Also known as: Participating States

Definition

UCR participating states are the states that have joined the Unified Carrier Registration Agreement and collect UCR fees directly. Most states participate. Carriers based in a participating state register through that state as their base state. The 41 participating states share UCR revenue under a formula set by the UCR Plan board to fund commercial-vehicle safety enforcement. Carriers based in one of the ten non-participating jurisdictions select the nearest participating state as their base state instead. The fee is identical in every state, and UCR is paid only once, to that single base state.
