U.S. Authorities Propose Rear Car Seat Belt Enforcement

Every year in the U.S., thousands of incidents result in rear car seat passenger fatalities due to traffic collisions caused by the absence of seat belt usage. The U.S. National Highway Traffic Safety Administration (NHTSA) aims to change this narrative, proposing alterations for passenger cars, trucks, and some bus models, requiring all rear seat passengers to buckle up.

Currently in the U.S., only 48 out of 50 states have laws mandating drivers and front seat passengers to wear seat belts. Additionally, 10 states do not require rear seat passengers to buckle up while the vehicle is in motion. According to NHTSA, the seat belt usage rate for front seat occupants in the U.S. is approximately 90%, while for rear seat passengers it is around 78%.

The proposed new regulations apply to vehicles weighing less than 4,536 kg (10,000 lbs). Part of this new provision requires car manufacturers to implement a rear seat belt reminder system, providing both audio and visual alerts at 60-second and 30-second intervals respectively, if the seat belt remains unfastened while the vehicle is in motion.

To circumvent the law, the NHTSA proposes a system capable of identifying children, teenagers, or adults sitting in the rear seats, and must recognize removable child seats. Specifically for child seats, as they already come with their own safety harnesses, additional seat belt usage within the vehicle is unnecessary. The standard set forth requires the identification system to detect an individual weighing at least 21kg and measuring at least 114cm, the typical size of a 6-year-old child, the average age when families transition away from child seats.
