What should you do before driving if you are sleepy?

Getting some sleep before you drive is the best course of action if you're feeling sleepy. Sleep deprivation can significantly impair your ability to operate a vehicle safely, leading to reduced attention, slower reaction times, and increased risk of accidents. By ensuring that you are well-rested before starting a trip, you enhance your alertness and cognitive function, both of which are crucial for safe driving.

The other options may offer temporary relief but do not address the root of the problem. Drinking coffee might provide a short burst of alertness, but its effects can vary from person to person and won't compensate for a lack of sleep. Opening the windows for fresh air or turning up the radio may help you feel more awake momentarily, but they are not effective solutions to combat drowsiness. The most reliable way to ensure your safety, and the safety of others on the road, is to be well-rested before you start driving.
