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

Your answer is fully correct. When you intend to turn left at the next junction, you should do two things in advance: remain behind the stationary vehicles and indicate left.

This serves two important purposes according to German traffic rules: First, by staying behind the stationary vehicles, you do not try to overtake or pass on the left side, which can be dangerous and is usually prohibited in such situations. Second, by signaling your intention to turn left early, you give clear warning to other road users and pedestrians, helping to avoid confusion or accidents.

Driving carefully to the left past stationary vehicles without waiting is not correct, as it could be unsafe and violate traffic regulations. Always wait behind, signal early, and then make your turn safely.

This rule helps maintain orderly traffic flow and ensures safety at junctions.
