What It Means for Carriers

  • If your principal place of business is in one of the participating states, you register your UCR through your home base state.  

  • If you are based in a non-participating state, you still must comply with UCR if you operate interstate commerce. You’ll need to select a participating state as your base state and file/ pay UCR ther.

  • Being in a non-participating state does not exempt you from UCR. The requirement is federal for interstate operations.  

  • For enforcement: during roadside inspections, authorities can check whether the carrier has valid UCR registration regardless of the state of operation.
