About this data
This post is compiled by the America’s Driving Force team from the FMCSA Motor Carrier Census, a public U.S. Department of Transportation dataset, retrieved September 29, 2026. Carriers are counted by the physical address on their federal record, so a national carrier appears under its home state. Truck and driver counts and cargo types are self-reported. School bus, waste, towing, taxi and limousine operators, railroads and truck-rental fleets are excluded, and the table above shows companies whose names indicate a transportation business.
