Official Summary Text

AB 366, Petrie-Norris.
Ignition interlock devices.
Existing law, commencing January 1, 2019, made various changes to the law governing ignition interlock devices (IID), including, among other things, requiring a person who has been convicted of driving a motor vehicle under the influence of an alcoholic beverage, as specified, to install for a specified period of time as ordered by the court, an IID on the vehicle they operate, provided however that installation of an IID is discretionary for a first offender, as specified; authorizing a person convicted of driving a motor vehicle under the influence, if all other requirements are satisfied, including the installation of an IID, to apply for a restricted driver’s license without completing a period of license suspension or revocation; and requiring ignition interlock device manufacturers to be in compliance
with specified provisions relating to payment for the costs of an ignition interlock device. Existing law makes these changes operative until January 1, 2026. On January 1, 2026, existing law, as it relates to these provisions, is generally reinstated to read as it read prior to January 1, 2019. Existing law makes it a crime to violate certain provisions relating to IIDs and motor vehicles equipped with IIDs.
This bill would extend the operation of these provisions until January 1, 2033, and would instead reinstate the law to how it read prior to January 1, 2019, on January 1, 2033. By extending the application of a crime, the bill would impose a state-mandated local program.
The California Constitution requires the state to reimburse local agencies and school districts for certain costs mandated by the state. Statutory provisions establish procedures for making that reimbursement.
This bill would provide that no reimbursement is required by this act for a specified reason.
