* Traffic crashes are the leading cause of workplace deaths, accounting for
1,347 (23.5 percent) of civilian worker deaths in 2000, according to the
National Institute for Occupational Safety and Health. More than half of these
victims were not wearing seat belts at the time of the crash. 
* Only 75 percent of drivers wear seatbelts. In fatal crashes, 30 percent
of occupants not wearing seatbelts are ejected from the car and 73 percent of
them are killed. But only 1 percent of occupants wearing seatbelts are ejected
in crashes. [11, 14]
*Most seat belt laws apply only to front-seat passengers. However, when
back-seat passengers don’t use seat belts, they not only endanger themselves but
can increase risk of death or injury to front seat passengers by 20 percent.
Teenagers have especially high crash risk but low seat belt use.
