"Since launching this campaign in 1983, more than 68% of Americans exposed to the advertising have tried to prevent someone from driving drunk. In 1998, America experienced its lowest number of alcohol–related fatalities since the U.S. Department of Transportation began keeping records. Campaign taglines have included: 'Drinking & Driving Can Kill A Friendship' and 'Friends Don't Let Friends Drive Drunk.'"
