In the state of Wisconsin, it is illegal to operate a vehicle if your BAC is over the legal limit of 0.08%. This legal limit can be even lower for certain people such as commercial drivers or those who are under twenty-one years of age.

Although there is no exact formula for calculating BAC, you can estimate it based upon body weight and number of drinks. For example, for a woman who weighs 120lbs and has two drinks, she will be at a BAC of 0.08%. This would mean she is over the legal limit to drive in Wisconsin and could be charged with an OWI.

Everyone absorbs and metabolizes alcohol differently, therefore men’s and women’s BAC charts are different. You should not rely on these charts for complete accuracy on whether to drive. There are other factors that can contribute to impairment such as fatigue, medications, amount of food consumed, and how quickly you consumed the alcohol.

If you have been drinking, it is best not to drive and find another way to get to your destination. Whether you have a designated driver or decide to hire an Uber or taxi service, anything is better than driving while impaired.
