Every commercial motor vehicle must be licensed, or registered, according to the laws of the jurisdictions in which it operates. Vehicle licensing fees and procedures vary from state to state and can depend upon:
The type of vehicle,
The weight of the vehicle,
Where travel will take place,
The kind of motor carriage being conducted, or
The value or age of the vehicle.
When a vehicle will operate primarily within a single state, a base plate is obtained from that state, depending on the weight and type of vehicle, the registration may authorize travel within the base state only.
All “qualified” vehicles that cross state lines and exceed 26,000 pounds in gross vehicle weight, gross combined weight, or registered gross vehicle weight, and power units with three or more axles must either participate in the International Registration Plan (IRP) or purchase trip permits.
Some states require in state registration or a trip permit at under 26,000 pounds, so vehicles that travel in those states may obtain apportioned plates and participate in IRP as well.
When obtaining vehicles through a merger or acquisition, you can obtain temporary IRP credentials if you already have an existing IRP account with your base state. Otherwise, trip permits will be required.
