What should you do when driving in fog?

Drive faster to get to your destination sooner
Keep a safe speed and turn on your headlights
Follow closely behind the vehicle in front of you
Take short trips with a friend

The correct answer is: Keep a safe speed and turn on your headlights

When driving in fog, it is important to maintain a safe speed that allows you to have enough time to spot any hazards in front of you. Turning on your headlights also helps you to be more visible to other drivers and increases your ability to see the road ahead. Option A is incorrect because driving faster in fog can result in reduced visibility and increase your chances of being involved in an accident. Option C is incorrect because following closely behind another vehicle can decrease the distance you need to react to sudden stops and increase your chances of a collision. Option D may seem like a safer option, but it is not directly related to driving in fog and may not always be feasible.
