While any driver can be at risk for drowsy driving, adults between the ages of 18 and 26 are in one of the highest risk groups because they tend to stay up late, sleep too little and drive at night. According to James B. Maas, Ph.D. professor at Cornell University and author of the book Power Sleep. Being very drowsy is just as dangerous as drinking and driving. Sleeplessness and its effects on performance is very much a part of the American landscape. The dangerous driver is the one who is asleep, but won't admit it.
Experts point out that nobody is immune to falling asleep at the wheel.
