What should you do in this situation?

In this situation, the correct actions are to allow the pedestrian to cross the road and to wait until the blue vehicle has made its turn. According to German traffic laws, pedestrians have the right of way at pedestrian crossings, and as a driver, you are obliged to prioritize their safety.

By waiting at the crossing until the blue vehicle has completed its turn, you ensure that no confusion or danger arises from sudden movements, which could endanger the pedestrian or yourself. Pulling up directly behind the blue vehicle would obstruct the pedestrian crossing and could lead to a traffic violation, as you're not providing a clear passage for pedestrians.

Thus, both actions 1 and 2 are essential for maintaining safe traffic flow and protecting pedestrian rights.
