Samenvatting
In order to prevent road fatalities, police organizations all across the world have implemented various enforcement programmes (random breath testing, sobriety checkpoints, random road watch, photo-radar, mixed programmes and red-light cameras) that are designed to deter deviant driving behaviours, which significantly increase the risks of serious accidents. Our systematic review assesses the effect of tough police interventions. It appears that all of the evaluated studies--except three--led to an average decrease, ranging between 23 and 31 per cent, of accidents causing injuries. (Author/publisher)
