What Is the Ignition Interlock Device?
The Ignition Interlock Device (IID) is installed on the dash of DUI offenders' vehicles. It is a penalty for driving under the influence in California. Usually, IIDs are installed as a penalty for multiple DUI offenders and as a consequence for other serious DUI penalties, but judges can sometimes require the IID for first time DUI offenders.
The IID has gained recent popularity as a penalty for drunk drivers—as it both punishes and serves as a deterrent against future offenses. It works similar to a breath test in that it tests a breath sample for the amount of alcohol. Once installed, you will have to provide a clean sample any time you wish to start the vehicle and at rolling intervals. This is an expensive machine and must be calibrated on a regular basis—fees that will fall on your shoulders.
The IID can also be a form of alternative sentencing. Your lawyer may be able to negotiate IID installation in lieu of a jail sentence. Learn more about ignition interlock devices.
