In a move aimed at enhancing road safety, a new federal rule will require passenger vehicles to install alarms that alert drivers if rear seat passengers have not fastened their seat belts. This regulation, set to take effect by 2027, aims to reduce injuries and fatalities associated with unbuckled passengers. The federal agency overseeing this initiative has finalized the requirements, emphasizing the importance of reminding all occupants to buckle up for their safety. As part of this initiative, warnings will be introduced to ensure that backseat occupants are also protected in case of an accident.
