Fog creates the illusion that you’re driving slower
RADIATION FOG
This type of fog forms during mild weather, when there is little wind and the skies are clear of other clouds. The lack of cloud coverage enables Earth’s surface heat to escape towards space. The air near the ground cools and condenses into a layer of fog, which grows overnight as the air cools further. When the Sun heats the air again the following day, the fog dissipates.
