In 1984, the California Friday Night Live (FNL) Program was developed in Sacramento by the California Department of Alcohol and Drug Programs (ADP) and the California Office of Traffic Safety (OTS).
It began as a pilot program dedicated to reducing the number of deaths and injuries caused by teen motorists driving under the influence of alcohol and other drugs.
Today the main focus of the program shifted from one of preventing drinking and driving among teens to one of environmental prevention efforts promoting healthy lifestyles free of alcohol, tobacco, or other substance use.
