An Act relative to federal motor vehicle safety standards compliance

This bill updates Massachusetts vehicle registration rules to align with federal standards for older vehicles. It specifically defines "Kei cars" (small Japanese vehicles under 11 feet long, 4.9 feet wide, 6.6 feet tall, with engines ≤660cc) and requires the Massachusetts Registry of Motor Vehicles (RMV) to register all 25+ year-old vehicles imported under federal rules (49 C.F.R. §591), including Kei cars. The RMV must honor federal safety compliance and develop new policies for Kei car registration and inspection stickers. This directly affects owners of imported Kei cars and ensures Massachusetts follows existing federal import guidelines for vintage vehicles.
