What Wisconsin requires
Wisconsin does not order an interlock for every first offense — it kicks in at 0.15% BAC, on a refusal to give a sample, or on any repeat OWI. What catches people out is the clock: your term does not start until the DMV actually issues you a license, so you cannot sit it out.
- First offense: Minimum 12 months, counted from the day a license is issued — ordered only at 0.15% BAC or higher, or on refusal
- Lockout threshold: 0.02% — under an IID order you may not drive above that, far below the 0.08% limit
- Program run by: The convicting court, with the order enforced by Wisconsin DOT / DMV
Why Wisconsin orders these devices
An interlock order is not a judgment about you personally — it is what the state does with every case of this kind, and the reason sits in the crash record.
Source: NHTSA Fatality Analysis Reporting System, 2020–2022. The count covers fatal crashes where police recorded that a driver had been drinking, which is narrower than the federal 0.08 BAC measure and therefore understates the real figure. Lafayette County runs at or below the Wisconsin average — the requirement is set state-wide regardless. What the device changes is measurable too: a car fitted with one cannot be started over the limit, which is why the order attaches to driving privileges rather than to the sentence.

Interlock questions in Shullsburg
Where can I get an ignition interlock device installed in Shullsburg, WI?
We index 1 certified installation point in Shullsburg, run by Intoxalock. Addresses are listed above. Book with the provider your paperwork names, not the nearest one — a device approved in one state is not automatically approved in the next, and switching brands mid-term means a second installation fee.
How much does it cost to have an ignition interlock device installed in Wisconsin?
Wisconsin does not publish a price, so the honest answer is the national one: NHTSA puts installation at $70 to $90 and monitoring at about $70 a month, roughly $3 to $4 a day. Quotes in Shullsburg will sit around that unless the provider is charging for something the state does not require.
Can I drink one beer and still start the car in Wisconsin?
Almost certainly not. 0.02% — under an IID order you may not drive above that, far below the 0.08% limit That is far below any drunk driving limit, which is the point: the device is not testing whether you are impaired, it is testing whether you drank. One drink shortly before a test is enough on most programs, and the fail is recorded whether or not you try again.
What does an ignition interlock device do?
An ignition interlock is a breath-alcohol tester wired into your car ignition. You blow into it before starting the engine; if your breath alcohol is above the state threshold, the engine will not start.
While you are driving, the device asks for rolling retests at random intervals. Every sample, skipped test, and lockout is recorded and sent to the agency monitoring your case.
