UCR Base-State Rule
Also known as: Base-State Rule, Base-State Selection Rule
By Korey Sharp-Paar · Reviewed by the Fast Trucking Compliance team
Definition
The UCR base-state rule determines which state collects your UCR fee. A carrier registers in its home state when that state participates in UCR. When the home state is non-participating, the carrier must choose the geographically nearest participating state. Fees are paid only to that one base state - UCR is never paid state-by-state - and the resulting registration is recognized in all 50 states. The non-participating jurisdictions are Arizona, Florida, Hawaii, Maryland, Nevada, New Jersey, Oregon, Vermont, Wyoming, and the District of Columbia. Being based in one of them never exempts a carrier from UCR.
