Your blood alcohol concentration can be measured by testing breath, blood or urine. Most states have adopted BAC laws that make it illegal to drive with a BAC at or above a set amount. Most states have adopted 0.08% as the highest allowable concentration. Though you may still be found to be intoxicated even if your BAC is below this amount.
