What is the legal blood alcohol concentration (BAC) limit for drivers over 21 in Wisconsin?

In Wisconsin, the legal blood alcohol concentration (BAC) limit for drivers over the age of 21 is 0.08%. This means that if an individual operating a motor vehicle has a BAC at or above this level, they are considered legally impaired and can face charges related to operating while intoxicated (OWI).

The establishment of this limit is based on research indicating that a BAC of 0.08% significantly affects a driver's ability to operate a vehicle safely. At this concentration, impairments in judgment, coordination, and reaction time can occur, increasing the risk of accidents.

Setting the limit at 0.08% helps enforce safer driving practices and deter individuals from driving under the influence of alcohol. It is important for drivers to understand this limit and recognize the legal repercussions of exceeding it to keep themselves and others safe on the road.
