Ignition interlock devices.

Assembly Members Petrie-Norris and Ransom propose comprehensive changes to California's ignition interlock device (IID) requirements for driving under the influence offenses, making installation mandatory for first-time offenders and establishing an income-based fee structure to ensure broader accessibility.

The legislation removes judicial discretion over IID installation for first-time DUI convictions and extends existing IID provisions indefinitely beyond their current January 2026 sunset date. Under the new requirements, courts must order IID installation upon initial conviction, with installation periods ranging from six months for first offenses to 36 months for those with multiple prior convictions.

The bill creates a sliding fee scale based on federal poverty levels, with individuals at 125% or below of the poverty line paying 10% of IID costs and those between 126-425% paying incrementally higher portions. IID providers must absorb remaining costs not covered by offenders. Program costs now explicitly include administration, installation, maintenance, and device recalibration. The Department of Motor Vehicles must expand its annual legislative reports to track outcomes, including crash data and subsequent violations among first-time offenders required to install IIDs.

The measure maintains existing enforcement mechanisms, requiring IID servicing every 60 days and immediate license suspension for tampering attempts or maintenance failures. Commercial drivers operating non-commercial vehicles and individuals with documented medical conditions preventing device use remain exempt from IID requirements. The legislation specifies that no state reimbursement is required for local agencies or school districts to implement these changes.
