UCR Enforcement
Also known as: Roadside Enforcement
By Korey Sharp-Paar · Reviewed by the Fast Trucking Compliance team
Definition
UCR enforcement is how UCR compliance is checked: state troopers and commercial-vehicle inspectors verify a carrier's current-year UCR against the national database at roadside inspections and weigh stations, primarily in participating states. The consequences of a missing UCR are set by each state. Enforcement for a registration year begins January 1. FMCSA does not directly revoke MC or USDOT authority for a missed UCR. State fines for operating without a valid UCR are separate from the UCR fee itself, which still must be paid, and there is no separate federal late penalty.
