Tables 2-10 and 2-10M: U.S. Hazardous Materials Shipments by Transportation Mode: 2002

Trucks move more than one-half of all hazardous materials shipped from a location in the United States. However, truck ton-miles of hazardous shipments account for a much smaller share, about one-third of all ton-miles, because such shipments travel relatively short distances. By contrast, rail accounts for only 5 percent of shipments by weight but 22 percent by ton-miles.
