The Skellefte Model is a project whose purpose is to reduce the number of repeated drunk driving offences by improving cooperation between the police, social services, addiction treatment systems, county administrative boards, public prosecutors, judges and the criminal justice system. The project's key concept is that suspected drunk drivers must come into contact with municipal social services or be taken care of by the county council addiction treatment system as quickly as possible, and preferably within 24 hours after being apprehended and questioned by the police. The evaluation indicates that the Skellefte Model is socio-economically beneficial. A majority of those who are working in the project also believe that the model works well, but that there are numerous problems, such as administrative problems and routines, a need to better embed the model among administrators, etc. The evaluation also shows that there is room for improvement in the handling of drugged drivers. The results differ greatly from county to county. The inter-county differences are likely due to factors such as when the project began and discrepancies in terms of the application of routines, motivation and embedment among employees. They may also be attributable to some extent to the fact that some aspects of the Skellefte Model are being applied in different ways and adapted to disparate local and regional conditions.
