What must you do if wild animals suddenly appear in the full beam of your headlights?

Your selected combination is correct because both actions, immediately dipping your headlights and sounding the horn while braking, are essential for ensuring road safety when wild animals appear in your headlights. Dipping the headlights helps to prevent blinding the animal, giving it a chance to move away safely, while sounding the horn and braking can alert the animal of your presence, potentially preventing a collision. According to the German traffic rules, these actions are necessary to prioritize safety for both the driver and wildlife, emphasizing the importance of immediate responses in unexpected situations on the road.
