Fasten your seat belt. You must wear a seat belt when driving.

According to the National Highway Traffic Safety Administration, wearing seat belts can reduce the death rate of passengers over 5 years old by 45% and reduce moderate to severe injuries by 50%. 

In the event of a collision, the seat belt protects passengers from being thrown off the seat or hitting the windshield, helping to avoid fractures, severe head trauma, lacerations, and the possibility of being run over by another car.

Sometimes, you will hear terrible stories about people trapped in the car because of wearing seat belts, but this situation is not common and only accounts for a small part of car accidents. In most car accidents, wearing a seat belt is in your favor.
