What are the functions of car seat belts

1. Protect the safety of the driver and passengers: When a vehicle collision occurs, seat belts effectively restrict movement of the body inside the vehicle, reducing the impact force on the body.

2. Reduce fatality rates: Studies show that proper use of seat belts can reduce the fatality rate for drivers and passengers by approximately 50%.

3. Reduce injuries: Even if seat belts cannot completely prevent injury, they can limit the extent of injury, such as limiting the impact force on the head and chest.

4. Improve safety: In addition to drivers and passengers, the use of child seats and infant carriers is also part of the seat belt system, which can improve the safety of children when traveling in a car.
