An Act to create an open-container law for marijuana

This bill creates a new open-container law specifically for marijuana products in Massachusetts. It prohibits possessing an "opened container of marijuana" (like edibles with broken packaging or altered state) in the passenger area of any vehicle on public roads or accessible areas, with a $100-$500 civil penalty for violations. The law explicitly defines "opened container" to include unsealed edibles and products not from licensed facilities. It exempts commercial passenger vehicles with separated driver/passenger areas and the living quarters of house coaches or trailers. The bill amends Chapter 94G to remove an existing subsection (d) related to this regulation.
