What is the purpose of an Apportionment ID Card?

The Apportionment ID Card serves a specific purpose related to the registration of commercial vehicles that travel across state lines. It is crucial for trucks weighing over 12,000 lbs that are registered in a state other than the one in which they are currently operating. This card verifies that the vehicle has been registered for apportionment, which means that registration fees are distributed based on the mileage driven in each state, rather than requiring full registration fees in each jurisdiction. This allows for compliance with the International Registration Plan (IRP), which simplifies the process for owners of large trucks that operate in multiple states, making the management of regulatory obligations more straightforward.
