What should drivers do in foggy conditions?

In foggy conditions, it is essential for drivers to use low-beam headlights and slow down. Low-beam headlights are designed to illuminate the road directly in front of the vehicle without reflecting off the fog, which helps enhance visibility. High-beam headlights are counterproductive in fog because they can create a glare that reflects off the fog and reduces visibility further.

Moreover, driving at a slower speed allows a driver to have more time to react to any obstacles or changes in traffic conditions that may be obscured by the fog. It enables better control of the vehicle in low-visibility situations, reducing the risk of accidents. Maintaining a safe distance from other vehicles is also crucial; thus, following closely is not a safe practice in foggy conditions, as it can lead to rear-end collisions if the driver in front suddenly stops or slows down. Following the speed limit can be misleading, as the safest speed in fog may be much lower due to the reduced visibility, making it essential to adjust speed based on current conditions.
