Under the new legislation, drivers will be considered impaired at a blood alcohol content, or BAC, of 0.05 percent. The space above a bar itself has become a legal battleground; under current Utah law, establishments must erect physical barriers, nicknamed “Zion curtains,” to prevent patrons from watching bartenders mix drinks. The reasoning is straightforward: Lower blood alcohol levels decrease the odds of a fatal accident. The odds double again as blood alcohol levels increase from 0.05 to 0.08. France, Italy, Russia and Australia, not known for a lack of drinking culture, all have thresholds at 0.05 BAC or lower.
