In October 1995, the SWOV Institute for Road Safety Research and six police control teams conducted a roadside survey. The aim was to establish the motorists' alcohol consumption in the Dutch province of Friesland. 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 1995 sample included 1313 motorists. The results of the 1995 survey are compared with the results of the 1994 survey and with the results of the 1994 national survey.
