What is the primary function of seat belts in a vehicle?

The primary function of seat belts in a vehicle is to hold passengers in their seats during sudden stops or collisions. When an accident occurs, the force can cause the body to continue moving forward at the same speed as the vehicle. A seat belt restrains this movement, preventing occupants from being ejected from the vehicle or colliding with the interior, which greatly reduces the risk of serious injury or death.

This safety feature is crucial, as it helps keep passengers in a secure position, allowing the vehicle’s safety systems, such as airbags, to work more effectively. Additionally, using seat belts can lead to a significant reduction in fatalities and injuries in traffic accidents, which underscores their vital role in vehicle safety.
