Using low beams and fog lights in heavy fog is the recommended approach because these lighting options are designed to enhance visibility in adverse weather conditions. Low beams provide adequate light without causing reflection off the fog, rain, or snow, which can occur with high beams. High beams can actually make visibility worse in foggy conditions, as the light reflects off the water droplets in the fog, creating a glare that can hinder your ability to see.

Fog lights, on the other hand, are specifically designed to illuminate the road immediately in front of your vehicle, reducing the amount of light that reflects back from the fog. This combination allows a driver to see the road clearly without overwhelming the conditions with excessive brightness. Therefore, using low beams alongside fog lights creates the optimal visibility for navigating through dense fog safely, enhancing both your safety and the safety of others on the road.
