If you are facing a Wisconsin OWI or refusal hearing in 2026, the rules around your ignition interlock device and your ability to keep driving have just changed. 2025 Wisconsin Act 210 was signed by Governor Tony Evers on April 8, 2026 and published April 9, 2026. It is the largest single change to Wisconsin IID law since the 2010 Act 100 framework.
It is also a double-edged sword. On one side, it eliminates two waiting periods that have constrained Wisconsin drivers for decades. On the other, it adds a 180-day extension trap, a new criminal IID-violation offense, and a motorcycle ban that nobody is talking about.
Here is what every Racine, Kenosha, and Walworth County driver actually needs to know.
The Headline: 30 Days and 45 Days Are Gone
Pre-Act 210, two waiting periods kept Wisconsin drivers off the road even after they had agreed to the IID and the SR-22 financial-responsibility filing:
- 30 days after a first-offense refusal under Wis. Stat. § 343.305(10)(b)2.
- 45 days after an OWI revocation under § 343.30(1q)(b)3 and (b)4.
Act 210 eliminates both. The new statutory language replaces the 30-day wait with eligibility “upon installation of an ignition interlock device on any motor vehicle that the person operates,” and amends the OWI subsections to delete the 45-day language entirely. Once Act 210 is operative, a refusal defendant or OWI defendant who installs the IID and files the SR-22 will be eligible for an occupational license the same day. The general 15-day baseline at § 343.10(2)(a) is unchanged, but the extra 30 and 45 days are gone.
For first-offense defendants, that is the most consequential pro-defendant change to Wisconsin OWI law in a decade.
The Catch: Act 210 Is Not Yet in Effect
This is the part that has not made it into most reporting. Section 17(2) of Act 210 delays the effective date of the substantive IID and occupational-license provisions to “the first day of the 12th month beginning after” a notice WisDOT publishes in the Wisconsin administrative register. As of May 2026 that notice has not yet been published.
The realistic effective date is therefore 2027 at the earliest. Until WisDOT publishes the implementation notice and the 12-month delay runs, the existing 30-day and 45-day waiting periods, the existing IID-violation framework, and the existing § 347.413 IID-violation penalties all stay in force.
If you are facing a Wisconsin OWI or refusal hearing today, the old rules govern. If you are advised that the new rules apply, ask your attorney to verify against the current WisDOT administrative register notice.
The Trap: 180-Day Extensions With Six Triggers and No Cap
Once Act 210 takes effect, the new § 343.301(6)(b) imposes a 180-day extension to your IID period for each occurrence of any of six specified events, when the event occurs 60 or more days after IID installation:
- Tampering with or attempting to circumvent the device.
- Unauthorized removal.
- Failure to service that results in lockout.
- Any attempt to start the vehicle with breath alcohol of 0.020 or higher.
- Failure to take a random retest, unless the device’s digital image confirms the vehicle was unoccupied.
- Failure to pass a confirmation retest.
There is no statutory cap on extensions visible in the Act text. Two triggering events 60 days apart stack to 360 additional days. Three events stack to 540 days. The math compounds quickly.
The 0.020 Threshold Will Catch Innocent Conduct
Trigger four uses a 0.020 BrAC threshold. That is one-quarter of the standard 0.08 OWI limit and about half of the 0.04 commercial-driver limit. Mouthwash, cough syrup, fermented foods, and trace residual alcohol from the previous evening can all produce a 0.020 reading. The interlock device does not distinguish between actual consumption and incidental positive readings, and Act 210 does not distinguish either. After the 60-day grace window, every 0.020 start attempt is a potential 180-day extension.
If you are on IID, switch to alcohol-free mouthwash, read every cough-syrup label, and assume the device is unforgiving.
The Random-Retest Camera Exception
Trigger five is the most defensible of the six. The Act carves out missed retests where the device’s digital image (most modern interlocks include a camera) confirms the vehicle was unoccupied. If you missed a retest because you had stepped away from the vehicle, preserve your own records of vehicle occupancy and request the digital-image data through your service provider promptly. The new compliance-review framework gives the service provider only seven business days from final data download to act, so timing matters.
The Sleeper Provision: A New Misdemeanor Crime Under § 343.302
This is the change Act 210’s coverage has almost universally missed. Act 210 renumbered the prior IID-violation provision at § 347.413 into a new § 343.302 and added a new subsection (2) with criminal penalties:
§ 343.302(2): Fine of not less than $350 nor more than $1,100, plus imprisonment for not less than 5 days nor more than 6 months.
That penalty range is structurally identical to a 2nd-offense OWI misdemeanor.
Stop and absorb that. A driver who is on IID for a 1st-offense refusal (which under Wisconsin law is a civil revocation, not a criminal conviction) can now face actual jail exposure under § 343.302 if charged with an IID-violation offense. A defendant who took the civil path on the underlying refusal can end up criminally convicted on the IID side.
This is the single most material structural change in Act 210, and it dramatically raises the stakes of every IID compliance issue from the day the Act takes effect.
The Motorcycle Ban
Act 210 also amends § 343.301(1g)(am)1 to prohibit operation of a Class M (motorcycle) vehicle for the entire duration of the IID order. The statutory text contains no carve-out for drivers who hold only a Class M license, and no carve-out for off-season storage.
Wisconsin has roughly 320,000 registered motorcycle endorsements. Drivers who use motorcycles for primary or seasonal transportation, or who own multiple bikes for cross-country touring, will need to plan for the IID-period gap. There is no apparent way to install an IID on a motorcycle that is consistent with vehicle safety, and Act 210 does not require that there be one. The simpler answer the Act adopts: no Class M operation while on IID.
The Bigger Picture
Act 210 is best understood as a front-end-easier, back-end-harder trade. Wisconsin drivers face fewer barriers to getting an occupational license after a first OWI or refusal, but the consequences for stumbling once the IID is installed are significantly worse. Six triggers, 180 days each, no visible cap, plus a new criminal pathway, plus a motorcycle ban.
For first-time defendants who can comply cleanly, this is a meaningful pro-defendant reform. For defendants who are realistic about the difficulty of perfect IID compliance over a 12-to-18-month order, the new framework is harder, not easier.
What to Do Right Now
Three concrete steps for anyone facing a Wisconsin OWI or refusal in 2026:
- Verify what version of the law applies to your case. Until WisDOT publishes the administrative notice and the 12-month clock runs, the old 30-day and 45-day waits and the old IID-violation framework still apply. Don’t budget for the new rules until your attorney confirms the operative date.
- If your case will fall under Act 210, plan for same-day occupational-license filing. Schedule the IID installation at a state-approved vendor in advance. File the SR-22 with your insurer before the conviction or revocation date. The new rules reward speed.
- Once on IID, treat compliance as criminal-grade. The new § 343.302 misdemeanor pathway means an IID violation can produce jail exposure even when the underlying conviction did not. Switch to alcohol-free mouthwash. Read every cough-syrup label. Preserve records of vehicle occupancy. Take every random retest.
