Just in the Autobahn near Koln I saw this no entry sign (behind the grey vehicle near the center.)
If you observe the no entry sign is there, but probably useless, like all of the vehicles in the highway are going the other way.
I wonder if it's necessary for that sign to be placed there, or what - probably a misplaced sign or something...
Note: that there is a bit of graphic issue found on the 1st pic, like the grey vehicle and the missing land on the left. Don't worry, it's just a hiccup when I tried to picture it through ets2 photo studio. It can be also the graphic mod that I used.
