Wisconsin’s ignition interlock rules are set to change under a new law known as Act 210. Once it takes effect, finishing an IID order will include a formal compliance review. A single qualifying violation could then add 180 days to your requirement. Here is what the law will do, and what still applies to your order today.
What Act 210 Will Change
Wisconsin signed Act 210 into law in April 2026. It creates a compliance-based model for ignition interlock orders. Once active, drivers will return to their provider at the end of an order for a final data download. That review is where a single qualifying violation can add 180 days to the requirement. Act 210 is not in effect yet. The law has a delayed start date. It will not apply until WisDOT publishes a formal notice and a required waiting period passes.
Until Act 210 takes effect, the current Wisconsin IID process still governs your order. If you are unsure whether the new rules apply to you, WisDOT or your court is the most reliable source.
How the Review and Extensions Will Work
Once Act 210 takes effect, the process will run directly between your IID provider and WisDOT. Your provider will report qualifying events electronically, and WisDOT will decide whether an extension applies.
This is different from how a tampering report is routed during an active order today. That process typically goes through the county where you were convicted. The end-of-program compliance review will be a separate, state-level process.
Events That Will Be Able to Trigger an Extension
Once the law is active, several kinds of events will be able to add 180 days to an order. This applies to events reported 60 days or more after installation:
- A failed start attempt: trying to start the vehicle with a breath result at or above 0.02 BAC.
- A missed rolling retest, regardless of the reason it was missed.
- Tampering, circumvention, or unauthorized removal of the device.
- A missed service appointment that causes the device to enter lockout.
The law also covers a failed confirmation retest. WisDOT can reverse an extension if a service provider confirms the event was a device malfunction.
What This Means for Attorneys and Referral Partners
Act 210 will matter for anyone managing a client’s IID timeline, but it is not active yet. Advising a client under the new extension rules before the effective date could create confusion. It could also risk a missed deadline under the rules that still apply today.
Once Act 210 is active, the rebuttal window will be 15 business days from the date of WisDOT’s written notice. Rebuttals will go to the service provider. The provider reviews documentation such as proof of a device malfunction or a non-driver incident.
We track the effective date closely and will update this page as soon as Act 210 is active. If you are referring clients and want to confirm current status, visit our Support page or reach out directly.
What Still Applies to Your Order Today
For now, Wisconsin’s current IID process still governs your order. Complete your program and verify your eligibility date with WisDOT or your court. Then schedule your removal once that date is confirmed.
Once Act 210 takes effect, the compliance review will add a new step at the end of that process. We will share an update the moment the law becomes active.
