Question: What Are the Penalties for a Second Offense Wisconsin OWI?
Answer: A second offense and higher in Wisconsin are considered criminal offenses. For a second offense we'll have mandatory jail time, as will all subsequent offenses. On second offenses there's a minimum jail term of five days and a maximum of six months—and it goes higher with each subsequent offense. For fourth offenses and higher, those could be considered felonies where prison is actually imposed.
