You are driving with main beam lights on in darkness. When do you have to dip your headlights?

Your answer is correct. According to German traffic rules, you must dip your main beam headlights in two important situations: when a vehicle is approaching from the opposite direction, and when you are driving closely behind another vehicle. This prevents dazzling other drivers, which could cause dangerous situations. However, you do not have to dip the lights simply because there are pedestrians moving ahead in the same direction; the key is to avoid blinding other drivers. Remembering this helps maintain safety for everyone on the road during nighttime driving.
