New report: Getting interlock schemes right

Alcohol ignition interlock schemes (AIIS) are a strategy that is used by many jurisdictions to address drink driving. The Centre for Automotive Safety Research (CASR), part of the University of Adelaide, has just released a new report which evaluates how effective AIIS are, as well as recommending a number of characteristics that can promote best practice.

Outcome evaluations of AIIS indicate that while they are successful in reducing or eliminating drink driving behaviour, once it is removed the risk of re-offending is not reduced. A sample of factors outlined within the paper that contribute to AIIS effectiveness include:

  • Compliance with agreed standards
  • Increased participation in AIIS which can in turn reduce recidivism
  • Timeliness – engaging offenders in the scheme as soon as possible after conviction
  • Minimising user costs and complexity in participation (e.g. ensuring equity of access for rural or remote participants)
  • Keeping participants informed of all violations the device records
  • Integration of treatment, monitoring, counselling and other support with the AIIS
  • Adequate police enforcement of drink driving laws
