An AFV powered by propane or natural gas may only use the Massachusetts Turnpike at or between Interchange 1 in West Stockbridge and Interchange 14 in Weston if the vehicle has a special fuel transportation permit issued by the Massachusetts Department of Transportation. The AFV must conform to applicable federal and state laws and regulations. An AFV powered by compressed natural gas or propane may only use Massachusetts tunnels if the vehicle conforms to applicable federal regulations and industry standards, displays required markings to identify its alternative fuel system, and is not used to transport fuel.
