Avoid highway hypnosis

Highway hypnosis — extreme drowsiness caused by a combination of repetitive visual stimuli and fatigue — is one of the most widespread driving hazards. When driving long distances, make frequent stops, during which you might take short naps or exercise. Exercise your eyes by reading road signs or shifting the focus of your eyes to different parts of the roadway. Make sure you are properly rested. If you notice yourself dozing off and losing concentration — STOP! Get the rest you need, and then continue.
