Massachusetts registered single, full, or semi-trailers used in commerce, that have a gross vehicle weight rating (GVWR) over 3,000 pounds or commercial vehicle/trailer combinations with a gross combined weight rating (GCVWR) of over 10,000 pounds are subject to this requirement, as are all heavy duty motor vehicles (over 10,000 pounds GVWR) and converter dollies. Trailers and converter dollies in use after January 1, 2009 must be in compliance with this new inspection.
Commercial vehicles, trailers and converter dollies are subject to the Massachusetts Commercial Motor Vehicle Inspection. This inspection is the equivalent to the annual Federal Motor Carrier Safety Administration (FMCSA) inspection (known as a “DOT inspection”). When your vehicle/trailer receives a state safety inspection beginning October 1, 2008, you will not be required to obtain a separate annual “DOT” inspection.
