and fuel consumption) increased by only 11 percent over the past 25 years. Consequently, the gallons of fuel consumed increased by nearly 87 percent, and miles traveled more than doubled between 1980 and 2005.
