Why Wisconsin Charges Both OWI and PAC From One Stop

Attorney Answer

Charging both is not a mistake and it is not double-charging you — Wisconsin's statute expressly allows it, requires the counts to be tried together, and directs that if you are found guilty of more than one, it counts as a single conviction for sentencing.

The statute. Wis. Stat. sec. 346.63(1)(c) is the provision that answers your question. It provides that a person may be charged with, and a prosecutor may proceed on a complaint based on, a violation of any combination of paragraph (a) (operating while under the influence), paragraph (am) (a detectable amount of a restricted controlled substance), or paragraph (b) (prohibited alcohol concentration) for acts arising out of the same incident or occurrence; that if a person is charged with any combination of them the offenses shall be joined; and that if the person is found guilty of any combination of them for acts arising out of the same incident, "there shall be a single conviction for purposes of sentencing and for purposes of counting convictions under ss. 343.30 (1q) and 343.305."

Both counts are permitted because each requires proof of a fact the others do not. Paragraph (a) is about impairment — whether you could safely operate the vehicle — and does not depend on a number. Paragraph (b) is about the number itself and does not depend on proof that you drove badly. A .10 result supports the PAC count directly; the OWI count rests on the driving, the officer's observations, and the field testing.

Read the single-conviction rule precisely. It is a treatment rule — one conviction for purposes of sentencing and for counting prior convictions. It is not a statement about what a judgment document will say. If your real worry is how this appears on your record, ask your lawyer specifically what the judgment of conviction will read; that is a narrower question than the one sec. 346.63(1)(c) answers.

The obstruction count is separate. Resisting or obstructing an officer is not part of the OWI scheme and is not joined or merged by sec. 346.63(1)(c). It stands on its own elements and carries its own penalty. Do not assume it rises or falls with the OWI case.

What you can do 1. Read the charging document count by count and note which paragraph letter each OWI-related count cites — (a), (am), or (b). That tells you exactly what the State says it must prove. 2. Find the paperwork you were given about your driver's license. It is a different document from the criminal citation and it has its own deadline printed on it. 3. Get a Wisconsin defense lawyer and ask specifically about the joinder requirement and single-conviction treatment in sec. 346.63(1)(c), and what the judgment will say. 4. Have counsel request discovery early — squad and body camera video, the observation period before testing, the instrument's calibration and maintenance records, and the officer's report on the obstruction allegation. 5. Say nothing further about the obstruction facts to anyone but your lawyer. That count often turns on a few seconds of the stop, and your own later description of it can become the State's evidence.

⏱ Time limits apply — and the license deadline comes first. The administrative suspension that follows a prohibited-alcohol-concentration result runs on its own short clock, measured in days from the notice handed to you at the time of arrest. Check that notice today; the window can close weeks before your first real court date, and once it does, it is gone. These are two separate tracks: the license case and the criminal case use different standards of proof and can reach opposite results on the same stop. Beating the criminal case does not undo a suspension you never contested, and losing the license hearing does not decide the criminal case.
