Toward a performance-based approach to the Queensland alcohol ignition interlock program: the impact of performance record on risk of recidivism

Drink driving is a significant contributing factor to road trauma. The Queensland Alcohol Ignition Interlock Program (AIIP) aims to reduce drink driving recidivism among problematic offenders and has been evaluated to measure its effectiveness. Results of this evaluation revealed a significant reduction in drink driving recidivism associated with interlock fitment, but an increased risk from 55 days after removal, compared with those still suspended from driving. In addition, poor interlock use performance data was found to be predictive of a greater risk of future reoffending. These findings will inform future policy development to optimise the effectiveness of the AIIP in Queensland.
