Show answer and explanation
Correct answer: Circumstances related to the road, the vehicle, and the driver.
Time behind the wheel is the main cause of fatigue, but many circumstances make it set in sooner. Some involve the road and surroundings, such as rain or a road surface with potholes; others involve the vehicle, such as an uncomfortable seat or poor ventilation; and others involve the driver, such as stress or hunger.
