If you find yourself feeling drowsy while driving, what is the safest action to take?

When feeling drowsy while driving, the safest action is to find a safe place to pull over and rest. This is crucial because drowsiness significantly impairs your reaction time, decision-making, and overall driving ability, much like alcohol intoxication. Stopping to rest allows you to recharge and regain focus, significantly reducing the risk of an accident.

Turning up the radio may provide a temporary distraction, but it doesn't effectively combat sleepiness and can lead to further complacency. Switching drivers can be an effective option if a qualified driver is available, but it may not always be possible, especially if you're alone. Driving faster to reach your destination is also dangerous; it increases the risk of accidents and does not address the underlying issue of fatigue. Thus, taking the time to rest safely is the most responsible and effective choice when experiencing drowsiness.
