Feeling sleepy after driving for several hours is a clear indication that your body is signaling a need for rest. The best response to this situation is to park in a safe place and take a nap. This option directly addresses the root cause of drowsiness—fatigue. A short nap can significantly improve alertness and overall safety compared to trying to push through the sleepiness while driving.

Opening the window to breathe fresh air may provide a momentary feeling of alertness, but it does not effectively combat the underlying fatigue that causes drowsiness. Stopping for a strong cup of coffee might offer temporary stimulation due to caffeine, but it doesn't replace necessary sleep and may not be effective for everyone. Continuing to drive while feeling sleepy increases the risk of an accident, as fatigue can severely impair reaction times and decision-making abilities. Thus, taking a nap is the safest and most effective choice to ensure you remain alert and capable of driving safely thereafter.
