3 Things to Know About Ignition Interlock Devices in Wisconsin

Like other states, Wisconsin has increased drunk driving penalties in recent years to include ignition interlock devices, or IIDs. These devices prevent you from driving if they detect alcohol on your breath.

At Kim & LaVoy, S.C., we understand the impact IID orders and other OWI penalties can have on a person, and we fight to give our clients the best OWI defense. Below are three important things to know about drunk driving charges and ignition interlock devices in Wisconsin. 

1. Ignition interlock devices are required in many but not all OWI convictions.

  • If you are arrested for a first-time offense and your BAC is 0.15 or higher, or if you are charged with a subsequent OWI offense, then a conviction would mean that you have to install an ignition interlock in your vehicle. Refusing a breath, blood or urine test could also result in an IID order.

2. An IID order applies to each of the vehicles you own or drive.

  • This is particularly noteworthy when you consider the cost of installation. An ignition interlock requirement can mean a significant increase in the cost of a DUI conviction, though the court has discretion to exempt one or more of your vehicles if installing IIDs in them would cause undue financial hardship to you.

3. An IID order usually goes into effect when your regular driver’s license is reinstated, unless you apply for an occupational license.

  • All drunk driving convictions in Wisconsin result in a mandatory period of license suspension or revocation. Depending on the circumstances, you may be eligible for an occupational license that lets you drive to and from work or school. You may also be required to keep an IID installed in the vehicle while you use your occupational license.
