Despite improved road and auto safety, car crashes on America’s roads continues to result in a staggering number of deaths and take a mounting financial toll. In 2006, the American Automobile Association (AAA) reported that automobile crashes cost the U.S. $164.2 billion a year. This total is more than twice the actual cost of traffic congestion. The study also noted that 42,642 people died in such accidents in 2006, which equals to about 117 deaths in a day and almost 5 per hour. While the National Highway Safety Transportation Administration (NHSTA) announced fewer deaths in 2007 and 2008 as the result of traffic accidents, they are still the single largest source of fatalities and injuries in America from any single cause.
