Approximately 42,000 lives are lost annually on our Nation’s highways. Traffic crashes are the primary cause of debilitating injuries in the United States and the number one killer of Americans under the age of 34. In addition to staggering emotional costs, the annual economic loss to society because of these crashes, in terms of worker productivity, medical costs, insurance costs, etc., is estimated at more than $150 billion. Clearly, there is a need for dramatic improvement in motor vehicle safety.
