Seat belts save lives. The latest reminder is the rollover of a vehicle carrying six young people near Waverly, Neb. A 15-year-old died, and the Lancaster County sheriff says none of the youths was wearing a seat belt. Federal statistics show that seat belts reduce serious crash-related injuries and deaths by about 50 percent. The numbers also show that those aged 18-34 are less likely to wear them. More buckled seat belts mean fewer tragic outcomes.
