Alcohol Ignition Interlock Programmes for Reducing Drink Driving Recidivism

This article describes a review of the use of alcohol ignition interlock programs for reducing drink driving recidivism. To operate a vehicle equipped with an ignition interlock device, the driver must first provide a breath specimen. If the breath alcohol concentration of the specimen exceeds the predetermined level, the vehicle will not start. As a measure to reduce circumvention of the device (i.e., someone else blows into the mouthpiece), random retests are required while the vehicle is running. The review was based on the Cochrane Controlled Trials Register, as well as relevant electronic databases and the Internet. One randomized controlled trial (RCT) and ten controlled trials were identified, as well as three ongoing trials. The RCT showed that the interlock program was effective while the device was installed in the vehicle. Controlled trials support this conclusion, with a general trend in both first-time and repeat offenders, towards lower recidivism rates when the interlock device is installed. Neither the RCT nor the controlled trials provide evidence for any effectiveness of the program continuing after the device has been removed. The authors conclude by calling for studies that address ways of improving recidivism rates in the long term, as the major challenges are participation rates, compliance, and durability.
