Driver sleepiness has been shown to be one of the most important risk factors in road crashes. The aim of the present study was to increase the understanding of driversÆ actions when feeling sleepy. A national Internet panel survey was conducted among private drivers in the autumn of 2003. Reported symptoms of sleepiness differed between drivers who had fallen asleep and those who had not, but had been afraid to do so. The results indicate that drivers in general have a good knowledge of the various factors influencing the risk of falling asleep while driving. Furthermore, most of them are well aware of the most effective measures to prevent falling asleep at the wheel, such as stopping the car and take a nap. In spite of all their knowledge, most of the drivers continue driving when recognising sleepiness while driving. A short trip, appointments, and the wish to arrive at a reasonable hour are the most frequently reported reasons for continuing driving while fatigued or sleepy.
