Wisconsin Act 210: Major Overhaul of Ignition Interlock Device (IID) Laws

Analysis of 2025 Wisconsin Act 210 (Senate Bill 248)

Wisconsin has enacted a sweeping update to its Ignition Interlock Device (IID) regulations with the passage of 2025 Wisconsin Act 210. This legislation represents a “carrot and stick” approach to drunk driving enforcement: it eliminates traditional waiting periods for occupational licenses for those who install an IID, but it imposes strict, automatic extensions of the IID requirement for any violations or “fails” recorded by the device.

For many drivers, this law will be a double-edged sword. While you can get back on the road sooner after an OWI conviction or refusal, the “compliance-based” monitoring system means that a single failed breath test or a missed rolling retest could add months to your restriction.

Immediate Eligibility for Occupational Licenses

Perhaps the most significant benefit for drivers under Act 210 is the elimination of the “waiting period” for occupational licenses.

• Repeat Offenders: Previously, second and third-time OWI offenders often had to wait 45 days before becoming eligible for an occupational license. Act 210 removes this 45-day wait.
• Refusal Cases: For those who improperly refuse a chemical test (which normally triggers a 30-day wait), eligibility is now immediate upon the installation of an IID.
• The Trade-Off: To take advantage of this immediate eligibility, the driver must strictly comply with the IID order and the driver safety plan.

Automatic 180-Day Extensions for Violations

Act 210 shifts Wisconsin to a “compliance-based” IID model. Under the new Wis. Stat. § 343.301(6), your IID restriction is automatically extended by 180 days for each occurrence of a violation that happens 60 days or more after installation.

What counts as a “Violation”?

• Failed Start: Any attempt to start the vehicle with a BAC of 0.02 or higher.
• Tampering/Circumvention: Any attempt to bypass the device.
• Unauthorized Removal: Taking the device out before the order expires.
• Missed Random Tests: Failure to take a random breath test while driving (unless a digital image proves the driver wasn’t in the car).
• Lockout Mode: Failure to service the device that results in a lockout.

The New Appeal and Rebuttal Process

Because an automatic six-month extension is a severe penalty, Act 210 creates a formal process to challenge reported violations:

• Final Data Download: At the end of your original IID term, you must complete a “compliance-based review” where the provider downloads all data.
• Notice of Extension: If the provider identifies a violation, the DOT will notify you in writing that your restriction is being extended.
• The Rebuttal: You have 15 business days to provide a written rebuttal to the service provider.
• Malfunctions: The DOT must reverse an extension if documentation proves the “violation” was actually a device malfunction.

Motorcycles and “Class M” Restrictions

Act 210 closes a long-standing loophole regarding motorcycles. Under the new law, if you are ordered to have an IID, you are strictly prohibited from operating “Class M” vehicles (motorcycles). Because IIDs are generally not installed on motorcycles, the legislature has decided that IID-restricted drivers simply cannot ride them until their restriction period ends.

Practical Impact on OWI Defense

Act 210 changes the advice we give to clients from day one of an OWI arrest:

• Early Installation is Key: Because waiting periods are gone, installing an IID immediately can save your employment and mobility.
• Zero Tolerance is Real: The 0.02 BAC threshold is extremely low. Mouthwash, certain foods, or “morning after” lingering alcohol can trigger a 180-day extension.
• Data Management: Clients must be diligent about keeping receipts and records of vehicle service or device errors to support a future rebuttal.

Key Takeaways from Wisconsin Act 210

• No More Waiting: Occupational license eligibility is now immediate upon IID installation for most OWI and Refusal cases.
• 180-Day Penalty: Each “fail” or tampering event adds 6 months to your IID requirement.
• Motorcycle Ban: You cannot ride a motorcycle while under an IID order.
• Compliance Review: Your requirement doesn’t end until a final data download proves you’ve been “violation-free.”
• Increased Criminal Penalties: Tampering with or failing to install an IID now carries increased fines ($350–$1,100) and mandatory jail time (5 days to 6 months).

What This Law Means Going Forward

Act 210 makes the IID provider a de facto extension of the Department of Transportation. Your “sentence” is no longer just a set date on a calendar; it is a performance-based requirement. For the defense, this means we will be spending much more time litigating “IID Refusal” hearings and contesting “false positive” data downloads to prevent our clients from being trapped in a cycle of 180-day extensions.
