Many countries have passed safety laws that require seat belts in vehicles. A modern three-point seat belt, also called a safety belt, is a harness to prevent the driver or a passenger from flying forward and hitting hard against the interior of a vehicle during a collision. A modern seat belt will help to position you properly to gain maximum benefit from your car’s airbags that will inflate（使充气）during a collision. Using a seat belt also prevents you from being ejected (弹出) from a car into the path of oncoming traffic. Research shows that when you wear a modern seat belt, you reduce the risk of death or serious injury by 70% or more during an auto accident.

       Seat belts have existed in different forms since the early days of automobiles, and they have changed from a single lap belt to the three-point seat belt we use today. In 1911 the first airplane seat belt was installed. Then, in the 1920’s they were used in racecars. By the 1930s, a group of American physicians created lap belts for their own vehicles and urged vehicle manufacturers to provide seat belts on all vehicles.

       Dr. C. Hunter Shelden made a major contribution to our safety with his article in the November 5, 1955 Journal of the American Medical Association (JAMA). He strongly encouraged the manufacture and use of door locks, airbags, and retractable(伸缩式的) seat belts, like the ones we use today. The modern three-point seat belt, including a lap belt and a shoulder belt, was introduced as standard equipment on Volvo cars in 1959.

       In 1970, the state of Victoria in Australia made the wearing of a seat belt compulsory for every car driver and front-seat passenger. Today many countries have also mandated(授权) the use of five-point safety harnesses for carefully designed child safety seats that can protect a child during a serious car accident.

       An airbag is a Supplemental Restraint System, or SRS, and consists of a rapidly inflatable restraint cushion that works together with a seat belt to protect you during a collision. Modern cars often contain several airbags in various locations. Since airbags can only inflate once and will quickly deflate after the initial impact, they will not provide any protection for you during a secondary collision.

       The inflation of airbag can protect or hurt you. The risk zone for a driver’s airbag is the first 8 centimeters from its pre-inflation location. While driving, you should remain about 25 centimeters from the airbag in the center of the wheel. As a driver, wear your seat belt and make sure children correctly use their seat belts. Failure to wear a seat belt properly means the airbags in your car might injure or even kill you during an accident.

       An essential part of your safe driving skills is the habit of making sure that you and each of your passengers are always properly positioned and wearing a seat belt. There are many wonderful benefits of being able to drive a car, but there are also severe consequences during an accident for anyone who chooses not to wear a seat belt.

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.) . Many 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 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.
