abstract="Concentrated police enforcement has been shown to positively influence driver behaviour, but is difficult to apply to rural contexts. Signs warning of police enforcement in high crash-risk areas were placed in two rural locations in South Australia. The effects of these signs on vehicle speed were evaluated by conducting radar surveys of mean speeds on the approaches to, and exits from, the sign locations before and after their erection. A minor speed reduction on the exit from one of the signs was observed, but this was not observed in the speeds of the fastest 15 per cent of vehicles. This suggests that the highest risk group of speeders was not affected by the signs. The signs did not affect heavy vehicle speeds. It is not considered likely that the signs will have a substantial effect on road safety in rural areas.   <p>Language: en</p>",
