LegalMT
Kei trucks are street-legal and can be titled and registered for on-road use in Montana as of September 2026.
Montana has no kei-specific statute at all. Registration runs through the county treasurer under the ordinary vehicle rules, and in practice kei trucks are registered and driven without a speed or road class attached. The absence of a statute cuts both ways: there is nothing restricting them, and nothing guaranteeing them either, and some sources describe local governments as free to regulate. Confirm with your county treasurer before buying.
