Correct answer: A. That there is a danger of themselves or other drivers falling asleep.
Driving when tired can be very dangerous and driver fatigue is one of the main causes of serious road collisions. If a driver becomes drowsy while driving, they should stop in a safe place take a caffeine-based drink and take a short nap. After this they should then get some fresh air and stretch their legs for a few minutes before setting off again. The only cure for fatigue is proper sleep. Never ever drive when tired.
