Information for Motorists: Commercial Vehicles
All commercial vehicles, trailers and converter dollies are subject to the Massachusetts Commercial Motor Vehicle Inspection. The Federal Motor Carrier Safety Administration (FMCSA) approved the Massachusetts Commercial Vehicle Inspection as equivalent to the annual FMCSA or “DOT” inspection. If your commercial vehicle/trailer receives a state safety inspection, you are not required to obtain a separate FMCSA or “DOT” inspection.
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. For more information, please visit http://www.massdot.state.ma.us/rmv/inspect/commercial_regs.pdf.
