Safe Bet: Seat Belts Improve Your Odds
In the United States, motor vehicle accidents are one of the leading causes of death, especially among children and young adults. The simple act of buckling your seat belt every time you get in a vehicle can save your life. If you have not made seatbelts part of your traveling routine, learn why you should change your behavior.
There are three possible impacts caused by a motor vehicle collision:
- The vehicle strikes another object, such as a tree or car.
- The "human impact" occurs. Unbelted occupants slam into the vehicle's interior—the steering wheel, windshield, roof—or into other occupants.
- The final impact takes place within your body as the internal organs smash against other body parts—the heart hitting the sternum, the brain hitting the skull, the lungs hitting the ribs.
Unbelted occupants can also be ejected from the vehicle. This is one of the most damaging events that can happen during a crash.
Here is what seat belts do for you in a collision:
- Hold you securely, taking advantage of the vehicle's own protective crushing effect as it absorbs energy in the first impact.
- Distribute the force of the human impact across the strong parts of the body. Your body hits the belt rather than the steering wheel, windshield, or other hard parts of the interior.
- Prevent occupants from colliding with each other.
- Help the driver maintain control, decreasing the possibility of an additional collision.
- Prevent occupants from being ejected.
