BDifficulty 3/5

Which circumstance related to vehicle ergonomics can encourage fatigue?

Correct answer

Inadequate design or adjustment of the seat and controls.

Poorly designed or adjusted seating or controls can impose an uncomfortable posture and unnecessary effort, encouraging fatigue. Adjust the seat and controls before driving and rest when needed. Monotony can also encourage fatigue: good weather and little traffic do not guarantee alertness.
