What is the right course of action?

In this scenario, the correct actions are to allow the blue vehicle to pass and make the turn before the green vehicle. According to German traffic rules, drivers facing a situation with multiple vehicles must prioritize the right of way according to the regulations posted and the traffic situation.

The blue vehicle, being on your right, generally has the right of way unless signage indicates otherwise. This means you must yield to it. The green vehicle is positioned such that you may turn before it, assuming you are clear to proceed without interfering with its path. Understanding these principles ensures safe navigation through intersections and compliance with traffic laws.

Recognizing who has the right of way in mixed traffic situations is vital for preventing accidents and promoting efficient traffic flow.
