Abstract
In the Netherlands, from 1986- 1991, annually a publicity campaign is held to counteract driving under influence. The target group of the campaigns is the young male driver. The campaign is evaluated by holding a survey amongst the drivers and observing the actual behaviour of drivers and cyclists. The results show that the DWI- problem is severe; one out of every eight observed car- drivers has a BAC of 0, 5 promille. / or more. With cyclists even 25% exceeds this limit. It is concluded that the joint influence of publicity, legal measures and law enforcement has led to a positive behavioural change amongst male drivers in the age group 18- 35.
