Final answer:
To drive safely in fog, reduce speed, increase following distance, use low beam headlights and fog lights, and improve visibility with windshield wipers and a defroster. Utilize sound for awareness but avoid excessive noise.
Step-by-step explanation:
When driving in fog, it is essential to take several precautions to ensure safety. Firstly, reduce your speed and increase your following distance to allow more time to react to any unforeseen hazards. It's crucial to use low beam headlights and, if available, fog lights, because high beams reflect off the fog, causing a glare that reduces visibility even further. Additionally, activating your windshield wipers and defroster helps improve visibility by clearing moisture from your windshield. Lastly, be aware of the sounds around you and use your horn sparingly to alert other drivers of your presence without causing unnecessary noise pollution.
