In the Fall of 1997, the SWOV Institute for Road Safety Research and police control teams conducted a roadside survey. The aim was to establish the motorists' alcohol consumption in the Dutch town of Oosterbeek. 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 1997 sample included 700 motorists. The collected data were analysed using the Weighted Poisson Model (WPM). The results of the 1997 survey are compared with the results of a similar survey, conducted in the rest of the province of Gelderland in the Fall of 1997, and with the results of the 1997 national survey.
