What license plates do International Registration Plan (IRP) vehicles display?

International Registration Plan (IRP) vehicles display California Apportioned Plates because these plates are specifically designed for commercial vehicles that operate in multiple jurisdictions. The IRP is an agreement among U.S. states and Canadian provinces that allows for the registration of these vehicles based on the miles traveled in each jurisdiction.

Apportioned plates facilitate the process of registration by allowing a single license plate to cover all states where the vehicle operates, based on the percentage of mileage in each state, rather than requiring separate registrations and plates for each state. This system streamlines the registration process, reduces paperwork, and eliminates the need for individual state-specific plates for a vehicle that travels across state lines.

In contrast, standard California plates are used for typical passenger vehicles and do not account for multi-state travel. Custom multi-jurisdiction plates and interstate use plates, while they may sound relevant, do not specifically indicate the registration under the IRP framework, which focuses on the apportioned plates for commercial vehicles.
