All IRP member jurisdictions have agreed to allow one jurisdiction to collect the registration fees (apportioned fees) for each jurisdiction at one time. These fees are then distributed among the other IRP jurisdictions according to the percentage of miles traveled in each jurisdiction.
Truck Information. IRP allows motor carriers to proportionally register their vehicles for states in which they operate such that they are not required to obtain separate registrations for each state. IRP registration fees are based upon the proportional mileage operated in each state. The IRP program applies to vehicles which are operated through Pennsylvania and are used for the transportation of persons for hire or are designated, used, or maintained primarily for transportation of property.
