Vermont Apportioned Registration Plan (IRP)
The International Registration Plan (IRP) is a registration reciprocity agreement between all jurisdictions (except Alaska & Hawaii) of the United States and several Canadian provinces for payment of registration fees for highway transport vehicles. The fee is based on fleet miles operated in member jurisdictions.
The unique feature of this plan is that even though registration fees are paid to member jurisdictions in which fleet vehicles are operated, only one state issues the plates and cab cards for each fleet vehicle when registered under the plan. A fleet vehicle is an apportionable vehicle and this vehicle, so far as registration is concerned may be operated both interstate and intrastate.
It is the purpose of this program to promote and encourage the fullest possible use of the highway system by authorizing the proportional registration of fleets of vehicles and recognition of vehicles proportionally registered in other jurisdictions, thus contributing to the economic and social development and growth of the jurisdiction.
Under the IRP program the interstate carrier is required to file an application with the jurisdiction in which the carrier is based. The base jurisdiction issues a base “apportioned” license plate and cab card. The base plate and cab card are the registration credentials required to qualify the carrier to operate interstate for intrastate in member jurisdictions. The cab card will list those jurisdictions to which the operator has paid apportioned registration fees. The base jurisdiction collects the registration fees (“apportioned fees”) for each jurisdiction at one time and divides them among the other jurisdictions according to mileage traveled in each state.
Apportioned Registration Does Not:
- waive, or exempt a truck operator from, obtaining authority from an State/Province in which the apportioned vehicle travels (either inter or intra); or
- waive, or replace the requirements of the International Fuel Tax Agreement (IFTA); or
- waive, or exempt the payment of reporting of other taxes (income tax, sales tax, etc.); or
- allow registrants to exceed the maximum length, width, height or axle limitations; or
- allow registrants to violate “bridge laws”; or
- waive, or exempt the payment or reporting of the Federal Heavy Vehicle Use Tax (Form 2290)
