The amount of alcohol in a person’s body is measured by the weight of the alcohol in a certain volume of blood. This is called the blood alcohol concentration or BAC. BAC measurements provide an objective way to identify levels of impairment, because alcohol concentration in the body is directly related to impairment.
Each standard drink raises a person's BAC but to what degree depends on several factors. When you hear the word BAC think numbers not how someone should feel. BAC is determined in the form of numbers. For example, a BAC of a .08 is the drunk driving standard in Michigan. This means that a person can be issued a drunk driving ticket with this amount or higher. If someone is below a BAC of a .08, he/she can still be issued a ticket if the police officer determines that the person is unsafe to drive.
There are several factors that can effect your BAC.
