GAINESVILLE, Fla., June 10 (UPI) -- Thirty-five percent of people in U.S. bars who said they were designated drivers had blood-alcohol levels high enough to impair their driving, researchers say.
Adam Barry, an assistant professor of health education and behavior at the University of Florida, and his team recruited patrons as they left bars in a restaurant and bar district of a major university town in the Southeast between 10 p.m. and 2:30 a.m. across six Friday nights before home football games in fall 2011.
