In heavy fog conditions, reducing speed is essential for maintaining control of the vehicle and ensuring safety. Slowing down allows drivers to react more appropriately to obstacles and other vehicles that may not be visible until they are much closer. Fog can significantly reduce visibility, often to just a few feet, making it difficult to gauge distances and find safe stopping distances.

At slower speeds, drivers can better assess their surroundings, have more time to react to sudden changes in traffic or road conditions, and minimize the chances of an accident. Additionally, other drivers will also be moving at slower speeds, which helps establish a safer driving environment overall.

Using high beam headlights in fog can cause light to reflect off the moisture in the air, creating glare that actually reduces visibility further, and frequently changing lanes can increase the risk of collisions since visibility and judgment are compromised.
