Compiled from providers’ own public location directories and deduplicated to unique physical places (how we build this index). Listing is not an endorsement, and no center pays to appear.

What Iowa requires
Iowa revokes your driving privileges after an OWI whether or not the court convicts you. The way back is a temporary restricted license, and on a first offense you need a device on every vehicle you drive to get one. A medical waiver exists for offenses from 1 January 2025, verified by a doctor.
- First offense: For the length of the temporary restricted license on a first OWI; with two or more offenses, at least 365 days from the date you receive the license or the length of it, whichever ends later
- Lockout threshold: Set by the preset limit in the device; providers are approved by the Division of Criminal Investigation
- Program run by: Iowa DOT, Motor Vehicle Division
Why Iowa 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. Cass County runs above the Iowa average, which is part of why the interlock requirement here is enforced the way it is. 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 Griswold
Where can I get an ignition interlock device installed in Griswold, IA?
We index 1 certified installation point in Griswold, 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 Iowa?
Iowa 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 Griswold 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 Iowa?
Almost certainly not. Iowa does not print one fixed number in the statute — the level is set by the certifying agency in the device standard, typically between 0.02% and 0.025% BAC, far below the 0.08% driving limit. 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.
