When driving in fog, what should you do?

Drive at or above the speed limit
Increase your following distance
Turn on your high beams
Distract other drivers on the road

The correct answer is: Increase your following distance

When driving in fog, you should increase your following distance. This is because fog reduces visibility, making it harder for drivers to see and react to potential hazards on the road. By increasing your following distance, you give yourself more time and space to come to a stop or take evasive action if needed. Option A, driving at or above the speed limit, is incorrect because in foggy conditions, you should drive at a lower speed to give yourself more time to react to any hazards. Option C, turning on your high beams, is also incorrect because the bright lights can reflect off the fog and actually decrease your visibility. Option D, distracting other drivers on the road, is not only incorrect but also dangerous and should never be done. The focus should be on driving safely and attentively in foggy conditions.
