When may you take the turn?

Your answers are correct because German traffic rules require that you may only take the turn if you do not endanger or significantly impede cross traffic (option 2). Additionally, if the truck driver clearly signals with a hand gesture that they are giving up their right of way, you may proceed after confirming this (option 1). It is important not to rely solely on a hand signal, but also to ensure safety and right of way yourself before turning. You must never start the turn immediately just because another driver prompts you to do so (option 3 is incorrect), as you are responsible for yielding correctly and safely. This ensures orderly and safe traffic flow at yield signs and intersections in Germany.
