IID and DUI in California
Ignition Interlock Device: A Smarter Way to Combat DUI in California
By Los Angeles DUI Defense Attorney
Over the past 30 years, drunk driving has caused more than 1 million injuries and over 50,000 fatal accidents in the United States. These statistics are often cited by Mothers Against Drunk Driving (MADD), a leading nonprofit organization advocating for stronger DUI enforcement nationwide. In California, MADD has played a major role in pushing for tougher DUI laws, pointing to the consistent rise in DUI-related crashes each year.
But there is a more effective alternative to harsh criminal prosecution: the Ignition Interlock Device (IID). Initially adopted in numerous countries and throughout California, IID technology is helping prevent DUI incidents while allowing drivers accused of DUI in Los Angeles to continue to drive and maintain their daily lives. As a Los Angeles DUI Defense Attorney, I’ve seen firsthand how these devices can be a fair and proactive solution for those facing DUI charges.
What Is an Ignition Interlock Device?
An IID is a breathalyzer installed directly into a car, requiring the driver to blow into the device before the engine starts. If the driver has alcohol in their system, the vehicle will not start. This technology helps prevent impaired driving and allows individuals to keep working, caring for their families, and fulfilling other responsibilities.
How the IID Law Began in California
The ignition interlock pilot program initially began in four California counties: Los Angeles, Alameda, Tulare, and Sacramento. Under this program, DUI offenders were required to install IIDs for:
- 6 months after a first DUI conviction
- Up to 3 years for repeat DUI convictions without injury
- Up to 4 years for DUI convictions involving injury
The program covered over 13 million people and provided the framework for a statewide expansion based on its success. Following the initial legislation, California began to require an IID for all subsequent DUI convictions. Presently, a first offender DUI can opt out of the IID requirement.
New 2025 Legislation: IID for First-Time Offenders
In early 2025, the California State Assembly passed a bill that would require all DUI offenders, including first-time offenders, to install an IID in their vehicles. Under current law, a first DUI conviction in California does not mandate an IID. This proposed law would change that by eliminating the exception for first-time offenses.
However, this legislation is not yet law—it still needs to be approved by the California Senate and signed by the Governor. If enacted, it would mark a significant shift in DUI policy statewide. Supporters argue that it would save lives and prevent repeat offenses from the outset. As a Los Angeles DUI Defense Attorney, I closely monitor legislation like this because it directly impacts my clients and how we build their defense.
Why the IID Program Expanded Statewide
In the past, such supporters as Senator Jerry Hill, with strong backing from MADD, the National Transportation Safety Board (NTSB), and the Centers for Disease Control and Prevention (CDC), introduced legislation to expand IID requirements throughout California.
Supporters of IID argued that tools like sobriety checkpoints are reactive, while ignition interlocks are preventative. His legislation was designed to help DUI offenders resume lawful driving sooner, reduce court fines, and most importantly, prevent future DUIs. MADD reports that more than 1.77 million drunk driving attempts have been stopped nationwide by IIDs, including over 124,000 incidents in California alone.
Benefits of IID Implementation
- Avoids full driver’s license suspension so individuals can keep working
- Helps prevent repeat DUI offenses
- Qualifies California for federal highway safety funding (e.g., California received $$$ millions)
- Encourages compliance while offering a second chance to DUI drivers
Opposition from the DMV and Limitations
Despite its benefits, the California DMV opposed mandatory IID use, arguing that it relies too heavily on voluntary compliance and doesn’t address habitual offenders. Additionally, IID laws do not apply to drug-related DUIs, which require full license suspensions without the option of a restricted license.
Industry Support and Market Growth
The IID legislation has received strong support from industry leaders like Intoxalock, which developed its technology with Iowa State University and currently operates in 41 states. The IID market has tripled in size over the past 10 years and is expected to continue growing as more states adopt ignition interlock laws. Other manufacturers also make IID devices for all kinds of cars (not motorcycles).
