Do rear passengers in sedans need to fasten seat belts on highways?

[DiDelilah]

Rear passengers in sedans need to fasten seat belts when driving on highways. More relevant information is as follows: 1. Seat belt usage while driving: According to the National Road Traffic Safety Law, drivers and passengers in motor vehicles must use seat belts as required. During vehicle operation, both drivers and passengers not wearing seat belts are considered illegal acts. 2. Consequences of not wearing seat belts: Sitting in the rear seat without fastening the seat belt not only seriously threatens the safety of front-row occupants but also poses safety risks to the passengers themselves. This is because during vehicle deceleration, passengers inside the car are accelerating relative to the vehicle. In this scenario, front passengers hitting the windshield experience lower acceleration than rear passengers, making rear passengers more likely to suffer severe injuries.
