Increased Awareness: Groups like Mothers Against Drunk Driving (MADD), founded in 1980, played a crucial role in raising public awareness and advocating for stricter laws. Stricter Laws: The National Minimum Drinking Age Act of 1984, influenced by MADD, compelled states to raise the legal drinking age to 21. Enhanced Enforcement: Lawmakers and police started getting tougher on offenders, leading to a rise in arrests and stricter penalties. Standardized Field Tests: Efforts were made to standardize field sobriety tests for greater consistency in enforcement.
