You want to turn left at the next junction. What is the right course of action now?

Your answer is correct because according to German traffic rules, when you want to turn left at the next junction where vehicles are stationary ahead, you must first remain behind the stationary vehicles. This ensures that you do not cause a traffic obstruction or risk an accident by cutting in front of them prematurely.

Additionally, it is important to indicate your intention to turn left early. This signals to other road users, including those behind you and from the opposite direction, that you are planning to turn, allowing them to adjust their speed and behavior accordingly.

You should not drive carefully past the stationary vehicles on the left unless there is a dedicated lane or clear space to do so. Doing otherwise could be dangerous and is generally not permitted.

So, the correct course of action is to stay behind the vehicles waiting, and signal left in good time. This aligns with the rules of safe driving, communication, and courtesy on German roads.
