What is the main action required when driving in foggy conditions?

In foggy conditions, visibility is often severely reduced, making it essential for drivers to adjust their driving behavior to ensure safety. Reducing speed allows drivers more time to react to potential hazards, such as other vehicles, pedestrians, or obstacles that may not be immediately visible. Additionally, increasing the following distance provides a greater buffer between vehicles, which is crucial in low visibility situations where stopping distances can be longer than expected. This combination of slowed speed and increased distance helps maintain control and decreases the likelihood of collisions in foggy conditions.

Using high beams, while it might seem like a way to improve visibility, can actually create glare when the light reflects off the fog, making it harder to see. Driving at the speed limit does not take into account the specific risks associated with fog, as conditions may require a slower, more cautious approach. Signalling for turns frequently, while important in all driving conditions for communication, does not directly address the immediate risks posed by reduced visibility in fog. Therefore, reducing speed and increasing following distance is the most effective strategy for maintaining safety in these challenging conditions.
