Alternative Fuel Vehicle (AFV) Access to Massachusetts Turnpike and Tunnels

No vehicle, regardless of how it is propelled, may transport hydrogen, propane, or natural gas on the Massachusetts Turnpike at or between Interchange 1 in West Stockbridge and Interchange 14 in Weston unless the vehicle has a special fuel transportation permit issued by the Massachusetts Department of Transportation.

Vehicles propelled by hydrogen, propane, or natural gas are banned from using Turnpike or Metropolitan High way System tunnels, with limited exceptions for the Ted Williams Tunnel and the Central Artery North Area Tunnel. Vehicles powered by CNG, propane, or private passenger vehicles powered by hydrogen may use these tunnels if exhaust fans are operating, fuel capacity complies with national standards, other safety conditions are met, and they are not transporting CNG or propane. Additionally, private passenger vehicles powered by hydrogen may use these tunnels if they meet state registration requirements, comply with all applicable federal laws and regulations, and are not transporting gaseous hydrogen.
