This paper reports on the progress of the first court-ordered trial of alcohol ignition interlocks in Queensland. It focuses on the predominant factors affecting the implementation of the program and the current self-reported impact of using interlocks on key program outcomes such as drinking and drink driving behaviours. The report highlights issues influencing participation rates, the relationship between the downloaded and self-reported data and provides suggestions for future interlock programs.
