What Minnesota requires
Minnesota runs the interlock as a program you enroll in, not just a device you fit. It is the route back to driving during a revocation, and it is mandatory for repeat offenses. The device is defined by statute as one that blocks the ignition at 0.02% or above.
- First offense: Optional for a first offense; mandatory on a second or later alcohol or drug offense within 20 years (10 years for incidents before 1 July 2025). Drivers canceled as inimical to public safety serve 3–6 years
- Lockout threshold: 0.02% — the statute defines the device as one that blocks the ignition at that reading or above
- Program run by: Minnesota Department of Public Safety, Driver and Vehicle Services
Why Minnesota 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. Fillmore County runs at or below the Minnesota 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 Preston
Where can I get an ignition interlock device installed in Preston, MN?
We index 2 certified installation points in Preston, run by Intoxalock, RoadGuard Interlock. 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 Minnesota?
Minnesota 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 Preston 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 Minnesota?
Almost certainly not. 0.02% — the statute defines the device as one that blocks the ignition at that reading or above 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.
