A traffic jam is building up here. What is the correct procedure?

Your answer is correct because it follows important German traffic rules for handling traffic jams, especially on highways. When a traffic jam is building up, you must do two main things:

1. Switch on your hazard warning lights if possible. This alerts drivers behind you that traffic is slowing down or stopping ahead, helping to reduce the risk of rear-end collisions.

2. Move as far as possible to the right side of your lane or road, which creates a clear channel on the left side for emergency vehicles like ambulances, fire trucks, or police cars to pass through quickly. This is called the "emergency corridor" or "Rettungsgasse" in German traffic law and is mandatory on highways.

Driving to the left side (option 3) is incorrect because it blocks this crucial space for emergency vehicles and can cause additional hazards. Always give way by moving as far right as possible. This practice is vital for safety and emergency response in traffic jams in Germany.
