What is the right thing to do in this situation?

In this situation, the correct action is to wait before the junction. This is important because there is a traffic officer present, indicating that you must follow their directions rather than proceeding on your own judgment.

According to German traffic rules, when a police officer or traffic warden is directing traffic, you must always comply with their signals. In this case, waiting ensures safety for both pedestrians and vehicles, allowing for a controlled flow of traffic. Therefore, it's crucial to stop and wait for instruction before making any further movements.
