What is an Apportioned (IRP) Registration?
Apportionment is required for vehicles operating in two or more International Registration Plan (IRP) member jurisdictions that have a combined gross weight of more than 26,000 pounds, including the weight of the vehicle and the maximum load, or is a power unit having three or more axles, regardless of weight. Commercial vehicles weighing less than 26,000 pounds operating intrastate in two or more jurisdictions must apportion.
