Ignition Interlock Device | OWI in Wisconsin

Fast Facts About Ignition Interlock Devices in Wisconsin

OWI convictions are costly. If convicted, you will pay fines and face penalties. One of the penalties is to install an ignition interlock device (IID) on every vehicle owned by or registered to you.

In this post, we cover four common questions about IIDs in Wisconsin.

4 Questions About IIDs in Wisconsin, Answered

  • 1: What Is an Ignition Interlock Device? An ignition interlock device measures your breath-alcohol concentration and locks the vehicle’s starting mechanism if the concentration is too high. IIDs are required as a condition that allows you to keep your license after an OWI conviction. The IID effectively operates as a “breathalyzer” for the vehicle.
  • 2: When is an IID Required? IIDs are required to be installed for a minimum of one full year from the time of conviction and/or reinstatement of driving privileges. Wisconsin judges order the installation of ignition interlock devices for:
  • ALL repeat offenders.
  • ALL first-time offenders with a BAC of 0.15 percent or higher.
  • ALL drivers who refuse to provide a breath or blood sample for a chemical test at a traffic stop.
  • 3: How Much Does it Cost to Install an Ignition Interlock Device? It is up to you to bear the cost of installing the devices on your vehicles. Prices vary by model and are influenced by the make and model of the vehicle they are installed in. Average installation costs in Wisconsin are $100. However, the devices have monthly fees and require bi-monthly calibration, both of which are added expenses. In general, it costs approximately $1,000 to maintain the IID for a year in one vehicle. When it comes time to remove the device, there is an additional charge associated with that. The state does offer assistance for people experiencing financial hardship.
  • 4: Where Do I Get an IID? You will need to find an IID service center to obtain the device. Ignition interlock devices are leased from the service center provider. The lease agreement typically includes installation, monthly service, and removal costs. Any additional costs such as calibration or resetting the device after a violation are assessed separately.
