This assumes of course, that your body is not ejected from the car. Seat belts are designed to absorb the impact of the collision and transfer that impact from your body. I'm a good driver. Even if you have a perfect driving record and have never been involved in a traffic collision, it is not a sound reason to avoid wearing your seat belt. Being a good driver can be a determining factor in your ability to avoid accidents, but there are many other drivers on the road who are not as careful.

An air bag increases the effectiveness of a seat belt by up to 40 percent. There are many ways to make your seat belt more comfortable.
