In the United States, it is illegal to drive or operate heavy machinery while intoxicated, and authorities rely on BAC values to determine the level of intoxication in suspects. The BAC (blood alcohol content), which is also referred to as the BAL (blood alcohol level), is the total ratio of alcohol in a person’s body to his or her blood volume, with the legal limit in all states being 0.08.  This infographic explains the basics of BAC, how it is calculated, and its practical applications. If you have been arrested for a DUI, speak to a criminal defense attorney to discuss your options and protect your rights.
