What should you do if you are driving in foggy conditions?

Answer: C — Reduce your speed

In foggy conditions, visibility is reduced and it can be difficult to see other vehicles, road signs, and hazards. Therefore, it is important to decrease your speed to give yourself more time to react and avoid any potential crashes. Increasing your speed would only make it more dangerous in these conditions, as you would have less time to react. Similarly, using your high beams may seem like a good idea to improve your visibility, but it can actually reflect back off the fog and make it even harder to see. Signaling your turns is always important while driving, but reducing your speed should be the priority in foggy conditions.
