Mothers Against Drunk Driving (MADD) is a nonprofit organization in the United States and Canada that seeks to stop drunk driving, support those affected by drunk driving, prevent underage drinking, and strive for stricter impaired driving policy, whether that impairment is caused by alcohol or any other drug. The Irving, Texas–based organization was founded on September 5, 1980, in California by Candace Lightner after her 13-year-old daughter, Cari, was killed by a drunk driver. There is at least one MADD office in every state of the United States and at least one in each province of Canada. These offices offer victim services and many resources involving alcohol safety. MADD has claimed that drunk driving has been reduced by half since its founding. According to MADD's website, 'The mission of Mothers Against Drunk Driving is to end drunk driving, help fight drugged driving, support the victims of these violent crimes and prevent underage drinking.' Generally MADD favors strict policy in a variety of areas, including an illegal blood alcohol content of .08% or lower and using stronger sanctions for DUI offenders, including mandatory jail sentences, treatment for alcoholism and other alcohol abuse issues, ignition interlock devices, and license suspensions; maintaining the minimum legal drinking age at 21 years; mandating alcohol breath-testing ignition interlock devices (IIDs) for everyone convicted of driving while legally impaired. MADD's founder Candace Lightner left the group in 1985. In 2002, as reported by The Washington Times, Lightner stated that MADD 'has become far more neo-prohibitionist than I had ever wanted or envisioned … I didn't start MADD to deal with alcohol. I started MADD to deal with the issue of drunk driving'. Author Susan Cheever and the SAGE Encyclopedia of Social Problems have said MADD is a manifestation of the temperance movement. MADD 'supports a substantial increase in taxation on alcoholic beverages as a means of covering the cost to society caused by misuse of alcohol'. MADD 'advocates that schools and other organizations hosting social and athletic gatherings for youth take positive steps to ensure that alcoholic beverages not be present at those gatherings'. On May 3, 1980, Cari Lightner, a 13-year-old girl, was killed by a drunken hit-and-run driver at Sunset and New York Avenues in Fair Oaks, California. The 46-year-old driver, who had recently been arrested for another DUI hit-and-run, left Cari's body at the scene. Cari's mother, Candace (Candy) Lightner, organized Mothers Against Drunk Driving and subsequently served as its founding president. A 1983 television movie about Lightner garnered publicity for the group, which grew rapidly. In the early 1980s, the group attracted the attention of the United States Congress. Senator Frank Lautenberg (D-NJ) did not like the fact that youth in New Jersey could easily travel to New York to purchase alcoholic beverages, circumventing New Jersey's law restricting consumption to those 21 years old and older. The group had its greatest success with the enacting of a 1984 federal law, the National Minimum Drinking Age Act, that introduced a federal penalty (a 5%—later raised to 10%—loss of federal highway dollars), for states that did not raise the minimum legal age for the purchase and possession of alcohol to 21. After the United States Supreme Court upheld the law in the 1987 case of South Dakota v. Dole, every state and the District of Columbia made the necessary adjustments by 1988 (but not the territories of Puerto Rico and Guam). However, in July 2010 Guam raised its drinking age to 21.
