The International Registration Plan (IRP) is a registration reciprocity agreement among states of the United States, the District of Columbia and provinces of Canada providing for payment of apportionable fees on the basis of total distance operated in all jurisdictions.
IRP apportioned plates are required for any apportionable vehicle involved in inter-jurisdictional operations. An apportionable vehicle is defined as:
“Apportionable Vehicle” means (except as provided below) any Power Unit that is used or intended for use in two or more Member Jurisdictions and that is used for the transportation of persons for hire or designed, used, or maintained primarily for the transportation of property, and:
(i) has two Axles and a gross Vehicle weight or registered gross Vehicle weight in excess of 26,000 pounds (11,793.401 kilograms), or
(ii) has three or more Axles, regardless of weight, or
(iii) is used in combination, when the gross Vehicle weight of such combination exceeds 26,000 pounds (11,793.401 kilograms).
A Recreational Vehicle, a Vehicle displaying Restricted Plates, a bus used in the transportation of chartered parties or a government-owned Vehicle, is not an Apportionable Vehicle; except that a Truck or Truck Tractor, or the Power Unit in a Combination of Vehicles having a gross Vehicle weight of 26,000 pounds (11,793.401 kilograms), or less, and a bus used in the transportation of chartered parties, nevertheless may be registered under the Plan at the option of the Registrant.”
Fee does not include state fees and taxes.
