History of trucking in America

About 1.7 million truckers drive heavy-duty and tractor-trailer trucks in the United States. Overall, the industry supports 7.4 million jobs. In 29 states—more than half the country—“truck driver” is the dominant occupation, and for good reason. More than 70% of the 10.5 billion tons of freight delivered annually in the United States travels by truck. But the industry is more than just a massive job provider and a critical component of American society: It’s also an economic canary in a coal mine.
