In the Summer and Fall of 1998, 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 West-Zeeuws-Vlaanderen-area. 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 1998 sample included 926 motorists. The collected data were analysed using the Weighted Poisson Model (WPM). The results of the 1998 survey are compared with the results of the 1995 Zeeland survey. Comparisons are made with the results of rest of the Dutch province of Zeeland and the whole Netherlands.
