Figure 2-1: Highway Vehicle-Miles Traveled: 1980 to 2002

As the demand for goods and services grows, so does the amount of truck traffic on the nation's highways. Commercial truck travel has doubled over the past two decades, about the same as highway travel as a whole. Consequently, truck vehicle miles traveled (VMT) as a share of all VMT has remained relatively stable. Over this period, the use of combination trucks travel grew slightly faster than single unit trucks.
