BAC is the amount of alcohol in a person's body measured by the weight of the alcohol in a certain volume of blood. 

In Tennessee, a drunk driver’s level of intoxication is typically determined by the measurement of blood alcohol content (BAC). A BAC measurement of 0.08% defines the criminal offense.
