If you feel sleepy while driving, what should you do?

When feeling sleepy while driving, the most effective and safest choice is to open a window for fresh air. This action can help momentarily alleviate drowsiness, providing a brief boost in alertness that might help you stay awake. However, while opening a window may offer some immediate relief, it is important to recognize that it does not substitute for a more effective and responsible solution—stopping the vehicle in a safe location to rest or nap.

The other options lack efficacy and may increase driving risks. Increasing speed can lead to a loss of control and a greater likelihood of accidents, especially when drowsy. Turning up the volume of music might not address the underlying fatigue and can also lead to distractions, making it more challenging to focus on the road. Ultimately, if sleepiness persists, the best practice is to find a safe place to park and take a proper nap before continuing to drive.
