Extensive use of restraint systems installed in cars is the best short-range solution to accident caused injuries and fatalities, but will prevent less then 40% of fatalities and injuries. Three point restraint systems offer limited protection in frontal crashes above 30 mph, and have not been proven to be superior to other systems in nonfrontal modes. Biomechanical studies and actual accidents with air bag restraint system fleet vehicles have demonstrated that air bags offer increased injury and fatality prevention.
