Apportioned Vehicle Registration
Nevada is a member of the International Registration Plan, which is a cooperative agreement for registering vehicles that travel into two or more jurisdictions (states or Canadian provinces). Each state receives a portion of a vehicle's registration fees based on the percentage of miles traveled in that state.
The home or "base" jurisdiction is responsible for registering the vehicle and collecting and disbursing various fees such as basic registration, Nevada's governmental services taxes, highway use taxes, weight taxes, etc. The advantage for the industry is that a given vehicle has to be registered only once. Apportioned registrations are issued only on the "power unit"; trailers are issued normal registrations.
Trucks registered under IRP receive an "Apportioned" license plate and a "cab card". The cab card is similar to a passenger vehicle registration slip. It identifies the vehicle, home state and license plate number, the registered maximum gross weight by jurisdiction, and all the jurisdictions in which the vehicle is properly registered. Applications are available in Motor Carrier Forms.
Truckers who do not register under IRP can either get a single-trip permit to enter another state or they can "dual register" their vehicles in other states and display two or more license plates.
