California DMV mandates ignition interlock device installation for convicted drivers by 2026

California Assembly Bill 366, introduced on February 3, 2025, aims to enhance road safety by mandating the installation of certified ignition interlock devices for individuals convicted of specific driving offenses. Set to take effect on January 1, 2026, the bill seeks to address the alarming rates of repeat offenses among convicted drivers, particularly those involved in DUI incidents.

The bill outlines a clear protocol for the Department of Motor Vehicles (DMV) to follow upon receiving a court's abstract of conviction. Convicted individuals will be required to install an ignition interlock device on every vehicle they operate, with strict timelines for installation and maintenance. They must also provide proof of installation to the DMV and pay an administrative fee. Notably, the bill emphasizes that having an ignition interlock device does not grant the individual the right to drive without a valid license.

Key provisions include mandatory servicing of the device every 60 days and a DMV monitoring system to ensure compliance. If a person cannot meet the installation requirements—such as not owning or having access to a vehicle—they must certify their circumstances to the DMV.

The bill has sparked discussions among lawmakers and advocacy groups. Supporters argue that it will significantly reduce the likelihood of repeat offenses and improve public safety. However, some opponents raise concerns about the financial burden on low-income individuals who may struggle to afford the installation and maintenance costs of these devices.

Experts suggest that the economic implications could be substantial, as reduced repeat offenses may lead to lower insurance premiums and fewer accidents, ultimately benefiting taxpayers. As the bill progresses through the legislative process, its potential to reshape California's approach to driving offenses remains a focal point of debate.

With its implementation on the horizon, AB 366 could mark a pivotal shift in how the state addresses impaired driving, aiming to create safer roads for all Californians.
