WASHINGTON – A prestigious scientific panel is recommending that states significantly lower their drunken driving thresholds as part of a blueprint to eliminate the "entirely preventable" 10,000 alcohol-impaired driving deaths in the United States each year. The U.S. government-commissioned, 489-page report by a panel of the National Academies of Sciences, Engineering and Medicine released Wednesday throws the weight of the scientific body behind lowering the blood-alcohol concentration threshold from 0.08 to 0.05. All states have 0.08 thresholds. A Utah law passed last year that lowers the state's threshold to 0.05 doesn't go into effect until Dec. 30. The amount of alcohol required to reach 0.05 would depend on several factors, including the person's size and whether the person has recently eaten.
