When is it necessary to use fog lights?

• A. Only in sunny weather
• B. In dense fog, heavy rain, or mist
• C. At night without streetlights
• D. When driving at high speeds

Answer: (B)

Using fog lights is necessary in conditions where visibility is significantly reduced, such as during dense fog, heavy rain, or mist. Fog lights are designed to illuminate the road immediately in front of the vehicle in a way that minimizes the reflection off of water droplets in the air. This is crucial in foggy or rainy conditions, as standard headlights can create glare and make visibility even worse. In these situations, fog lights provide a low, wide beam that cuts through the fog or rain, helping drivers to see the road and any obstacles more clearly while also making the vehicle more visible to others. This specialized lighting aims at enhancing safety during adverse weather conditions where standard headlights fall short.
