  1. Alcohol Ignition Interlockprogram in The Netherlands The alcolock combined with a counselingsupport program Rob van Beekum, Driver Rehabilitation Department/Dutch Driving Test Organisation CBR Jan Vissers, DHV Environment and Transportation

  2. Overview • Status DUI measures in NL • Legal framework AII-program • Intended setup AII-program • Intended contents of support program • Possible reduction of casualties • Small scale experiment

  3. DUI-measures in NL: presentsituation • Educational Measure Alcohol and traffic (EMA)- rehabilitation program- BAC 1.3 – 1.8 per mille • Medical-psychiatric assessment- BAC 1.8 per mille and higher

  4. DUI-measures in NL: futuresituation • EMA - ‘light’- BAC 0.8 – 1.0 per mille • EMA - ‘standard’- BAC 1.0 – 1.3 per mille • Alcohol Ignition Interlock program- BAC 1.3 – 2.1 per mille • Medical - psychiatric assessment- BAC 2.1 per mille and higher

  5. Legal framework AII-program • Administrative law • Assumption: licence holder no longer meets required standards of driving • When BAC between 1.3 and 2.1 per mille: obligation to engage in AII-program • No participation or no completion: driving license invalidated for 5 years

  6. Setup of the Dutch AII-program • All DUI offenders between 1.3 and 2.1 per mille • Duration: two years • Tailor-made support program for each participant • High participation rate and low failure rate • Costs of AII-device to be paid for by participants • Costs of support program to paid for by health insurance?

  7. Principles of the support program • AII-device will be combined with a support program to improve efficiency of the measure (Marques et al, 2000 and 2004) • Support program will motivate participants to change their DUI behaviour and work on their alcohol dependency • Participants with ‘bad’ output will need more intensive support than participants with ‘good’ output: tailor-made support

  8. Contents of the support program • Introductory phase:- several group sessions (introduction to AII-device, elements of EMA-program)- individual assessment interview • Standard support program:- no severe drinking problems- ‘good’ output from AII-device: standard program will be continued- ‘bad’/ ‘problematic’ output: motivation to participate in more intensive support program • Intensive support program- severe drinking problems/ alcohol dependency- intensive, more therapeutic support needed

  9. Standard Intensive Support program Introduction

  10. Reduction of DUI casualties • Estimated reduction (SWOV, 2007): about 30 DUI casualties on a total of about 800 traffic casualties:- 25% of all casualties caused by drink driving- about 75% (153) of these are due to BAC levels of 1.3 or more- group of drivers with these BAC levels: about 80,000- each year 13,000 DUI drivers with these levels apprehended- 75% (about 10,000 people) will participate in AII-program - when AII-program lasts two years: after a two year period 20,000 heavy drinkers will drive with an alcolock- relapse rate is estimated to be reduced with 80%- reduction will be: 153 * 0.25 * 0.80 = 31

  11. Cost-benefit analysis • Costs of one traffic casualty in NL has been calculated to amount to about 11 million Euro • By saving 30 casualties, each year about 300 million Euro can be saved • The AII-program is estimated to cost about 30 million Euro each year • This means cost-effectiveness of AII-program is very high

  12. Small scale experiment (1) • Planned for 2008 • Recruitment of participants: EMA - course group • Two regions in The Netherlands (urban - rural) • Two alcolock ‘providers’: Dräger and ACS • Each region: 25 - 50 participants • Duration of experiment: 3 - 5 months

  13. Small scale experiment (2) • Emphasis on process evaluation:- effectiveness of procedures (installation, collection and analysis of alcolock data, effectiveness of Dutch standard setting, etc.)- communication between organisations- use of data output in support program- effectiveness of individual assessment interview- effectiveness of elements of introductory program- acceptation and satisfaction ratings of participants- psychological, social and behavioural impact on participants
