how long does alcohol stay in your system before you take a breathalyzer
Starting from this BAC, your body needs almost 14 hours to completely metabolize the alcohol. Of course to pass the breathalyzer in all 50 states, your BAC needs to be under 0.04. A 0.04 will not get you a DWI (driving while intoxicated), but you can be charged with a DUI (driving under the influence). To legally pass the breathalyzer after 12 beers in three hours, you need a little over 11 hours.
