Why do you need to wear a seat belt?

The cabin of your car or truck is designed to absorb impact and keep the occupant area fairly stable. By wearing a seat belt you will be held in place in the cabin and greatly improve your chance of survival. If you are in an accident not wearing a seat belt you will be thrown around inside the car sustaining many more serious "crashes" inside the vehicle or, you could be thrown out of the vehicle into oncoming traffic or even be squashed by your own car. You might ask yourself this question. Would you ever go flying in a high powered military jet and not buckle up? Of course not. And yet, there is nothing going on inside that jet that is any more violent than a car crash.
