When Will I Need an Ignition Interlock in Wisconsin?

Are you wondering if you need an Ignition Interlock after an OWI (or Operating While Intoxicated) arrest or conviction in Wisconsin? Currently, Wisconsin requires Ignition Interlock Devices for OWI first-time cases with a BAC of .15 or greater, or repeat cases. In addition, any drivers who refuse to provide a breath or blood sample for a chemical test at a traffic stop will need an Ignition Interlock.

Ignition Interlock Law in Wisconsin

If you are ordered to use an Ignition Interlock in Wisconsin, the device must be installed in every vehicle you own. During your restricted driving privileges period, you can only operate an Ignition Interlock-equipped vehicle.

In most cases, you will be advised to install your Ignition Interlock at the point before your case is adjudicated, or post-conviction.

Applying for an Occupational License in Wisconsin

In some OWI cases, you can choose to apply for an Occupational License from the Department of Motor Vehicles (DMV).  You must have an Ignition Interlock installed in every vehicle registered or titled under your name (unless the court exempts).

This license will allow you to drive to and from work, school, or to take care of essential household activities with an Ignition Interlock equipped in the vehicle you operate. Before you can have an Occupational License, however, you must serve a mandatory license revocation or suspension period. Below are the different cases based on offense and/or charge regarding when you can apply for the Occupational License.

• First – immediately eligible
• Second and subsequent – You must wait 45 days before becoming eligible to apply
• Causing injury while intoxicated – 60 days before becoming eligible
• Causing great bodily harm – 120 days
• Negligent homicide while intoxicated – 120 days
• First and refused test – 30 days
• Second and refused test – 90 days
• Third and refused test – 120 days
