Q #497 - What should you do if you begin to feel drowsy while you're driving?
You'll be putting other road users at risk if you continue to drive when you're drowsy. Pull over and stop in a safe place for a rest. Caffeinated drinks and a short nap can temporarily help counter sleepiness. If you're driving a long distance, think about finding some accommodation so you can rest for longer before continuing your journey.
Stop and rest as soon as possible
Turn the heater up to keep you warm and comfortable
