Interstate vs intrastate commerce: what counts?

Interstate commerce means transporting goods or passengers across state lines — or hauling freight that is part of a journey that crosses state lines, even if your truck only drives within one state. Intrastate commerce means movement that starts and ends within the same state with no interstate connection.

Why it matters

Federal DOT regulations — including USDOT registration, operating authority, and UCR — generally apply to interstate commerce. Intrastate operations may be regulated by the state instead of FMCSA, and requirements vary by state. If you're not sure which category your operation falls into, assume interstate until you confirm otherwise.

The interstate connection rule

Freight that originates out-of-state, is unloaded at a warehouse, and then picked up by a local truck for the last mile is often still considered interstate commerce — even though the second truck never crossed a state line. The original intent of the shipment determines the classification, not just the truck's path.

Mixed operations

Many carriers do both. If any part of your operation involves interstate commerce, the federal requirements apply to the whole operation. Keeping separate fleets or distinct operations doesn't always separate the regulatory treatment.
