Know Your Limits, Know the Law
The current legal blood alcohol concentration (BAC) limit for driving in the United States is .08 percent. To put that impairment in perspective, research shows talking on a hands-free cellphone impairs drivers to the same degree as driving at the .08 legal limit.
The National Transportation Safety Board, Centers for Disease Control and Prevention, American Medical Association, and other organizations, support lowering the legal limit from .08 to .05. But will lowering the legal limit actually stop drunk drivers from getting behind the wheel?
A woman can reach the .05 legal limit with as little as one drink. Instead of deterring the most dangerous drivers from getting behind the wheel while heavily intoxicated, a .05 legal limit discourages responsible drinkers from having a single drink with dinner before getting behind the wheel.
