Reducing Alcohol-impaired Driving: 0.08% Blood Alcohol Concentration (BAC) Laws
These laws state that it is illegal for a driver’s blood alcohol concentration to exceed 0.08%.

Task Force Recommendations & Findings
The Task Force on Community Preventive Services recommends 0.08% BAC laws based on strong evidence of their effectiveness in reducing alcohol-related motor vehicle crash fatalities.

Task Force findings

Results from the Systematic Reviews
Nine studies qualified for the systematic review.

•Each study evaluated 0.08% BAC laws in one or more of the 16 states that implemented the laws before January 1, 1998.
•Studies reviewed fatal injury crashes (8 studies) and fatal and nonfatal injury crashes (1 study).
•Fatalities due to alcohol-related motor vehicle crashes: median decrease of 7% following implementation of the law (interquartile range: 15% to 4% decrease; 7 studies)
•Potential lives saved per year if all states enact 0.08% BAC laws: 400 - 600 (3 studies)
•No evaluations were found that met the Community Guide economic inclusion criteria.
These results are based on a systematic review of all available studies led by scientists from CDC’s Division of Unintentional Injury Prevention with input from a team of specialists in systematic review methods and experts in research, practice and policy related to reducing alcohol-impaired driving.
