NEVER drink or take drugs and
drive.
Drinking or taking drugs and
driving is dangerous and may
result in an accident and SERI-
OUS INJURY or DEATH.
Drunk driving is the number
one contributor to the highway
death toll each year. Even a
small amount of alcohol will
affect your reflexes, percep-
tions and judgment. Just one
drink can reduce your ability to
respond to changing conditions
and emergencies and your reac-
tion time gets worse with each
additional drink.
Driving while under the influ-
ence of drugs is as dangerous
or more dangerous than driving
under the influence of alcohol.(Continued)
WARNING (Continued)
You are much more likely to have
a serious accident if you drink or
take drugs and drive. If you are
drinking or taking drugs, don’t
drive. Do not ride with a driver
who has been drinking or taking
drugs. Choose a designated
driver or call a taxi.
