According to the American Automobile Association, since 1964 all cars sold in the United States have
been equipped with seat belts. (These are also called safety belts.) Mary studies of automobile accidents
have shown that safety belts can save lives. One study showed that forty percent of those killed in auto
accidents could have been saved if they had been wearing seat belts.
Unfortunately belts are worn only by a small percentage of drivers and passengers-about fifteen percent
in cities, and only nine percent in small towns. And safety belts cannot protect people who do not wear them.
In order to find out what kinds of people do wear seat belts a study was made in several cities of the
United States. The following facts were learned about those who use their safety belts:
1. They do not smoke while driving.
2. They have had more education than non-users.
3. They know someone who was injured(but not killed)in an automobile accident.
Advertisements based on these facts have been printed in newspapers and magazines in order to teach
people the importance of using seat belts. But these advertisements have not helped much. Some people
believe there should be a law requiring drivers and passengers to use safety belts. In Australia, where there
is such a law, deaths in auto accidents have decreased twenty-four percent.
