Actual and Perceived Risks of Apprehension for Speeding in Norway

A study on the actual and perceived risks of apprehension for speeding in Norway was conducted. The actual risk of apprehension was estimated by combining data on the speed of traffic and data on the number of citations for speeding. The risk of apprehension for minor violations was zero, which showed that both police officers and speed cameras allowed a safety margin before citing a driver for speeding. There was a dose-response relationship between the level of speeding and the risk of apprehension: the more severe the violation, the higher the risk of apprehension was. In general, however, the risk of apprehension for speeding was low and tended to be overestimated by drivers.
