1. Alcohol Interlocks in prevention and the enforcement of drink driving law Safe and Sober Edinburgh July Richard Allsop University College London

2. The alcohol interlock
... is long-established in North America and now in use or being trialled in many European countries including the UK e g for:
mandatory use by convicted offenders
voluntary use in commercial transport
mandatory use in professional driving with vulnerable passengers
A device fitted to the vehicle whereby no-one can drive without passing a breath-test using a hand-held tube and repeating this within 10 minutes of receiving random prompts to do so while driving.
The first use is an additional tool in the punishment and rehabilitation of offenders
The last two uses are preventive – the first accepted as a sign of social responsibility by fleet operators, the second as a requirement for, say, school bus drivers.

3. Alcohol interlocks used with the mix of offenders
Requirement to use an alcohol interlock for a time is an additional form of punishment in itself
But it also provides flexibility in the use of other punishments – allowing more consideration of the situation of each offender – e g effect of disqualification differs among those offending similarly

4. Alcohol interlocks used with the mix of offenders
Requirement to use an alcohol interlock is more preventive of drink driving than disqualification
But used by itself the preventive effect does not persist when the user is free to drive without the interlock
So its use can well be accompanied by a rehabilitation course

Since 2008, ETSC has been monitoring the spread of use of interlocks by means of the Alcolock Barometer – a series of maps in which countries where no use of interlocks has yet been provided for are coloured blue. Other colours indicate different stages in trialling their use.

15. ... so it’s not plain sailing
Many possibilities for interlocks are being explored but issues are arising:
– motivation of the judiciary
– cost of the interlocks and who pays
– procedure for and costs of using log data from interlocks to support users and to inform policy
– public perception of users
These issues are spread over a number of countries, differing among countries

16. Where to go from here?
Progress use of alcohol interlocks and rehabilitation courses with offenders to achieve more tailored penalties and reduce reoffending
Encourage use of alcohol interlocks for prevention
Harmonise alcohol interlock technology, require fittability and improve convenience of use
Thanks to the ETSC office team, especially Francesca Podda for their help in preparing this presentation
