What Are Wisconsin's Laws Regarding OWI?
If you are arrested with a blood alcohol content (BAC) of .08, you are "per se" intoxicated and no proof of bad driving or other signs of intoxication are necessary. If you have a BAC less than .08, you can be convicted of OWI if there is other evidence of intoxication, such as crossing the center line, hitting another car or failing field sobriety tests. If you are under age 21, Wisconsin has a zero tolerance policy. If your BAC is greater than 0.0 you could be charged with OWI.
