29- 250 C.M.R. ch. 162, § 2
This rule establishes and defines Maine's participation in the International Registration Plan (IRP). The IRP is a registration prorate agreement that provides for the proportional registration of commercial motor vehicles used in interstate operation.
The IRP is an agreement among member states and provinces. The agreement is administered by IRP Inc., and is governed by a Board of Directors consisting of representatives from member jurisdictions.
The IRP provides for base jurisdiction registration; a single registration plate and registration cab card for each vehicle; and the payment of proportional registration fees based on the percentage of miles the registrant operated in each member jurisdiction. The registrant is permitted to operate in intrastate as well as in interstate commerce in each member jurisdiction.
Since each registrant pays a proportional share of each member jurisdiction's registration fee, registration bills will be different for each registrant. Each member jurisdiction transmits the appropriate revenue to the other member jurisdictions.
Mileage reporting and fee calculations are done on a fleet basis. A fleet is one or more apportionable vehicles sharing a common operational profile.
