Definition: A Latin phrase that means "by itself." Per se drunk driving laws state that someone is guilty of driving under the influence if their blood alcohol content is at a certain level (.08 in all 50 states). Drivers with a BAC at or above .08 are intoxicated in the eyes of the law and no additional proof of impairment is necessary to obtain a conviction.
Also Known As: Per Se BAC Laws
Examples: Under the state per se law, a BAC of .12 is by itself proof of driving while intoxicated.
