When Will I Need an Ignition Interlock Device in Iowa?

Smart Start Ignition Interlock Device (IID) the SSI-20/30

Iowa requires Ignition Interlock Devices for some individuals who are convicted of Operating While Intoxicated, or OWI.

When your license is revoked from the Department of Transportation (DOT) because of your OWI, you may be eligible for a temporary restricted license. This restricted license is only valid if you install an Ignition Interlock Device into your vehicle.

What’s an Ignition Interlock Device?

An Ignition Interlock is a small device that must be installed in your vehicle after an OWI conviction. When the user blows into the device, their breath alcohol concentration (BrAC) level is detected. Any BrAC level at or above the set fail limits for the device, usually at .025, will cause the vehicle to not start. In other words, your BrAC level needs to be below .025 to start your vehicle.
