What Are Apportioned Plates?
Apportioned plates are license plates that are issued to commercial vehicles that are operated in two or more jurisdictions and have a gross vehicle weight of over 26,000 pounds. The plates are usually marked “Apportioned,” “APP” or “PRP.”
Apportioned license plates are issued under the International Registration Plan, which is a cooperative agreement between the United States and Canada. Under the agreement, the base, or home, jurisdiction collects vehicle registration fees, which are then apportioned among the states or provinces that the vehicle travels through, depending on the total distance operated in each jurisdiction. The base jurisdiction issues the vehicle with a set of apportioned license plates and a cab card outlining the jurisdictions where the vehicle is allowed to operate.
