The Network of Employers for Traffic Safety (NETS), a nonprofit organization comprising corporate, state, and federal partners, is sponsoring the fourth annual Drive Safely Work Week during September 11--15, 2000. Unintentional injuries are the leading cause of death in the United States for persons aged 1--44 years and accounted for approximately 97,000 deaths among persons of all ages in 1997 (1). In 1998, approximately 41,000 persons died on U.S. highways and another 3.2 million suffered nonfatal injuries (2). Highway fatalities have decreased substantially since 1966 (n=50,984), and the fatality rate per mile of travel has decreased more than threefold (from 5.5 in 1966 to 1.6 in 1998) (3). However, minimal changes have occurred in the numbers of fatalities and the fatality rate per mile from 1994 to 1998. Although most injuries and fatalities in 1998 were to vehicle occupants, pedestrians accounted for 5220 of the fatalities and 69,000 of the injuries (4). Motor-vehicle crashes also are the leading cause of occupational injury deaths, accounting for approximately 16,000 deaths in workers from 1980 to 1992, or 20% of all fatal workplace injuries over this period (5). The national campaign to prevent motor-vehicle crashes includes a "toolkit" that contains information, posters, and suggested programs that employers or other groups can use to address five major traffic safety issues: safety belt use, aggressive driving, driver inattention, sharing the road with trucks, and impaired driving. The materials are not dated and may be used throughout the year.
