When is the use of fog lights and low beam headlights permitted?

Answer: C — Both of these

Fog lights and low beam headlights are permitted when visibility is significantly reduced due to adverse weather conditions like fog or snowfall, as well as during heavy rain. The primary purpose of fog lights is to illuminate the road immediately in front of the vehicle without creating glare, which can be particularly hazardous in fog or snowy conditions. Low beam headlights are designed to provide adequate visibility without blinding oncoming traffic, making them suitable for use in both foggy and snowy conditions. Using fog lights in heavy rain also aids in improving visibility without reflecting off the rain, reducing glare for the driver. The combination of these two lighting options enhances safety while driving in poor visibility conditions, making their permitted use essential for safe travel under such circumstances.
