International Registration Plan (IRP)

The International Registration Plan (IRP) is a special plan or a reciprocity agreement between member states and member jurisdictions for registering vehicles that must travel in 2 or more member-states with one member state, the member state where the vehicle is based. A jurisdiction may be a state or a Canadian province. The base member state issues 1 apportioned license plate and cab card for each vehicle. 

There are penalties and fines for lapse of insurance coverage, registration suspension, and reinstatement processes.
