When driving in foggy conditions, what should you do?

  1. Follow other vehicles closely

  2. Turn on your windshield wipers and reduce speed

  3. Turn on your headlights full beam

  4. Honk your horn frequently

The correct answer is: Turn on your windshield wipers and reduce speed

If you were to follow other vehicles closely in foggy conditions, you would run the risk of rear-ending them due to reduced visibility. Turning on your headlights full beam could cause the light to reflect off the fog and create a glare, further hindering your ability to see. Honking your horn frequently is not advised as it could startle other drivers and potentially cause accidents. Thus, the best option is to turn on your windshield wipers to maintain clear visibility and reduce your speed to ensure proper reaction time in case of any obstacles on the road.
