Question: What Is an Ignition Interlock Device in Wisconsin?
Answer: An ignition interlock device is a device put on a person's vehicle upon conviction of OWI first offense and higher. For first offenses it's if you had a BAC, or blood alcohol level, of .15 or higher or there was refusal involved. And this is a device to determine whether or not you have been drinking before you actually drive the car. These are very unpleasant for people to have in their cars as you have to blow into it when you pick up your kids from school; you have to blow into it if you have a date. It is the kind of thing that is not secretive. Everybody knows if you have an ignition interlock device in your car.
