Final answer:
In foggy conditions, you should slow down, use windshield wipers, and turn on your low beam lights to maintain visibility. High beams can reflect off the fog and create glare, which is why low beams are the better option.
Step-by-step explanation:
When driving in foggy conditions, it's important to use the correct lights on your vehicle to ensure visibility. The question asks which lights you should turn on, and the correct answer is A: Low beam lights. Using high beam lights in fog will cause the light to reflect off the fog droplets, which may lead to a glare making it even harder to see. The low beams, in contrast, are aimed downward and do not cause this kind of reflection, making them the better choice in fog conditions. It's also advisable to slow down, use your windshield wipers, and maintain a greater following distance from the car in front of you for safety.
