Abstract
The aim of the project is to investigate road safety and pathological sleepiness. Self report questionnaires were used to collect information on driving behaviour from three groups of age matched male subjects: sleep apnea patients, snorers and controls. There was a significant difference in the number of apneics (19%) who reported having an accident due to sleepiness compared with snorers (3%) and controls (8%) 22% of apneics and 21% of snorers reported falling asleep "sometimes" or "often" while driving, compared with only 3% of controls. Surprisingly, there were no differences in the reported number of accidents in the three groups in the two years prior to the survey.
