IRP apportioned vehicles are vehicles registered under the International Registration Plan. Exempt vehicles are government vehicles, including schools buses that are owned or leased long-term by the government with the option to purchase; other government vehicles, including school buses that are only contracted by the government are not exempt.
Any vehicle traveling in the District and at least one other IRP jurisdiction that is used for the transportation of property, or persons for profit is defined as an apportioned vehicle. The apportioned vehicle is further characterized as a power unit:
- With a gross weight in excess of 26,000 pounds; or
- With three or more axles, regardless of weight; or
- Used in combination with another unit that together exceeds 26,000 pounds.
A carrier with power units that travel interstate, but do not meet the above weight or axle requirements, can choose to obtain an IRP registration but is not required to do so.
Semi-trailers, full trailers, and converter gear that travel into California are required to display a separate apportioned license tag and cab card.
Buses that have regular routes and are not used for transporting chartered parties are required to display a separate apportioned license tag and cab card. Buses (including chartered shuttle buses) used exclusively for chartered parties must either be registered in IRP, registered as a District vehicle, or operated with a trip permit while in the District of Columbia.
