IRP is a method of registering fleets of vehicles that travel in two or more member jurisdictions. Most states in the U.S. and Canadian provinces are members of the plan.

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 people for hire or designed, used or maintained primarily for the transportation of property, and:

  • has two axles and a gross vehicle weight or registered gross vehicle weight in excess of 26,000 pounds (11,793.401 kilograms), or
  • has three or more axles, regardless of weight, or
  • is used in combination, when the gross vehicle weight of such combination exceeds 26,000 pounds (11,793.401 kilograms).

Recreational vehicles, vehicles displaying restricted plates, SUV's, passenger vans and government-owned vehicles are not apportionable vehicles.

Trucks or truck tractors, or the power units in a combination of vehicles having a gross vehicle weight of 26,000 pounds or less, and buses used in the transportation of chartered parties are not required to register; however, they may be registered under the Plan at the option of the Registrant.

Base Jurisdiction means the member jurisdiction, selected in accordance with Section 305, to which an applicant applies for apportioned registration under the plan or the member jurisdiction that issues apportioned registration to a registrant under the plan.  Refer to basing requirements.
