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

Feeling drowsy while driving significantly impairs your ability to operate a vehicle safely, similar to driving under the influence of alcohol. It is critical to address drowsiness as soon as it is recognized. Stopping at a safe location and taking a nap allows your body to rest and recover, which can help restore your alertness and focus. Short naps, typically around 20 minutes, can be particularly effective in reducing drowsiness and improving overall driving performance.

The other choices may seem like quick fixes but can lead to dangerous situations. Pushing through fatigue increases the risk of falling asleep at the wheel, leading to accidents. Turning up the radio and singing may temporarily engage your mind but does not address the underlying issue of tiredness and could still result in impaired judgment or slow reaction times. Rolling down the window for fresh air might provide a momentary sense of alertness but is unlikely to combat the significant impairment caused by drowsiness. Therefore, the best and safest choice is to take a break and rest.
