driving is dangerous and mayresult in an accident and SERI-
OUS INJURY or DEATH.

one contributor to the highway
death toll each year. Even asmall amount of alcohol will

tions and judgment. Just one
drink can reduce your ability to
respond to changing conditions

additional drink. Driving while under the influ-
ence of drugs is as dangerous
or more dangerous than drivingunder the influence of alcohol.(Continued)

have a serious accident if you
drink or take drugs and drive. If
you are drinking or taking
drugs, don't drive. Do not ridewith a driver who has beendrinking or taking drugs.Choose a designated driver orcall a taxi.
