Never use illegal drugs. Illicit drugs are involved in a large proportion of traffic fatalities.
Never drive when fatigued. The dangers posed when fatigued are similar to those when intoxicated. A drunk or fatigued driver has slowed reactions and impaired judgment. And a driver who nods off at the wheel has no reactions and no judgment! Drivers who drift off cause about 72,500 injuries and deaths each and every year.
Don't use a car phone, put on make-up, comb your hair, or eat while driving. Drivers using cellular phones are four times more likely to have an accident than other drivers.
Steer clear of aggressive drivers. Aggressive drivers may be responsible for more deaths than drunk drivers.
