A prorated tag (also known as an apportioned tag) is a commercial vehicle license plate that has been issued in accordance with the International Registration Plan (IRP). Oklahoma's apportioned license plate has the word "APPORTIONED" displayed on the plate. "Apportioned" means the registration fees for the vehicle are divided up among the states and provinces through which the vehicle travels or within which the vehicle travels. The operator of a commercial motor vehicle bearing an apportioned tag is required to carry a valid cab card inside the vehicle to reflect valid registration. The cab card displays vehicle-specific information, lists each state or province within which the vehicle may operate, and lists the registered weight for each state or province.
