When does a DUI conviction lead to IID installation?

After a drunk driving conviction, the penalties of a conviction can limit a person’s freedom in various ways. Many people face limitations like jail time. They may also lose their license, but in some cases they may still be able to drive with an ignition interlock device (IID). What should California drivers know about these devices and their use after a conviction for driving under the influence (DUI)?

What is an Ignition Interlock Device?

An IID is a device that tests your blood alcohol content (BAC) with a breath test before you start your vehicle and randomly as you drive. Judges may order people to install these devices due to a drunk driving conviction, refusal to submit to BAC testing or other alcohol-related offenses. IID use involves regular maintenance and some additional costs depending on a person’s ability to pay.

The law does not require IID installation for every DUI case. However, convictions with prior DUI charges on your record or for DUI charges that caused injury will involve mandatory IID installation for you to drive. Depending on the details of the case, the court may order IID use for up to three years under California Vehicle Code 23575.

Will I have to install an IID in my car?

While use of an IID can provide people with the opportunity to drive after a conviction, it may not be a requirement in every case. It is often important to discuss your case with an attorney early in the legal process to determine how a DUI could impact your life, including whether future driving privileges depend on IID installation. An experienced lawyer can examine the details of your case and build a personalized defense to protect your freedom.
