Interstate Commerce
By Korey Sharp-Paar · Reviewed by the Fast Trucking Compliance team
Definition
Interstate commerce is commercial transportation that crosses state lines, or that begins or ends in a different state from where the freight or carrier is based. It is the trigger for federal FMCSA oversight: a USDOT number, UCR registration, operating authority for for-hire carriers, and federal safety compliance. Carriers operating only within one state fall under state - not UCR - jurisdiction. A purely intrastate carrier does not owe UCR; hauling a single interstate load brings it into the federal system. Every motor carrier operating in interstate commerce must file UCR annually, with the fee scaled to power-unit count.

Who Needs UCR? Who Must Register (and Who’s Exempt)You need UCR if you run interstate as a motor carrier (for-hire or private), freight forwarder, broker, or leasing company. 49 CFR 367.50 names all four; intrastate-only is exempt.
