Samenvatting
In September 1993, 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 province of Utrecht. Blood alcohol content (BAC), age and sex of the drivers were collected and recorded. If the recorded BAC level was 0.5 or over, places of origin of the offenders were also collected and recorded. The study was carried out on Friday and Saturday nights. The 1993 sample included 1375 motorists. The results of the 1993 survey are compared with the results of the 1992 survey.
