Ignition Interlock Device (IID)
An Ignition Interlock Device (IID) is a device that is wired to your car’s ignition that requires a breath sample prior to starting the ignition. If the IID detects alcohol on your breath, the engine will not start. Additionally, the device requires periodic samples as you drive to be sure that the driver’s breath sample doesn’t exceed a certain limit. The IID will cost about $70/month for monitoring.
As of January 1, 2012, if you enter Diversion, Oregon state law requires that you install an IID in any vehicle that you operate during the one year period in which you have driving privileges. The IID must be installed by a state authorized installer.
In addition, if you are convicted of a DUII in Oregon, you must install an IID during any hardship permit period as well as for a minimum of one to two years after the end of your court supervision period.
Here is a list of state-approved IID installers.
