Washington kei truck registration guide

1. 1

   Clear customs & gather federal documents

   Import a vehicle at least 25 years old and keep your CBP 7501 entry, NHTSA HS-7 (Box 1), EPA Form 3520-1, the original Japanese title/export certificate, and a certified English translation.

2. 2

   Apply for a Washington title at a licensing office

   Take your documents to a vehicle licensing office and complete a Vehicle Title Application. Sign in front of the licensing agent (or a notary). Bring your WA driver license and the import paperwork.

3. 3

   Complete a WSP VIN inspection if requested

   Imported vehicles and non-standard VINs are commonly flagged. The licensing agent issues a Washington State Patrol Inspection Request Form; you then schedule the WSP appointment to verify the chassis number.

4. 4

   Register, pay fees, and get plates & tabs

   Pay title and registration fees (based on weight and your county) and receive Washington plates, a registration certificate, and tabs.

5. 5

   Insure the vehicle and confirm equipment

   Carry Washington liability insurance and make sure the truck has working headlights, tail/brake lights, turn signals, mirrors, and seat belts before driving.

The biggest obstacle in neighboring states is emissions. California requires CARB certification that imported kei engines almost never have. Washington removed that hurdle entirely: after 38 years, the state's vehicle emission check program ended on January 1, 2020, so there is no tailpipe test standing between your kei truck and a set of plates.

That leaves the speed-limit restriction as the main thing to plan around. For farm, ranch, campus, neighborhood, and in-town use that stays on lower-speed roads, a Washington-registered kei truck is a practical, legal option.

Are kei trucks legal on the road in Washington?

Yes, with a major restriction. Washington will title and register an imported kei truck that is at least 25 years old, but current state-law guidance limits these vehicles to roads with a posted speed limit of 35 mph or less. They are not permitted on interstates, freeways, or high-speed arterials.

Does Washington require an emissions test for a kei truck?

No. Washington ended its statewide vehicle emission check program on January 1, 2020, so there is no emissions test to register. (Driving a vehicle with tampered emissions equipment or one that visibly smokes is still illegal.) The absence of an emissions program is a key reason Washington is more workable than California.

Can I drive my kei truck on I-5 or Highway 99?

No. The 35 mph rule is based on the posted limit of the road, not the speed you travel. Interstates like I-5 and arterials posted above 35 mph are off limits even with valid plates. Plan routes on lower-speed local and rural roads.

Will Washington accept a Japanese VIN that isn't 17 characters?

Yes. A licensing agent reviews your federal import documents and, if needed, issues a Washington State Patrol Inspection Request Form so WSP can verify the chassis number against your paperwork before the title is issued.

Do I need a safety inspection?

Washington does not run a routine periodic safety inspection program for passenger vehicles. You may, however, be sent for a WSP VIN inspection during titling, and the vehicle must have functioning required equipment (lights, signals, mirrors, seat belts) to be driven legally.

Is the 35 mph limit ever going to change?

There is ongoing advocacy to expand kei access in several states, but as of 2026 Washington has not adopted a law granting full road use. Treat the 35 mph cap as current and confirm the latest policy with the Department of Licensing before buying.

Washington publishes little kei-specific guidance and policy can change. Confirm current titling, road-use, and equipment rules with the Department of Licensing before purchasing. This page is informational only and not legal advice.
