Under IRP, an interstate carrier files an application with the jurisdiction in which it is based. That jurisdiction is known as the base jurisdiction. IRP allows the base jurisdiction to collect the registration fees for the other IRP jurisdictions. Fees are based upon mileage and weight information submitted by the carrier. The base jurisdiction issues a set of Apportioned Plates and a Cab Card for each vehicle. The Cab Card lists all IRP jurisdictions and the corresponding weights that the carrier has requested.
