Kei Trucks in California

Very hard to register: the emissions rule, and what owners do instead

Kei trucks in California are the hardest in the US to register. The 25-year import rule doesn't help here, because the DMV also needs California emissions approval.

Very hard in CaliforniaRoad registration needs CARB emissions work and testing. The DMV says that may be expensive or impossible.

The law

What the rules say about kei trucks here

There's no kei-truck law here. The barrier is the DMV's rule for imported vehicles.

The key line (California DMV, imported vehicles) cannot be registered in California, unless the vehicle is modified and tested under CARB's direct import program
  • The federal 25-year exemption doesn't change California's emissions rules.
  • The DMV says imported off-highway vehicles can't be converted to California emissions rules either, so a green (off-road) sticker is unlikely.
  • Titles for vehicles without US labels are branded "NON-USA".
CARB is the California Air Resources Board. For an import built in 1975 or later, a CARB-licensed lab has to modify and test it before CARB issues a certificate. Only vehicles from 1967 and older skip this.

Options

What Californians do instead

Three real options for kei trucks in California. None is a quick road-legal fix.

  1. 1
    Use it on private landFarms, ranches, vineyards and big properties. Owners use kei trucks off the public road without plates.
  2. 2
    Try the CARB routeHire a CARB-licensed lab to modify and test it; CARB then issues the certificate the DMV needs. For trucks built after 1995, the DMV also asks for proof the truck meets US safety standards. The DMV warns it may be expensive or impossible; one owner puts it near $10,000 on top of the truck.
  3. 3
    Watch for a law changeWe found no California kei truck bill in 2025 or 2026. Other states changed their rules after owners pushed.

Before you buy one in California

  • "Street legal" in an ad usually means legal in another state. A title from Arizona, Texas or anywhere else won't get you California plates.
  • If a seller says the truck is registered here, ask to see its current California registration card in the seller's name.
  • The California DMV's own page: Register an imported vehicle ↗.
  • Questions about the CARB route: CARB's phone line, (800) 242-4450, or its questions page ↗.

Roads

Can you drive one on California roads?

Not without California registration.

The DMV says fees for a vehicle brought into California are due within 20 days, and it won't register an import that hasn't passed CARB testing.

Questions

California questions

Are kei trucks legal in California?

You can own one, but registering it for the road is very hard. The DMV needs CARB emissions modification and testing, which it says may be expensive or impossible.

Can I register a 25-year-old kei truck in California?

The 25-year rule is federal. California still needs its own emissions approval, so age alone doesn't get you plates.

Can I get a green sticker for a kei truck?

Very unlikely. The DMV says imported off-highway vehicles can't be converted to California emissions rules unless they were built to them, and kei trucks weren't.

Are older kei trucks exempt in California?

Only vehicles from 1967 and older skip CARB testing, and kei trucks that old are rare. A truck built in 1975 or later needs the lab test.

Can I register it in another state and drive it in California?

Not as a California resident. The DMV says fees for a vehicle brought into California are due within 20 days, and an import still needs CARB approval before it gets California plates.

I saw a kei truck driving in California. How?

It may be one of the few that passed CARB testing, a visitor's truck with out-of-state plates, or one driven without valid registration, which California Vehicle Code 4000 doesn't allow.

What does a NON-USA title mean?

California brands the title "NON-USA" on vehicles that lack the US safety and emissions labels.

Can I use a kei truck on my farm?

Yes. Most kei trucks in California work on farms, ranches, vineyards and other private land, off public roads.
