Iowa Ignition Interlock Requirements
Iowa allows drivers who have their license suspended due to OWI (Operating While Intoxicated) to regain driving privileges if they install a state-approved ignition interlock device (IID) to monitor their breath alcohol concentration (BrAC). This guide will explain the steps drivers must take if convicted of an OWI.
The Iowa Ignition Interlock Program
In Iowa, operating a vehicle while intoxicated is known as OWI, and applies to anyone who is driving with a breathe alcohol concentration (BrAC) of .08 percent or higher, or who has any amount of a controlled substance in their blood.
Drivers who are charged with OWI in Iowa will have their license revoked, including first-time offenders. The period of revocation is determined by the court, but all offenders will have their license revoked if convicted. Iowa allows convicted drivers to apply for a temporary restricted license if being unable to drive is a hardship, but drivers must install a certified ignition interlock device on all vehicles they operate to qualify.

Compliance-Based Removal Program
Under the Compliance-Based Removal (CBR) program, non-compliance with IID requirements can extend the IID requirement period by 60 days per violation. Violations include:
- 10 or more failed BrAC tests (≥ 0.04%) within 30 days
- 5 or more failed BrAC tests (≥ 0.04%) within 24 hours
- Tampering with or attempting to circumvent the IID
- Removing the IID without authorization
How Can I Get a Temporary Restricted License in Iowa?
For some people, going without a driver’s license is a hardship. They may have no other way to get to work or school. In those cases, they may be eligible for a restricted license that would allow them to drive to approved locations like work, school, home, treatment, and medical appointments. You may be eligible for a temporary restricted license if you meet the following criteria:
- Pass any required exams
- Provide a certificate of proof that an ignition interlock device has been installed
- Submit proof of SR-22 insurance
- Pay any required fines
- Fill out the temporary restricted license request form
Medical Waivers
Drivers who have a verifiable medical condition preventing the proper use of an IID can apply for a medical waiver. If granted:
- IID installation is not required to receive a TRL
- The TRL will limit driving to specific locations, such as work, school, or medical appointments.
Effective Date: These changes take effect on January 1, 2025, and apply to offenses that occur on or after this date.

An ignition interlock device is a breathalyzer that is installed in your vehicle to prevent drinking and driving.
