Motor Vehicles - Required Equipment - Rear Occupant Alert Systems (Hot Cars Act)

HB 777, the "Hot Cars Act," requires new motor vehicles with rear seating (like passenger cars, trucks, and multipurpose vehicles) sold in Maryland after October 1, 2029, to include a rear occupant alert system. This system must alert drivers to check the back seat after turning off the engine, meeting federal standards set by the National Highway Traffic Safety Administration (NHTSA). The law prohibits dealers from selling non-compliant vehicles and bars the Motor Vehicle Administration from registering such vehicles. It directly affects car manufacturers, dealers, and vehicle buyers in Maryland, with compliance tied to upcoming federal safety rules.
