Lowering BAC limit?

Every day in the United States, 29 people die and many more are hurt in alcohol-related traffic accidents. But we could lower those numbers by lowering the drunken-driving threshold, according to a prestigious scientific panel. Right now, drivers across the country are prohibited from driving with a blood alcohol concentration, or BAC, at .08 or above. A government-commissioned report from the National Academies of Sciences, Engineering and Medicine suggests lowering the BAC legal limit to .05.
