The Pledge for Life was modified from the Contract for Life, created by Students Against Destructive Decisions (SADD). Created by Dr. John Knight and his team in 2016, the Pledge is designed to keep teens and young adults (age 18+) safe from driving after drinking, accepting a ride from an impaired driver, or walking home alone. It asks them to identify 3 friends or family members willing to serve as a “committed other” who agrees to help them get home safely if called.
