Using low beams when driving in heavy fog is essential for maintaining visibility and safety on the road. High beams can actually worsen visibility during foggy conditions because they reflect off the water droplets in the fog, creating a glare that makes it harder to see. Low beams, on the other hand, are designed to provide adequate illumination of the road directly in front of your vehicle without creating excessive glare.

This reduced glare allows for better vision of the road and any obstacles, helping you navigate more safely through fog. It's also important to note that using flashers or parking lights can be misleading for other drivers and may not provide sufficient light to see the road, which can increase the risk of accidents. Therefore, low beams are the appropriate choice for driving in heavy fog conditions.
