Samenvatting Im Rahmen eines europaeischen Feldversuchs wurden Alcolocks in Fahrzeuge - Lkw und Busse - von Berufskraftfahrern in Spanien, Norwegen und Deutschland sowie in Autos von zwei Gruppen nichtprofessioneller Fahrer - Trunkenheitsfahrer und Alkoholabhaengige - in Belgien fuer eine Periode von einem Jahr installiert. Zur Durchfuehrung einer qualitativen Analyse der Erfahrungen mit den Alcolocks wurden die Fahrer vor, waehrend und nach dem Versuch befragt. Machbarkeit und Praktikabilitaet der Einfuehrung von Alcolocks in Europa wurden bewertet. Aus den Befragungen und den aufgezeichneten Alcolock-Daten geht hervor, dass Alcolocks in professionellen und nichtprofessionellen Bereichen praktikabel sind. Die Benutzung wurde als leicht eingeschaetzt. Die Akzeptanz war gut und blieb waehrend der ganzen Periode hoch. Die Berufskraftfahrer wiesen wenig positive Atemalkoholtests auf, waehrend bei der Haelfte der Trunkenheitsfahrer zehn und mehr solche verzeichnet wurden. Zur Gesamtaufnahme siehe ITRD D361720. (KfV/A) ABSTRACT IN ENGLISH: Within the framework of a European qualitative field trial on alcohol ignition interlocks, alcolocks were installed in the vehicles of three groups of professional drivers (30 Spanish and 30 Norwegian bus drivers and 34 German truck drivers) and in the vehicles of two groups of non-professional drivers (33 Belgian drink driving offenders and 7 Belgian alcohol dependent patients) for a period of one year. To perform a qualitative analysis of the experiences of the alcolock users and their social environment, they were interviewed before, during and after the field trial. Together with the results recorded by the alcolocks and evaluation meetings with the different stakeholders involved in each of the trials, the feasibility and practicability of alcolock implementations in a European context was evaluated. From these interviews, and from the data recorded by the alcolocks, it appeared that alcolocks are relatively practicable in both professional and non-professional contexts. Using the device did not interfere significantly with the drivers' tasks and was generally evaluated as easy. The general acceptance of the alcolocks was good and remained high throughout the entire twelve-month period. In the professional trials relatively few positive breath tests were recorded, whereas half of the offenders in the non-professional trial recorded ten or more failed breath tests. The hypothesis was confirmed that alcolocks may be marketed as an element of quality improvement. All together, the results showed that it is feasible to implement alcolocks in different professional and non-professional contexts, on the condition that the introduction of the devices, the inclusion process and the monitoring procedures are carefully prepared.
