Alcohol use disorder affected 1.46 billion people worldwide in 2019, about 1 in 5. Alcohol is linked to roughly 13% of road traffic deaths globally, tying widespread exposure to large-scale preventable losses. For prevention, ignition interlocks reduce drunk driving recidivism by about 70% across study syntheses, showing what policy and enforcement can change when implemented.
