CA – Senate Bill 1046

As of January 1st, 2019 till December 31st, 2025, Senate Bill 1046 has instituted a pilot program that mandates the use of ignition interlock devices for all individuals convicted of DUI or DWI while under the influence of alcohol or a combination of alcohol and drugs.

The duration of an ignition interlock program is contingent on the number of DUI convictions a driver incurs, with the following guidelines:

  • First-time offenders: Required to participate for 6 months to 1 year.
  • Second-time offense: Mandatory participation of at least 1 year.
  • Third-time offense: Obligatory commitment of at least 2 years.
  • Fourth-time offense or more: A minimum requirement of 3 years.

*The duration of an ignition interlock program can differ based on the circumstances, particularly if the DUI case resulted in injury or included additional criminal charges.
