NTSB Most Wanted List Roundtable .05 BAC, Part 1: Past, Present, and Future

​It’s been nearly a decade since NTSB recommended that all 50 states lower their BAC limit from .08 to .05 in our 2013 report, Reaching Zero: Actions to Eliminate Alcohol-Impaired Driving. Why did we do that, and how has it improved safety since then? In Part 1 of this virtual roundtable series, hosted by NTSB Member Tom Chapman, we will discuss the history of this safety recommendation, explore international laws and data, proposed legislation in the United States, and evaluation results from a NHTSA study of Utah’s .05 BAC law, which took effect December 30, 2018. Prevent Alcohol- and Other Drug-Impaired Driving​ is on our 2021-2022 Most Wanted List of Transportation Safety Improvements.
