1. When a Fuel Permit Is Required Without IFTA

A Washington State fuel permit is required if:

  • You are operating a commercial motor vehicle in Washington and do not have IFTA credentials, and

  • Your vehicle has a gross vehicle weight of 26,001 lbs or more, or

  • You operate in intrastate commerce only (within Washington) and are not registered under IFTA.

Example: A small fleet of trucks operating solely within Washington that hasn’t registered for IFTA will need a special fuel permit to legally buy and use diesel or gasoline.


2. Types of Fuel Permits in Washington Without IFTA

  1. Temporary Fuel Permits – good for a single trip or limited duration.

  2. Annual Fuel Permits – for long-term intrastate operations without IFTA registration.

Both types allow the carrier to purchase fuel legally in Washington without IFTA reporting.
