Mothers Against Drunk Driving (MADD) is a nonprofit organization focused on preventing drunk driving, supporting victims of violent crime, and preventing underage drinking. Founded in 1980 by Candy Lightner after her daughter was killed by a drunk driver, MADD has been instrumental in advocating for stricter DUI laws and raising public awareness about the dangers of impaired driving. The organization generates revenue through donations, fundraising events, and corporate sponsorships, which fund their educational programs, victim services, and advocacy efforts.
