Final answer:
When driving in fog, use low-beam headlights to improve visibility, drive slowly, and avoid directly looking at bright lights to prevent impaired vision.
Step-by-step explanation:
If you absolutely must drive in fog, it's recommended to use your low-beam headlights on your car. This is because the use of high-beam headlights in fog can cause the light to reflect back into your eyes, which might further impair visibility. By using low-beam headlights, you minimize reflection and glare, making it easier to see the roadway and any potential hazards. It's also important to drive slowly and carefully, paying close attention to the road and your surroundings. Moreover, it's essential to avoid looking directly at bright lights, such as oncoming headlights, to prevent temporary blindness or vision distortion.
