IRP Registration

Who is required to register under the IRP?
Answer: Apportioned vehicles must be registered under IRP.


You may have questions regarding IRP registration, that is why you should take the time to do some basic research on IRP registration.

The text in grey below is the official text that explains the requirements and what makes you eligible for IRP registration.

The Plan defines an apportionable vehicle as: any vehicle 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).

Exceptions: Recreational vehicles, vehicles displaying restricted plates, buses used in the transportation of chartered parties, or government-owned vehicles. Effective January 1, 2016 chartered buses will no longer be exempt from IRP Registration.

Optional: Trucks or truck tractors, or combinations of vehicles having a gross vehicle weight of 26,000 pounds (11,793.401 kilograms), or less, and buses used in the transportation of chartered parties, may be registered under the Plan at the option of the Registrant.

In most cases trucks that go interstate will need IRP plates and an IFTA account. If you do only interstate or local dray-age then you will not need to go through the IRP registration process.

Are trailers and semi-trailers required to be apportioned?
Answer No, the Plan does not require the apportionment of trailers.

Section 515 of the Plan states “A Trailer, Semi-Trailer, or Auxiliary Axle properly registered in any Jurisdiction shall be granted full and free Reciprocity.”
