What is the primary purpose of seat belts?

The primary purpose of seat belts is to protect occupants in the event of a crash. Seat belts are designed to restrain occupants, reducing the risk of injury by minimizing movement during a collision. They help absorb and distribute the force of the impact across stronger parts of the body, such as the chest and pelvis, which can significantly reduce the severity of injuries or fatalities.

In vehicles, seat belts also play a critical role in keeping occupants securely positioned within the confines of the vehicle, ensuring that they remain in their seats and do not collide with other passengers or the interior of the car during a crash. This function enhances the overall safety of everyone inside the vehicle.

While comfort, preventing movement, and helping the driver focus may be secondary benefits, they are not the main intention behind the design and use of seat belts. The fundamental aim is to safeguard the people inside the vehicle during unforeseen events such as collisions, underscoring the importance of always wearing a seat belt for safety.
