Some attribute the slight rise in fatal auto accident statistics to the increase in state speed limits that have gradually occurred over the last twenty years. Despite the increased usage of seat belts, car seats, and air bags, thousands of people still die in auto accidents each year in the United States, as well as worldwide. While some fatal auto accidents are purely accidents, and caused by the decedent himself or herself, other fatal auto accidents are directly due to the negligent, reckless, careless, or even intentional acts of another person, or a number of persons. For example, when a drunk driver strikes and kills a pedestrian, he or she is most likely liable for the wrongful death of the pedestrian. Likewise, when a driver is exceeding the speed limit by 20 mph, and strikes another vehicle, causing the death of its occupants, he or she is likely to be found responsible for the wrongful deaths of the car's occupants.
