Are Kei Trucks Legal in Arizona?

Arizona has not banned kei trucks and has no kei-specific rule of any kind. What it has is a single sentence in its foreign-vehicle statute that everything turns on. Section 28-2052(D) requires the owner of a vehicle imported into the country to obtain, before a title issues, "a certificate of compliance that states that the vehicle meets all federal vehicle equipment and emissions equipment requirements." The two carve-outs the statute does provide are for pre-1998 golf carts and neighborhood electric vehicles — there is no carve-out for age, and none for the federal 25-year rule.

The practical question is therefore whether the federal import paperwork for a 25-year-old vehicle satisfies that requirement. For a kei truck the federal position is exemption, not compliance: NHTSA form HS-7 box 1 claims the 25-year exemption under 49 U.S.C. § 30112(b)(9), and EPA form 3520-1 code E claims the 21-year exemption. In practice owners present that package as the certificate of compliance. We want to be straight with you: the statute says "meets all federal ... requirements", not "is exempt from them", and we could not find any ADOT page, rule or memorandum stating that the 25-year exemption satisfies § 28-2052(D). That is the live ambiguity in Arizona, and it is the reason this page says conditional rather than permitted.

There is a second, procedural gate. Section 28-2052(C) allows the department to inspect a foreign vehicle before issuing a title or registration, including an examination to establish compliance with § 28-955 under standards set by the director of environmental quality. ADOT's own Motor Vehicle Manual guidance for dealer title clerks lists among the circumstances when a Level I, II or III inspection is required: "A title and/or title and registration is requested for a ‘foreign’ vehicle (Grey Market)". So expect an inspection as a matter of course, not as an exception.

Two further things we checked so you do not have to. A kei truck is not an off-highway vehicle under A.R.S. § 28-1171, because that definition is limited to vehicles designed, modified or purpose-built primarily for recreational nonhighway all-terrain travel — so the OHV classification is not a trap waiting for you, but neither is it an alternative route. And we could not resolve emissions testing in the Phoenix and Tucson areas: the Arizona Department of Environmental Quality exemptions page is behind a bot wall and we could not retrieve it, so if you live in either area treat vehicle emissions testing as an open question to put to ADEQ directly. We found no Arizona bill, rule change or MVD bulletin between 2021 and 2026 addressing kei vehicles.

What you can do in Arizona

Private property, farm, ranch and off-road use is unaffected and needs no Arizona registration.

If you want to register for road use, the sequence that matters is: get the complete federal import package first — the stamped HS-7 showing the 25-year exemption, the EPA 3520-1, and the CBP entry paperwork — then ask an MVD office or an authorised third-party provider, before you buy, whether they will accept that package as the certificate of compliance required by A.R.S. § 28-2052(D). Get the answer in writing if you can, because this is the one question on which Arizona outcomes genuinely appear to vary.

If you live in Maricopa or Pima county, put a second question to the Arizona Department of Environmental Quality about whether the vehicle is subject to emissions testing and, if so, how a Japanese-market engine is tested. We could not establish this and it is better resolved before a bank transfer than after one.

How this fits the national picture

Importing a vehicle twenty-five years or older is a federal matter and is settled. Registering one for the road is decided state by state, which is why the answer changes when you cross a line on a map. Our state-by-state guide covers all fifty, including why states disagree and the AAMVA guidance most restrictions trace back to.

We are based in Goshen, New York, and New York is one of the states that will not register these for road use. We say so on our own state's page because it is true, not because it helps us. We will not tell you a kei truck is street legal in the USA.

Common questions

Are kei trucks legal in Arizona?

Arizona has no rule that mentions kei vehicles. Arizona Revised Statutes section 28-2052(D) requires that before the department issues a certificate of title to a vehicle imported into this country, the owner must obtain a certificate of compliance stating that the vehicle meets all federal vehicle equipment and emissions equipment requirements. Whether the federal 25-year exemption paperwork satisfies that requirement is not addressed in any Arizona document we could find.

Does Arizona inspect imported vehicles?

Yes. Arizona Revised Statutes section 28-2052(C) allows the department to inspect a foreign vehicle before issuing a certificate of title or before registration. The Arizona Department of Transportation Motor Vehicle Manual lists a request for title or title and registration for a foreign or grey market vehicle among the circumstances in which an inspection is required.

Is a kei truck an off-highway vehicle in Arizona?

No. The definition of off-highway vehicle in Arizona Revised Statutes section 28-1171 is limited to vehicles designed, modified or purpose-built primarily for recreational nonhighway all-terrain travel, which does not describe a kei truck built for road use in Japan.

Has Arizona banned kei trucks?

No. As of 4 October 2026 we found no Arizona statute, administrative rule, Motor Vehicle Division bulletin or legislation from 2021 onwards that addresses kei vehicles specifically. Arizona applies its general foreign-vehicle titling requirement in Arizona Revised Statutes section 28-2052.

What is the certificate of compliance Arizona asks for?

Arizona Revised Statutes section 28-2052(D) requires the owner of a vehicle imported into the country to obtain, before a certificate of title is issued, a certificate of compliance stating that the vehicle meets all federal vehicle equipment and emissions equipment requirements. The statute exempts only golf carts and neighborhood electric vehicles manufactured or modified before 17 June 1998.

This page describes what we could establish from the source above on the date shown. It is not legal advice, and kei registration rules have moved in both directions every year since 2021 — confirm with the Arizona registering authority before you buy. Payment for an imported vehicle is by bank transfer and is not reversible.
