Are kei trucks street legal in Montana?

Yes. The Montana MVD Title Manual routes Japanese mini-trucks through its unconventional light vehicle process and states that a vehicle passing the required inspection is registered as a passenger car or truck and issued corresponding plates. There is no posted-speed or road-class restriction attached.

Why do some websites list Montana as restricted?

Two reasons, both outdated or misread. Montana requires you to elect either street-legal or off-highway licensing rather than both, which some summaries report as a restriction. And until October 23, 2024, Japanese mini-trucks had to go through a Break/Bond process; the current Title Manual states that no longer applies when the chain of ownership is intact.

Can I register it as both street-legal and an off-highway vehicle?

No. The Title Manual is explicit that unconventional light vehicles cannot be licensed as both. If you want to use public roads, choose street-legal at registration.

The Inspection Checklist for Unconventional Vehicles. It is a self-certification, signed under Montana's unsworn falsification statute, confirming the vehicle carries the lighting, braking, horn, muffler, mirror, tire, fender, and seat belt equipment required by MCA Title 61, chapter 9. Every box must be checked for the vehicle to be street-legal.

Is there a speed limit or road restriction?

None specific to mini-trucks that we could locate in Montana law or MVD guidance. A mini-truck registered street-legal is plated as a passenger car or truck. Note the MV70A requires a slow-moving vehicle sign on any vehicle that cannot exceed 25 mph, which will not apply to most kei trucks.

Can I use a Montana LLC to register if I live elsewhere?

That is a question for your home state, not Montana. Most states require residents to register vehicles where they are principally garaged, and some actively pursue out-of-state LLC registrations. Montana registering the vehicle does not make it lawful for you to drive it on your own state's roads.

The Title Manual states that as of October 23, 2024, Japanese mini-trucks no longer need the Break/Bond process if the chain of ownership is intact. If your documentation has gaps between the foreign registered owner and you, expect the bonded route instead — confirm with your county treasurer.

Montana kei truck registration guide

Unconventional light vehicle · street-legal or OHV, not both

Yes — Montana titles and registers Japanese mini-trucks for street use. The Montana Motor Vehicle Division's Title Manual names Japanese mini-trucks explicitly, routes them through its 'unconventional light vehicle' process, and states that a vehicle that passes the required equipment inspection is registered as a passenger car or truck and issued the corresponding plates. There is no posted-speed or road-class cap attached to that registration.

Bottom line for Montana

Montana is one of the clearest 'yes' states in the country, and the agency source says so in plain language.

The MVD Title Manual (March 2026) lists Japanese mini-trucks and mini-vans as examples of unconventional light vehicles and provides a titling path for them.
You must choose: a vehicle cannot be licensed as both street-legal and an off-highway vehicle. Pick street-legal if you intend to drive on public roads.
Street-legal status requires a fully completed self-certified Inspection Checklist for Unconventional Vehicles (form MV70A), certifying the equipment required by MCA Title 61, chapter 9.
A vehicle that passes is registered as a passenger car or truck with corresponding plates and fees — not as a restricted or low-speed class.
As of October 23, 2024, the manual states Japanese mini-trucks no longer need the Break/Bond process if the chain of ownership is intact.

Resolving the confusion

Why you see Montana listed two different ways

Montana appears in some published state roundups as fully permitted and in others as restricted, sometimes in the same table. Two things explain the split, and neither survives contact with the state's own documents.

First, Montana requires an either/or election: a vehicle can be licensed as street-legal or as an off-highway vehicle, but not both. Summaries that read the OHV branch as the default arrive at 'restricted.' Second, until October 23, 2024, Japanese mini-trucks were routed through a Break/Bond process, which was procedurally heavy enough to look like a restriction. The current MVD Title Manual states that requirement no longer applies when the chain of ownership is intact.

The controlling agency document is unambiguous: complete the MV70A equipment certification, and the vehicle 'will be registered as a passenger car or truck and issued corresponding plates/fees.' Montana imposes no posted-speed limit, no road-class cap, and no local approval requirement on that registration. We are treating Montana as permitted on that basis.

Registration

Titling & registration steps

1
Clear federal import
Import a vehicle at least 25 years old and retain CBP Form 7501, DOT Form HS-7, EPA Form 3520-1, and the Japanese export certificate. The Title Manual notes that if 'export only' is marked on the HS-7, the vehicle cannot be titled or registered.
2
Assemble the ownership chain
Montana's October 2024 change removes the Break/Bond requirement only if the chain of ownership is intact. Keep the export certificate with a certified English translation and every bill of sale or invoice linking the foreign registered owner to you.
3
Complete a VIN inspection
Montana uses a Vehicle Identification Number Inspection (form MV20) performed by an authorized inspector to verify the VIN on a vehicle without a Montana title.
4
Decide: street-legal or OHV
A vehicle cannot hold both licenses. If you want to drive on public roads, choose street-legal — you cannot add it later without redoing the registration.
5
Self-certify equipment on form MV70A
Complete the Inspection Checklist for Unconventional Vehicles in its entirety. It covers head lamps, tail lamps, reflectors, stop lamps, brakes on all wheels, horn, mufflers, at least one mirror, tires, fenders or splash flaps, and seat belts, all as required by MCA Title 61, chapter 9. It is signed under penalty of law.
6
Apply through your county treasurer
Submit the Application for Certificate of Title for a Motor Vehicle (form MV1) with supporting documents. On approval the vehicle is registered as a passenger car or truck with corresponding plates and fees.

The MV70A is a self-certification, not a station inspection — you are attesting to the equipment yourself, under an unsworn-falsification statute.

Equipment

What the MV70A checklist requires

Every box must be checked before the vehicle is considered street-legal:

•Two head lamps, mounted 24–54 inches from the ground, high beam projecting roughly 350 feet and low beam roughly 100 feet.
•At least one red tail lamp visible 500 feet to the rear, mounted 15–72 inches from the ground, plus a white lamp illuminating the rear plate.
•Two red rear reflectors, mounted 15–60 inches from the ground.
•Stop lamps incorporated into the tail lamp, if the vehicle is so equipped.
•Brakes on all wheels in good working condition.
•An electric horn audible at 200 feet, controlled by the driver, and not unreasonably loud or a whistle.
•A muffler system with no cut-outs or bypasses.
•At least one mirror giving a view 200 feet to the rear.
•Pneumatic or solid rubber tires — no metal tires.
•A slow-moving vehicle sign if the vehicle cannot exceed 25 mph.
•Fenders, splash aprons, or flaps on the rearmost wheels.
•Seat belts complying with MCA Title 61, chapter 9.

Practical notes

Residency and the LLC question

Montana is heavily marketed as a registration workaround because it charges no sales tax on vehicles and offers permanent registration for older vehicles. That marketing usually involves forming a Montana LLC to hold a vehicle owned and driven by a resident of another state.

That is a separate legal question from whether Montana will register a kei truck, and it is one your home state — not Montana — decides. Most states require a resident to register a vehicle in the state where it is principally garaged, and several have pursued owners over out-of-state LLC registrations. If you live in Montana, the pathway on this page is straightforward. If you do not, do not treat Montana registration as a way around your own state's rules.

If your documentation has gaps between the foreign registered owner and you, expect the bonded route instead — confirm with your county treasurer.

Montana's kei truck pathway comes from the MVD Title Manual, an agency procedure document that is revised periodically rather than a statute, so it can change without legislation. Individual county treasurers may also apply the unconventional light vehicle process inconsistently. Confirm current requirements with the Montana Motor Vehicle Division before purchasing.
