You are correct with regard to Maine only registering vehicles that were manufactured to meet federal regulations for safety and emissions. The exception is for antique vehicles (which were manufactured to the regulations of their time and can only be driven in limited circumstances) and golf carts which are allowed on some coastal island roads. And it does mean that vehicles which don’t meet these standards aren’t supposed to be registered. When we find that any such vehicle has been inappropriately registered, we revoke that registration, which is what recently happened to a handful of pre-1995 Mitsubishi Delica vans. This is all, of course, to ensure safety on Maine roads and protect the environment.
