Fatigue and Lack of Alertness.

Fatigue (being tired) and lack of alertness are bigger problems at night. The body’s need for sleep is beyond a person’s control. Most people are less alert at night,especially after midnight. This is particularly true if you have been driving for a long time. Drivers may not see hazards as soon or react as quickly, so the chance of an accident is greater.

If you are sleepy, the only safe cure is to get off the road and get some sleep. If you don’t, you risk your life and the lives of others.
