Mothers Against Drunk Driving (MADD) is a non-profit organization founded in 1980 whose mission is to eliminate drunk driving and underage drinking. MADD advocates for stricter laws against drunk driving like ignition interlocks for all convicted offenders and mandatory jail time. The organization was started by Candy Lightner after her 13-year-old daughter was killed by a drunk driver. MADD uses various campaigns, advocacy, and education efforts to achieve its goals of preventing drunk driving and underage alcohol use.
