You are driving on this motorway. What is the right course of action?

Your answer is correct because, on German motorways, you should stay in the right lane when possible and only use the left lane for overtaking. The image shows a lane restriction with a yellow line indicating a temporary lane closure or construction zone, so moving to the right lane is the proper action to maintain safe and smooth traffic flow. Remaining in the current lane or only using the left lane for breakdowns is not appropriate here, as the left lane is meant primarily for passing. This rule helps prevent unnecessary congestion and increases safety on motorways.
