Ignition Interlock Devices

What is an Ignition Interlock Device

Ignition Interlock Devices (IID) are machines somewhat like a breathalyzer to detect traces of alcohol on a person's breath. These machines require that an individual produce a breath sample devoid of alcohol prior to starting the vehicle and at random times after a vehicle has started. The IID will prevent the vehicle from starting or stop the engine from operating if it detects alcohol on a driver's breath.

When is a Person Required to Obtain an IID

In Wisconsin courts are required to order the installation of an IID whenever a person is found guilty of improperly refusing to take a blood or breath test, for any second and subsequent conviction for an OWI offense, OWI 1st offenders with a blood alcohol level of .15 or more, and OWI 1st offenders who were involved in an accident causing injury. A sentencing court ordering the installation of an IID will require that all vehicles registered to or operated by the defendant be equipped with one of the machines.
