The translation for the truck itself is pretty wrong in every sentence.
For example; When you need to put your truck in front of the trailer it says "Je moet je tractor voor de oplegger zetten"
"Tractor" is wrong here as that's an agriculture vehicle. So it needs to be "trekker"
I've saw other senteces to with "tractor", but that doesn't even apply in ETS unless it's a cargo you transport.
But "tractor" needs to be "trekker" as it's the pulling vehicle for the trailer.
Kind regards
