@Ember @JoshJers And it is not an asshole thing to waste my time with something a simple google search would have solved? If they want to be lazy and use me as a searchengine, they will have to accept a lmgtfy link.

And yes, it is more effort. but only once or twice until they understood, i am not a search bot

@exocomics wait till you get to "umfahren" which is the opposit of "umfahren".

Luckily it is used differently in most cases like "ich habe etwas umfahren" = "i drove around something" vs "ich habe etwas umgefahren" = "i drove something over".
But the sentence "du musst das Schild umfahren" is absolutely valid and can mean "you have to drive around the sign" or "you have to drive over the sign". Its just pronounced differently when spoken.
