Why are you required to wait now?

You answered correctly by choosing cyclist and blue vehicle. When you want to turn left in Germany, you must always yield to oncoming traffic coming straight or turning right—in this case, the blue vehicle. Additionally, if a cyclist is crossing your path as you turn, you must wait for them as they have priority. The yellow car is not in this situation, so it does not have priority. Remember: for left turns, you must yield to all oncoming vehicles and crossing cyclists or pedestrians. This ensures safety during the turn and prevents accidents.
