After overtaking you, a car pulls back into lane without leaving sufficient space in front of you. What should you do?

Your answers are correct. When a car overtakes and returns to your lane without leaving enough space, you should stay calm to avoid escalating the situation and brake gently to reestablish a safe following distance. Flashing your headlights at the other driver is not appropriate as it can provoke conflicts or be seen as aggressive. In German traffic law, keeping a cool head and maintaining safety is always the priority; reacting calmly and adjusting your speed ensures everyone’s safety and helps prevent accidents. Remember to never respond to another driver’s mistake with aggressive behavior.
