Reports, Trends & Statistics

The trucking industry is the lifeblood of the U.S. economy. Over 70% of all the freight tonnage moved in the U.S. goes on trucks. Without the industry and our truck drivers, the economy would come to a standstill.

It also takes over 38 billion gallons of diesel fuel to move all of that freight. Simply – without trucks, America stops.
