The best plan is to designate a sober driver any time you are celebrating with alcohol. A sober driver is someone who has not had anything to drink.
This blood alcohol concentration (BAC) calculator will estimate your blood alcohol level.
Your BAC level is based on a complex interaction of weight, gender, alcohol consumed and time. Any amount of alcohol will impair your ability to drive.
For this calculator, one drink is considered to be equal to 12 oz. of beer, 5 oz. of wine or 1.5 oz. of hard liquor.
Calculations are estimates based on Missouri law and are not sufficient evidence to be considered legal evidence.
