Conditions for speeding behaviour: A comparison of car drivers and powered two wheeled riders

Against a UK background of decreases in collisions involving car drivers, motorcycle collisions are on the increase. To throw light on this process, this paper explores differences between motorcyclists and car drivers in the conditions for speeding behaviour. Some predictions derived from the model of Task-difficulty Homeostasis (TDH) were tested using self-report data from samples of older (>35years), male car drivers (n=269) and motorcyclists (n=102). As predicted, riders were more likely to speed on rural roads and less likely to speed on urban roads, and, riders were much more likely to speed in daytime than at night.
