Ignition Interlock Devices — What You Need to Know

Initially authorized for use in California in 1986, ignition interlock devices are intended to deter and prevent drunk driving among individuals convicted of driving under the influence (DUI).  But what are they?

Slightly larger than cell phones, ignition interlock devices (IIDs) are connected to dashboard wiring and located conveniently to the car driver.  The California Vehicle Code currently gives courts discretion to order use of the devices for first-time DUI offenders and mandates installation of IIDs for other DUI offenders.

Our attorneys skillfully defend drivers accused of DUI and are well versed in the practicalities of IIDs, including the following:

• IIDs require and record breath samples for vehicle ignition.  Somewhat like a breathalyzer, IIDs require random samples through a mouthpiece during a drive.  The user picks up and blows into the device.
• Providing a breath sample into an IID that indicates alcohol on the breath can result in fines and jail time.
• IID devices are designed to detect attempts to circumvent the device.
• IIDs are installed and must be maintained every 60 days at the expense of the driver.  The device will record with a backup battery if the car battery fails.

Initiated in July 2010, a pilot program mandates installation of ignition interlock devices for first time DUI offenders in Alameda, Los Angeles, Sacramento, and Tulare counties.  Results of this program may dictate increased use of IIDs throughout California.  Time — and the interlock devices themselves — will tell. But these devices are not always accurate and a skilled DUI defense attorney can help when you face legal issues because of an IID. Contact us today for legal support and guidance.
