What should you anticipate in this situation?

In this scenario, you correctly chose that you need to anticipate both that the yellow car may turn left and that you might have to yield your right of way. Here’s why:

When approaching an intersection where the priority road bends (indicated by the "abknickende Vorfahrtstraße" sign), it's important to expect that vehicles approaching from side streets (like the yellow car) might want to turn or cross. While you have the right of way because you are on the priority road, situations can change quickly—other drivers may not always yield as they should, and you may need to react or even yield to prevent an accident. This is why anticipating the possible actions of others, and being prepared to yield despite having right of way, is a key rule in German traffic. Always approach intersections—especially those with priority road changes—with caution, attention to signals, and the assumption that other drivers or pedestrians might act unexpectedly. This defensive driving mindset helps prevent accidents.
