Question 7681
What are the three groups into which all the factors that promote or contribute to driver fatigue are grouped?
- Vehicle factors, driver factors, and external or seasonal factors.
- Driver factors, external or seasonal factors, and weather conditions.
- Vehicle factors, driver factors, and the layout of the controls and indicators.
Show answer and explanation
Correct answer: Vehicle factors, driver factors, and external or seasonal factors.
Things that contribute to fatigue can come from the driver, such as spending many hours behind the wheel without resting; the vehicle, such as poor ventilation or awkward controls; or outside conditions, such as heavy traffic, rain, or fog. Weather is one of the external factors, and controls are a vehicle factor, so neither forms a separate group.
