In addition, the odds ratio for being involved in a crash increases significantly at a BAC of 0.05 percent.57 Currently, all U.S. states specify a BAC of 0.08 percent as the cutoff for operating a motor vehicle under the influence of ethanol.58 Because of the rising concern about alcohol-related motor vehicle crashes involving people under the age of 21, all states have adopted zero-tolerance laws for underage drinking that make it a criminal offense if drivers under the age of 21 are found to have a BAC between 0.00 and 0.02 percent.59,60 While legislation has helped to establish BAC limits over the past 30 years, nearly 31 percent of all traffic-related deaths (10,076) in 2013 involved an alcohol-impaired driver with a BAC of 0.08 percent or more.61.
