What is the right course of action here?

In the scenario depicted, you are approaching an intersection where a red car is already on the road. According to German traffic regulations, the vehicle facing a stop sign (in this case, the red car) must yield to traffic on the main road. The green car, which has the right of way, can proceed without yielding, as long as it is safe to do so.

The correct answer emphasizes that the green car can move ahead of the red car, which aligns with the traffic rule that states vehicles must yield to those on the main road when signage indicates. It is important to recognize all relevant options when answering, as ignoring any can lead to misunderstandings about right of way and safety at intersections.

Understanding these rules is crucial for safe driving and avoiding accidents.
