If you are convicted of a 4th OWI in Wisconsin, your license will be permanently revoked if the offense occurred within 15 years of your last OWI. This law is due to the 2018 enactment of State Senate Bill 135. The enactment of this legislation proves that Wisconsin OWI laws are getting increasingly stricter. In the face of a 4th OWI charge, or any OWI charge, experienced legal counsel is paramount. Having a drunk driving citation or charge on your record can significantly impact your future.
