What states are NOT in the UCR plan?
Nine states plus the District of Columbia do not participate as base states under UCR: Arizona, Florida, Hawaii, Maryland, Nevada, New Jersey, Oregon, Vermont, and Wyoming, plus D.C. Carriers based in these jurisdictions route their UCR registration through the nearest participating state. The receipt is valid in all 50 states regardless of base.
The 41 participating states plus the 10 non-participating jurisdictions (9 states + D.C.) make up the UCR plan. Non-participating jurisdictions do not collect UCR fees from carriers based there but their carriers still need to register (through a participating state of their choice).
Non-participating jurisdictions: Arizona, Florida, Hawaii, Maryland, Nevada, New Jersey, Oregon, Vermont, Wyoming, and the District of Columbia. Maine, Massachusetts, New Hampshire, Oklahoma, and Rhode Island all participate - check plan.ucr.gov/participating-states for the current roster before relying on any list.
For a Florida-based carrier: UCR registration routes through Georgia, South Carolina, or another nearby participating state. The fee structure is the same as any other base state. The receipt is valid for operation in all 50 states.
Operating in a non-participating state does not require UCR enforcement - those states don't check at roadside as part of UCR. Operating in a participating state without current UCR exposes the carrier to enforcement (OOS orders, fines).
