CA SB1021

Authorizes courts to offer pretrial diversion for first-time DUI offenders with no prior DUI convictions and who have not completed diversion in the past 10 years, contingent on successful completion of court-ordered terms.

Requires diversion participants to install an ignition interlock device for at least 12 months and complete education and counseling programs (3 months/30 hours for those under 0.2% BAC or 9 months/60 hours for those at 0.2% BAC or higher).

Establishes recordkeeping requirements for ignition interlock device manufacturers, including maintaining participant files for at least 3 years with installation, service, calibration, and removal information.

Implements a tiered fee schedule based on income for ignition interlock device costs, ranging from 10% for those at 100% of federal poverty level to 100% for higher-income offenders, with manufacturers responsible for the unpaid portion.

Extends the required ignition interlock device installation period by 60 days if a driver attempts to start the vehicle with a breath alcohol concentration exceeding 0.03% within the final 60 days of the mandatory term.
