Motor Carrier Services
International Registration Plan
|NOTICE TO ALL MOTOR CARRIERS: ADOT has transitioned to a new and improved processing system for our motor
carriers that integrates interstate vehicle registration (IRP) and interstate
fuel tax (IFTA) services. An official letter was mailed to all IRP/IFTA
carriers with an overview of this exciting implementation. Read the letter now. |
The International Registration Plan (IRP) is an agreement between member jurisdictions for registering vehicles that travel in two or more jurisdictions. The member jurisdictions include all contiguous states, the District of Columbia and participating Canadian provinces. Registrations issued under this agreement are commonly referred to as "apportioned" or "prorated" registrations.
Apportioned registration is an optional method of registration that provides for registration of a fleet of vehicles that operate in two or more jurisdictions, by payment of fees to the base jurisdiction. A fleet can include one or more vehicles. The base jurisdiction is responsible for transmitting the fees owed to the affected jurisdictions. Registration fees are determined by the percentage of miles traveled in each member jurisdiction and the registered combined gross vehicle weight rating (GVWR) of each vehicle.
The Full Reciprocity Plan (FRP), which became effective Jan. 1, 2015, has made the Plan more efficient, more equitable and more flexible for its member jurisdictions and registrants by granting full reciprocity for all apportioned vehicles in all member IRP jurisdictions and removing from the Plan any provisions related to estimated distance. First time registrants are registered in all member jurisdictions; therefore, allowing them the opportunity to travel in any of the participating jurisdictions. However, registrants will only pay fees to those jurisdictions where distance was accrued during the fleet's reporting period.
