Abstract
Feeling sleepy is especially dangerous when you are on the road. Sleepiness slows your reaction time, decreases awareness, and impairs your judgement, just like drugs or alcohol. In fact, people who are very sleepy behave in similar ways to people who are drunk. Experts think that many fatal night-time single-vehicle crashes are caused by the driver falling asleep. Most people know how dangerous it is to drink and drive. But driving drowsy can be just as deadly as driving drunk. (Author/publisher)
