IRP registration and apportioned plates

The International Registration Plan (IRP) lets interstate carriers register a vehicle once, in their base jurisdiction, and get an apportioned plate and cab card that cover every member jurisdiction. Registration fees are split by the share of miles driven in each.

Who needs IRP

  • Vehicles that travel in two or more member jurisdictions and have two axles with a gross or registered weight over 26,000 lbs
  • Vehicles with three or more axles, regardless of weight
  • Combinations with a combined weight over 26,000 lbs

How it works

You apply in your base jurisdiction, usually the state where you have an established place of business and keep your records. You report the miles each vehicle traveled in each jurisdiction, and the base state collects the fees and distributes them. Renewals are annual.

Each state runs its own IRP office and online portal, typically through the DMV or department of revenue, so check your base state's IRP site for forms and deadlines.

IRP registration questions

The registration document issued with an apportioned plate. It lists the jurisdictions and weights the vehicle is registered for and must be carried in the vehicle.

Many states issue a temporary authority. Otherwise you need trip permits for each jurisdiction where you are not yet registered.
