Mothers Against Drunk Driving is a 501(c)(3) non-profit organization with approximately 2 million members and supporters nationwide. MADD was founded in 1980, and continues to grow 25 years later. We're dads and daughters, sons and uncles, friends and neighbors. And mothers. We're all ages and from all walks of life. We are committed to our mission to stop drunk driving, support victims of this violent crime, and prevent underage drinking. We need more people like you to continue making a difference.
