IRP overview

The International Registration Plan was developed in the 1960s and 70s to meet the needs of expanding interstate and international commerce.


Commercial vehicles inside Connecticut

As a member state, Connecticut requires all commercial vehicles to apply for the IRP, or to get a special permit, if:

  • Your vehicle travels to another IRP jurisdiction (U.S. states and Canadian provinces); and
  • Your vehicle has a gross weight or combined gross weight in excess of 26,000 pounds or three or more axles combined.

Commercial vehicles from outside Connecticut
Qualified motor vehicles from another IRP jurisdiction need a valid cab card (registration certificate) or a valid trip permit prior to entering Connecticut.

Exempt commercial vehicles
Vehicles that are exempt from IRP include:

  • Government-owned vehicles
  • Vehicles displaying a restricted plate, such as:
