Abstract
An alcohol interlock device is a breathalyser that is connected to the ignition of a car. To start the car, participants must provide an alcohol-free breath sample. During the trip, breath test updates will be requested, and details including distances and violations are recorded for monthly evaluation. The purpose of the device is to prevent individuals from driving under the influence of alcohol – a universal issue that impacts public safety. Alcohol interlock programmes have the potential to be effective while the device is fitted; however, success rates in reducing driving under the influence of alcohol are limited by factors such as low participation rates, and ineffectual long-term behavioural change. This article presents (1) a brief description of the research on alcohol interlock programmes, (2) barriers to low installation rates, (3) the impact interlocks have on daily life, and (4) showcase the approach that the Department of Corrections New Zealand is taking to maximise interlock effectiveness.
