When doing long trips, you will eventually start getting 'tired' in game. This is shown to you by a message that takes up your GPS space saying "You are getting tired. You shold find a parking place to rest".
I have noticed that the screen will occasionally start blacking out but I have always rested before it got too bad.
Once this message starts showing, how long can you keep driving until you fall asleep?
Do you actually fall asleep at all?

Shortly after you've passed the time when the game says it's time for rest (F6 menu) it will begin charging you 150 euro every few minutes until you sleep. Not a big deal if you have an empire, but if you're still getting established it's worth knowing.
The only time you should drive while tired is when taking a rest break would cause you to deliver your cargo late.
