Owners of kei cars and trucks, a class of light, miniature vehicles that are primarily of Japanese origin, can resume registering their autos in Massachusetts, the Registry of Motor Vehicles announced Tuesday.

GBH News reported in August that the RMV had stopped registering kei vehicles for the time being while it investigated “industry standards related to Kei-class mini trucks.”

The registry has wrapped up that “preliminary assessment,” it said Tuesday, while “continuing to review safety implications of Kei Vehicles on the public roadways.”

“At this time, owners of Kei Vehicles will be able to register these vehicles effective September 18, 2024. Kei Vehicles that are already registered may continue their existing registration and renewals, without interruption,” the RMV said.

The agency is forming “plans for conducting a formal study” in the future, it said in its announcement.
