Which of these statements about staying alert to drive is true?

The assertion that sleep is the only effective means to overcome fatigue is true because fatigue significantly impairs a driver's reaction times, decision-making abilities, and overall awareness. While short breaks or caffeinated beverages like coffee may provide temporary relief, they do not address the underlying fatigue-related issue effectively. Only adequate sleep restores cognitive function and physical stamina, enabling a driver to perform safely.

The suggestion that a half-hour break or coffee is sufficient overlooks the necessity of deep restorative sleep, which cannot be replaced by stimulating drinks alone. Stopping on the side of the road for a short nap may help momentarily, but it is not a substitute for adequate sleep. Lastly, turning up the radio might distract a driver rather than keep them alert, as it does not genuinely combat fatigue but rather serves as an ineffective cope mechanism. Thus, prioritizing proper rest is essential for safe driving practices.
