  • Has three or more axles regardless of weight, or

You do not need a fuel permit or license to operate a diesel-powered vehicle driven solely in California. Likewise, you do not need a fuel permit or license for a diesel-powered recreational vehicle, such as a motor home or a pickup truck with a camper, if the vehicle is not used in connection with a business operation.

Do I need an IFTA license?

You qualify for an IFTA license if you operate your qualified motor vehicle in California and any other U.S. state or Canadian province that is a member of the International Fuel Tax Agreement. You should register for IFTA with California as your base jurisdiction if all of the following apply:

  • Your qualified motor vehicles are based in California for vehicle registration with the California Department of Motor Vehicles (DMV);
  • You perform operations from an established physical place of business in California (a post office box, mail drop address, or agent address boxes not qualify);
  • Your fleet's qualified motor vehicles travel on California highways; and
  • You maintain the operational control and operational records for your qualified motor vehicles in California or you can make those records available in the state.

Do I need a DI license?

You qualify for a DI license if you operate at least one qualified motor vehicle powered by diesel fuel, and

  • You travel only in California and Mexico; or
  • You travel in California and your business is based outside California in a jurisdiction that is not a member of the International Fuel Tax Agreement. Currently, the nonmember jurisdictions are Mexico; Alaska, Hawaii, and the District of Columbia (DC); and Canada's Nunavut, Yukon Territory, and Northwest Territories.

Is there an alternative to an IFTA or DI registration?

California Fuel Trip Permits are used for occasional trips into California. They also allow out-of-state registered vehicles to enter and travel in California for four consecutive days.

  • If you qualify for an IFTA license but do not choose to register, you must obtain fuel trip permits to travel into or through each IFTA member state. When you return to California, you must purchase a BOE-123, California Fuel Trip Permit before you reenter the state. In addition, carriers traveling in non-IFTA jurisdictions must continue to comply with the fuel tax reporting requirements of those jurisdictions.
  • If you qualify for a DI license but do not choose to register, you must obtain a BOE-123, California Fuel Trip Permit before reentering California from Mexico.
