Can I own one here
Owning one in Yellowstone County.
On your own land, yes
Owning a kei truck and working it on a ranch, a farm, a mine or private property does not depend on a road title. Some states still ask for a title or an off road registration.
A 25 year truck on the road
Open to road use. Montana's Motor Vehicle Division titles and registers Japanese mini-trucks as unconventional light vehicles. Once the owner certifies its street equipment, a kei truck registers as a passenger car or truck with ordinary plates.
A newer governed truck
Off highway vehicle. Titled and registered as an OHV through the county treasurer. The title manual lets a mini-truck owner choose OHV instead of street-legal.
Roads and towns

County roads To confirm
The clerk's page of county ordinances lists seven, on parkland, medical marijuana, community decay, dogs, rabies vaccination and raffles, and none concerns off-highway vehicles. The 2025 road policies resolution, 25-67, was seen only in a search summary. The commissioners' resolutions were not searched. Under MCA 23-2-824(2) the board of county commissioners may give permission for an off-highway vehicle on a county road inside a municipality, and that permission need not be an ordinance. Part of the county lies within the Crow Indian Reservation, where tribal and federal road authority applies on tribal and BIA roads, and a tribal rule on off-highway vehicles was not looked for. ordinance list read, no off-highway vehicle ordinance in it; no resolution read, read 28 October 2026

The ground
Yellowstone County, counted.

Importing a kei truck
The essentials, in short.
A truck under 25 can come in only as governed off road equipment, and only if its engine family held an EPA nonroad certificate for that model year. No kei engine family was certified for mini trucks before model year 2010, so a truck built after 31 October 2001 and before model year 2010 has no federal door until its 25th birthday.
Two lanes
A road truck must be 25 years old by its own build date. A newer truck comes in only as governed off road equipment with a certified engine.
The 25 percent duty
Every kei truck pays the 25 percent truck duty at the port, whatever its age.
The paperwork
The customs entry and the two federal declarations, DOT Form HS-7 and EPA Form 3520-1, travel with the truck to your title office.
The title
Keep every stamped paper with the truck. Your state title office asks to see them.
