The National Highway Traffic Safety Administration (NHTSA) finalized a rule this month requiring all new passenger vehicles to include visual and audible seatbelt warning systems for rear seats and enhanced warnings for front seat occupants. This mandate aims to address seatbelt usage among rear-seat passengers, who have historically shown lower compliance rates compared to front-seat occupants. The rule is set to take effect for front seat warnings on September 1, 2026, and for rear seat warnings on September 1, 2027.
