Detailed explanation-1: -You may misjudge distance. People instinctively judge that blurry objects are further away than clear ones. With fog reducing contrast and clouding your viewpoint, you are more likely to misjudge just how far away another car or stationary object is, making car accidents far more likely.

Detailed explanation-2: -There are more water molecules in the same amount of space in a fog. Fog cuts visibility down to one kilometer, meaning it will prevent you from seeing further away than one kilometer from where you’re standing. Mist can reduce visibility to between one and two kilometers.

Detailed explanation-3: -How come you can see fog from a distance but not up close? Often what you perceive as fog is actually the way the moisture in the air distorts the light passing through it to your eye. In many cases this effect is so slight that it can only be perceived for light traveling through long distances from things far away.
