This involves setting standards or establishing parameters for appropriate behavior, and they also establish clear penalties or consequences for violating these standards. For example, in October, 2000, Congress adopted a .08 blood-alcohol level as the national standard for drunken driving—a significant change from the 0.10 limit most states had in place at that point. The new standard was established based on research establishing a relationship between lower blood-alcohol levels and reductions in impaired driving incidence, alcohol-related crashes, and traffic deaths.5 In many States, drivers whose blood alcohol levels exceed these legal standards will immediately lose their licenses.
Some examples of policies to deter underage drinking include:
- Dram shop liability
- Social hosting liability laws
- 0.08% Blood Alcohol Content (BAC) laws
- Lower BAC laws for young drivers
- Graduated drivers' licensing laws
- Open house assembly ordinances
- "Cops in shops"
