IRP Apportioned Plates (48 States)

How it Works

If you use your commercial vehicle in two or more states, you can save money on registration fees with IRP. When you register a commercial vehicle in IRP, you pay pro-rated (apportioned) fees based on the percentage of highway mileage traveled in each jurisdiction.

For example, if an interstate vehicle operates 50 percent of its total mileage in California and 50 percent of its total mileage in Nevada, that vehicle is assessed 50 percent of the registration fees in each state (rather than paying the full amount in each state). The fees for all of the jurisdictions where the vehicle operates are processed through IRP Clearinghouse by your base jurisdiction.

What Vehicles Qualify?

You can register any vehicle that meets the California Vehicle Code (CVC) definition of “commercial vehicle” and travels in California and at least one other state.

Most California based commercial vehicles operating at a gross vehicle weight (GVW) or combined gross weight (CGW) of 26,001 pounds or more must have either IRP registration or alternative commercial trip permits from the appropriate foreign jurisdictions when operating outside California. Vehicles weighing 26,000 pounds or less and operating strictly interstate may be exempt from IRP or temporary commercial trip permits under reciprocal agreements.

Regardless of your vehicle’s operating weight and operational plans, you should always contact the foreign jurisdiction you are traveling to if you choose not to file for IRP.
