How can you improve visibility when driving in fog?

• A. Use high beam headlights
• B. Use low beam headlights and reduce speed
• C. Open the windows to let fresh air in
• D. Use fog horns

Answer: (B)

Using low beam headlights and reducing speed is the most effective way to improve visibility when driving in fog. Low beam headlights are designed to illuminate the road directly in front of your vehicle without reflecting off the fog or moisture in the air, which can create a blinding glare. This helps to ensure that you can see the road, as well as make you visible to other drivers. Furthermore, reducing speed in foggy conditions is crucial because it allows for more time to react to obstacles or sudden changes in the environment. Fog can severely limit visibility, making it difficult to see other vehicles, pedestrians, or road signs. By driving at a slower speed, drivers can maintain better control over their vehicle and make informed decisions as they navigate through reduced visibility. In contrast, using high beam headlights can actually worsen visibility in fog, as the light reflects off the water droplets, creating a wall of light that can be distracting. Opening windows for fresh air does not directly enhance visibility and can distract the driver, while using fog horns is not relevant for improving visibility but rather for alerting other vehicles of your presence in low visibility conditions. Therefore, the combination of low beam headlights and reduced speed is the safest and most effective strategy for driving in fog.
