Arizona kei truck street-legal guide
Titling, registration, emissions & on-road checklist
Arizona allows qualifying Japanese kei trucks on public roads when they meet state safety rules and are registered correctly.
Bottom line for Arizona
Vehicles at least 25 years old may be exempt from federal FMVSS and EPA certification. At the state level, a street-legal kei truck typically needs:
- Compliance with ARS Title 28, Article 16 safety equipment
- An OHV/ATV or qualifying pickup title
- A current $25 OHV decal and registration sticker
- Valid Arizona liability insurance
Background
What is a kei truck?
A kei truck (軽トラ, keitora) is a Japanese mini utility pickup built under kei-class limits — roughly under 3.4 m in length and 660 cc displacement. Most imports we handle are 25+ years old, which shifts the main compliance focus from federal certification to Arizona titling, registration, and equipment rules.
Arizona currently titles kei trucks as Off-Highway Vehicles (OHVs) even when owners plan to drive primarily on pavement. Selecting Primary On-Road Use at registration makes the truck eligible for ordinary street and highway use, including freeways, when weight and equipment requirements are met.
Registration
Titling & OHV registration steps
- 1
Title the vehicle in Arizona
Bring your import paperwork (CBP 7501, EPA 3520-1), a translated title, and complete a Level I VIN inspection at an MVD or authorized third-party office.
- 2
Declare primary on-road use
On the OHV Vehicle Use Form, select Primary Use — On Road. That documents your intent to drive on public streets and highways, not off-road trails only.
- 3
Purchase the annual OHV decal
A $25 OHV decal is required each year for off-highway vehicles under 2,500 lbs, including kei trucks registered for on-road use.
- 4
Equip the truck for highway use
Your vehicle must meet Arizona safety requirements under ARS Title 28, Chapter 3, Article 16 before registration is approved.
- 5
Carry valid insurance
Minimum liability coverage: $25,000 per person, $50,000 per accident, and $15,000 property damage.
- 6
Complete the OHV safety course
Since January 1, 2025, Arizona requires a free online OHV safety course once per owner to renew your decal. It takes about 20 minutes and can be done in office or through your Arizona MVD Now account.

FAQ
Common questions
- Do kei trucks need emissions testing in Phoenix?
- Generally not when titled as OHVs with ATV on the title, or when registered as a classic vehicle with approved classic-car insurance. If your truck is titled as a regular truck, you may need to reclassify to ATV at MVD or obtain classic car insurance to avoid emissions requirements in applicable counties.
- Is there a speed limit for OHV-plated kei trucks?
- No statewide speed cap applies when you register for Primary On-Road Use. Freeway driving is allowed. The 55 mph limit people mention applies to off-road-primary OHVs, not on-road registrations.
- Can I insure a kei truck in Arizona?
- Yes. Many carriers — including State Farm, Progressive, and American Modern — offer liability policies. For classic registration routes, Grundy and American Collectors Insurance tend to be reliable for kei-class vehicles.
- Can I use freeways like I-10, I-17, or Loop 202?
- Yes, with Primary On-Road Use selected, valid insurance, required safety equipment, and an OHV title. There is no freeway restriction for that registration type.
- Will ADOT accept a short Japanese VIN?
- Yes. Arizona MVD titles vehicles with fewer than 17 digits after a Level I VIN inspection and manual entry.
- Are kei vans, dump beds, or specialty bodies treated differently?
- No. Pickups, vans, flatbeds, dumps, and other kei-class utility bodies follow the same titling and compliance path, provided weight and equipment requirements are met.
- My title says truck instead of ATV — what now?
- Request an OHV/ATV reclassification at MVD to simplify registration and avoid emissions hurdles, or keep the truck title and use classic car insurance where emissions would otherwise apply.
Emissions requirements vary by Arizona county. Rules change — confirm current ADOT/MVD guidance before registering. This page is informational only and not legal advice.
