You are driving in the left of two lanes and approaching a vehicle that has just started to overtake. What do you do?

Your answer is correct. When another vehicle begins overtaking on a multi-lane road and you are driving in the left lane, you must keep a safe distance behind the vehicle in front of you and allow it to overtake safely. This helps avoid dangerous situations and ensures the overtaking maneuver can be completed without stress or risk. German traffic rules clearly prohibit closing up to the vehicle or using your horn and lights aggressively, as that can endanger all involved. In summary, patience and maintaining space help everyone stay safe during overtaking situations.
