After having a drink or two at happy hour or when you're leaving a party it can sometimes be difficult to determine exactly how much the alcohol you've consumed has affected you. You may feel completely able to drive yourself home but in the event of a traffic stop you may find yourself facing a breathalyzer test or charges of driving while intoxicated.
A recent event held in Missouri was aimed at clearing up some of that ambiguity for the state's motorists. The Columbia Police Department hosted a DWI/alcohol education event where people who had been drinking could come blow into a breathalyzer to find out what effect the alcohol they consumed had on their blood alcohol content, or BAC. In Missouri a person is presumed to be intoxicated if he or she has a BAC of 0.08 percent or higher.
