What Is a Washington Trip Permit?

A Trip Permit grants temporary authorization (3 days / 72 hours) for commercial vehicles to operate in Washington without full registration or fuel tax credentials. It’s required for carriers who:

  • Are not registered under IRP (International Registration Plan), and

  • Have a vehicle with a gross weight of 26,000 pounds or more, or

  • Operate three or more axles, regardless of weight.

This permit covers legal operation within the state for the specified duration and is non-renewable once expired.

When You Need a Trip Permit

You need a Washington Trip Permit if:

  • Your truck is based in another state without IRP reciprocity.

  • You are making temporary hauls into or through Washington.

  • You do not have a Washington IFTA fuel tax license (a separate temporary fuel permit may also be needed).

  • You are operating under lease or non-standard authority for a short-term haul.
