Remember:

A Blood Alcohol Concentration (BAC) chart is a general guideline only and NOT the sole way to determine someone’s intoxication level.

Other factors to consider when assessing BAC:

Age

Absorption rate

Amount and type of food eaten

Physical health and fitness level

Medications/Drugs

Impairment begins with the first drink.
