Question Category: The driver's mental state
What should the driver do if they are driving and feel tired?
Explanation
"Driving when you are tired can be very dangerous, and it may cause you to micro-sleep (or nod off momentarily). At 100 km/h you travel at 28 metres a second, so if you micro-sleep for just 4 seconds you would travel over 100 metres without being in control of the vehicle. Never drive if you are fighting sleep."
