In this situation, why do you have to wait before turning right?

Your answer is correct because, according to German traffic rules, when turning right at an intersection, you must yield to pedestrians crossing or about to cross the street you are turning into. This is to ensure their safety and avoid accidents. Additionally, you must also watch out for cyclists who may be continuing straight or turning, especially if they are on a bike lane adjacent to the road you are turning onto. Both pedestrians and cyclists have priority in these situations.

The blue car parked on the right side does not require you to wait, as parked vehicles do not have right of way unless they re-enter traffic. Therefore, the presence of the pedestrian and the cyclist are the main reasons you must wait before turning right here. Remember this rule for future situations: always yield to pedestrians and cyclists when turning to protect vulnerable road users and comply with the traffic regulations.
