Do Seat belts and Air Bags Reduce Mortality and Injury Severity After Car Accidents?

Over the past 30 years mortality from motor vehicle collisions (MVCs) has steadily declined, a trend attributed to the effectiveness of car safety devices. Using data from the National Trauma Data Bank, researchers studied 184,992 patients between 1988 and 2004. Variables examined included whether car safety devices were used in MVCs, such as wearing a seat belt or the deployment of an airbag, or not. Using the group of patients who employed no devices as a baseline, the data illustrated that those who used seat belts and air bags together had the greatest mortality reduction. The data also indicated that mortality rates were increased when seat belts or air bags were used alone rather than in conjunction with one another.
