Abstract
In the fall of 1996, the SWOV Institute for Road Safety Research and six police control teams carried out a study into the use of alcohol by drivers in the Dutch province of Limburg. The aim was to establish the motorists' alcohol consumption in this province. Blood alcohol content (BAC), age and sex of the drivers were collected and recorded. If the recorded BAC level was 0.7 promille or over, places of origin of the offenders were also collected and recorded. The study was carried out on Friday and Saturday nights. The collected data were analysed using the Weighted Poisson Model (WPM). The 1996 sample included 1386 motorists. The results of the 1996 survey are compared with the results of the 1994 survey and the 1995 national survey.
