Apportioned Plate

Definition

An apportioned plate is the registration tag issued under the International Registration Plan (IRP) that lets a single commercial vehicle operate legally in multiple US states and Canadian provinces with one license plate. The carrier registers in their base jurisdiction; the base jurisdiction collects fees and redistributes them to the other member jurisdictions in proportion to the miles traveled in each. Required for any qualified motor vehicle that crosses jurisdiction lines for hire - typically vehicles over 26,000 lbs gross weight or three-or-more-axle vehicles. Renewed annually; mileage data filed each year drives the next year's apportionment percentages.
