When may you take the turn?

At a yield-controlled intersection in Germany, if you have a "Yield" sign, you must always give way to traffic on the priority road—here, the truck. You can only turn when it is absolutely clear you will not endanger or significantly impede the crossing traffic. If the truck driver clearly and unmistakably signals with a hand gesture that he is giving up his right of way, you may proceed—this must be a direct, visible manual signal to avoid any misunderstanding. You may not turn simply because the truck prompts you or tries to wave you through unless it is absolutely clear and safe. The main rule is: never risk crossing unless it is fully safe and all right of way is respected or visibly yielded by the other driver. This prevents accidents and confusion.
