In road accidents, airbags can help save lives and prevent injuries. According to Transport Canada, airbags helped prevent about three hundred deaths over a ten-year period. In addition, a U.S. National Highway Traffic Safety Administration study has found that, together with seat belts, airbags can help reduce injuries up to 75 percent, especially for the head and chest. As these areas of the body contain the brain, lungs, and heart, the most important organs necessary for life, protecting them is essential.
