If you are driving in fog what should you do?

Use your parking lights
Increase your speed
Reduce your speed
Turn off your lights

The correct answer is: Reduce your speed

When driving in fog, it is important to reduce your speed as visibility is diminished. Using your parking lights (option A) will not provide enough illumination and may confuse other drivers. Increasing your speed (option B) is dangerous as you may not be able to avoid obstacles or other vehicles in the limited visibility. Turning off your lights (option D) is also dangerous as other drivers may not see you and you may not be able to see their headlights in order to stay in your lane. Reducing your speed is the safest option as it gives you more time to react to any potential hazards.
