What should you do when driving in foggy conditions?

Use your high beam headlights.
Follow closely behind the vehicle in front of you.
Slow down and use your low beam headlights.
Pull over and wait for the fog to clear.

The correct answer is: Slow down and use your low beam headlights.

Driving in foggy conditions can significantly reduce visibility on the road, making it dangerous for all drivers. Using high beam headlights may seem like a good idea, but it can actually make it harder to see since the light reflects off the fog. It's important to also keep a safe distance from the vehicle in front of you, so following closely is not a safe option. Pulling over and waiting for the fog to clear may be tempting, but it's best to slow down and use your low beam headlights so you can maintain control of your vehicle and be visible to other drivers on the road. This will help you to stay safe and aware of your surroundings while driving in foggy conditions.
