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. RMV has created a one-page poster to help illustrate these commercial testing requirements.
