"We have calculated that 41 percent of drivers with an ignition interlock requirement have installed an ignition interlock device," JLARC staff member Aaron Cavan said during the committee presentation. JLARC staff told the committee their dataset covered about 66,000 device restrictions from January 2018 through June 2025 and used an ~8,000-person sample matched to employment-security income records for subgroup analysis.
The report found that half of drivers with IID requirements earn less than $28,000 per year and that installation rates ranged from about 30% for drivers earning $0–$10,000 to about 74% for those earning more than $100,000. "The installation rate increases with driver income," Cavan said.
