Iowa OWI (operating while intoxicated)

Iowa's ignition interlock devices

Iowa law provides for certain individuals who have had their driver's license revoked for an OWI (i.e., operating while intoxicated or drugged) to be eligible for a temporary restricted license if an ignition interlock device is installed on all vehicles. An ignition interlock device is designed to prevent an individual from operating a motor vehicle while under the influence of alcohol.  Connected directly to the electrical system of a motor vehicle, it prevents the vehicle from starting when the alcohol level of the driver's breath is above a preset limit.

The following is a list of ignition interlock devices that have been approved by the Division of Criminal Investigation (DCI) for use in the State of Iowa:

Intoxalock 877-777-5020
Lifesafer (FC-100) 800-369-3661
