What is the role of seat belts during a vehicle collision?

[DelMargaret]

During a vehicle collision, the role of seat belts is to reduce the likelihood of death or serious injury in traffic accidents by minimizing the secondary impact forces that pose internal collision risks. They ensure proper occupant positioning to maximize the effectiveness of airbags and prevent occupants from being ejected from the vehicle or experiencing rollover. Seat belts are a vehicle safety device designed to protect occupants from harmful movements caused by collisions or sudden stops. The correct way to use a seat belt is: 1. First, adjust the height of the seat belt. If it is too high, it may tighten around the neck during an emergency, and if it is too low, it may not fully restrain the body from moving forward. 2. After fastening the seat belt, it should not be too loose or too tight—approximately leaving space for two fingers ensures safety without causing discomfort.
