If you have just been arrested for a second time for operating while intoxicated in Waukesha County, Milwaukee, or one of the surrounding communities, the ground feels very different than it did the first time — and it should. In Wisconsin, a first-offense OWI is not a crime. A second one usually is. That single shift, from a ticket to a criminal charge, changes everything about what is at stake and how the case has to be handled.

In Wisconsin, a first OWI is a ticket — a second is a crime

Wisconsin is unusual among the states in treating a standard first-offense OWI as a civil forfeiture rather than a crime. It is handled much like a serious traffic ticket: a fine, a license revocation, an alcohol assessment, but no jail exposure and no criminal record from the forfeiture itself.

A second offense is a different animal. It is charged as a criminal misdemeanor under Wisconsin’s operating-while-intoxicated statute (Wis. Stat. § 346.63), which means jail exposure, a criminal record if convicted, and the collateral consequences that follow a criminal conviction — employment questions, professional licensing, and more. The companion “PAC” charge, for driving with a prohibited alcohol concentration of 0.08 or above, is typically filed alongside it, exactly as in a first case.

The ten-year line that turns a ticket into a crime

Whether a new OWI is charged as a criminal second offense often turns on timing. Wisconsin law directs how prior offenses are counted (Wis. Stat. § 343.307), and for the jump from a civil first to a criminal second, the key question is generally whether the prior OWI falls within a ten-year window.

Put simply: if your prior OWI conviction is within ten years of the new arrest, the new charge is generally treated as a criminal second offense. If more than ten years have passed since that first offense, a new OWI is, in many cases, treated as a first-offense forfeiture again. This ten-year line applies to the second-offense question specifically; third and subsequent offenses are counted differently, and certain factors — such as a prior offense involving injury — can change the analysis. Because the counting rules carry real exceptions, how your priors are counted is one of the first things worth having a lawyer examine.

What a criminal OWI conviction carries

A second-offense conviction is penalized under Wisconsin’s OWI penalty statute (Wis. Stat. § 346.65), and the consequences are more serious across the board than a first offense. They generally include mandatory minimum jail time set by statute, a fine, a driver’s license revocation, an ignition interlock device requirement, and an alcohol and other drug assessment (the AODA assessment) that drives a required treatment or education plan. The license consequences run through Wisconsin’s revocation and implied-consent provisions (Wis. Stat. §§ 343.30 and 343.305).

The exact numbers — how many days, how large a fine, how long a revocation — are set by statute and depend on the specifics of your case, including your blood-alcohol concentration and any aggravating circumstances. Those figures also change as the legislature amends the statutes, which is precisely why a general article like this one should never be mistaken for advice about your own case. The point to take from it is the shape of the exposure, not a promise about the penalty.

Why the second case is where the defense work matters most

Because a second offense is criminal, the tools available to the defense are the tools of a criminal case. Whether the traffic stop was lawful, whether the field and chemical testing were properly conducted, and whether the State can prove operation and impairment are all live questions. So is the counting itself: whether a claimed prior was correctly counted, whether it falls inside the ten-year window, and whether it was a valid conviction in the first place. A prior that should not count can be the difference between a criminal charge and a civil one.

None of that happens on its own. It requires someone who reads the reports, the statute, and the record with the specific goal of finding where the State’s case is weakest — and who understands that on a second offense, the difference between a good and a bad outcome is measured in your record, your license, and your freedom.
