What is the purpose of safety belts?

Safety belts are designed primarily to prevent injury in the event of a collision. When a vehicle experiences a sudden stop or impact, safety belts restrain occupants and help keep them securely in their seats. This function significantly reduces the risk of serious injuries or fatalities by preventing ejection from the vehicle and minimizing movement within the cabin during a crash. In essence, safety belts are critical for enhancing passenger safety by absorbing some of the forces involved in an accident and distributing them across stronger parts of the body, thereby reducing the likelihood of harm.

Comfort, staying awake, and steering control do not relate directly to the primary function of safety belts. While comfort may be a secondary benefit for some passengers, it is not the reason for their existence. Safety belts do not influence alertness or prevent fatigue, nor do they serve any function related to vehicle steering control. Their sole purpose is focused on protecting individuals during a vehicular accident, making their role essential for road safety.
