Question

Difficulty: MediumDriver Fatigue and Sleep Management

Accumulated sleep debt resulting from successive periods of insufficient rest can only be eliminated by obtaining adequate restorative sleep, as the human brain cannot condition itself to adapt to chronic sleep deficits.

Answer: Answer

Answer

True
The statement is true because sleep debt represents a physical and neurological deficit that accumulates when a driver receives less than the required amount of rest across consecutive days. The human body cannot build tolerance or adapt to sleep restriction, making restorative sleep the only effective cure to restore safe operational alertness.

Step-by-Step Solution

1
Analyze the biological mechanism of sleep debt accumulation in commercial driving.
Sleep loss accumulates across successive shifts, progressively degrading neurological processing, judgment, and physical reaction speeds.
Recognizing the physiological nature of fatigue is necessary to evaluate driver fitness.
2
Evaluate whether human physiology allows adaptation to chronic sleep deprivation.
Human biology cannot adapt to chronic sleep loss; only obtaining adequate restorative sleep eliminates accumulated sleep debt and restores cognitive performance.
Commercial driver regulations and safety research emphasize that sleep is the sole physiological cure for driver fatigue.
