Should California require all first-time DUI offenders to install ignition interlock devices in their vehicles?
In September 2026, the California legislature failed to pass AB 1830, a bill that would have mandated ignition interlock devices for first-time DUI offenders. The Assembly had previously passed the bill in a 74-0 vote before the Senate Appropriations Committee amended it to make the devices optional.
Why it matters
Public defenders argued that mandatory interlocks place a disproportionate financial burden on low-income individuals and may discourage offenders from reinstating their licenses. Advocates now intend to renew their push for universal interlock mandates in the upcoming legislative session.
Current California law permits judges the discretion to require ignition interlock devices, which use breathalyzers to enable vehicle ignition, for first-time offenders. Recent legislation now allows prosecutors to charge a third DUI within 10 years as a felony.
The players
Gavin Newsom
He is the current Governor of California who signed four new DUI-related bills into law in September 2026.
Sabrina Cervantes
She is a State Senator representing Riverside who was cited by Sacramento police for a suspected DUI in 2025.
Kellie Montalvo
A resident of Corona who lost her son in a 2020 car crash.
Clarissa Cervantes
An individual who received her second DUI in 2023.
The details
The Senate Appropriations Committee amended the bill to allow first-time offenders without injury-related incidents to choose license suspension over the interlock device. Meanwhile, new laws signed in September 2026 also add DMV violation points for vehicular manslaughter convictions and increase license revocation periods for repeat offenders.

Legal Context
The failure of AB 1830 marks a legislative departure from trends in other states that have adopted universal ignition interlock mandates. This outcome maintains the existing status quo where judges retain discretion regarding sentencing requirements for first-time offenders.
First-time DUI offenders in California will continue to face judicial discretion rather than a mandatory interlock requirement. Residents should be aware that new state laws now elevate third-offense DUI charges within 10 years to felony status.
The takeaway
While the effort to mandate interlock devices stalled, the state has tightened penalties for repeat offenders and vehicular manslaughter. Drivers should remain informed of these evolving statutes as policymakers continue to debate the balance between rehabilitation and public safety.
