Specifically, fog affects a driver in the following ways:
- Depth perception can be reduced due to the thickness of the fog.
- The low contrast caused by fog makes it difficult to distinguish between light and dark areas and objects on the road.
- Your vision fixates on what is close by due to something called the Mandelbaum Effect, an effect that causes your vision to rest at a distance of only three feet ...

Why is it dangerous to fly in fog?
The speed with which fog can form makes it especially hazardous. In a matter of minutes, visibility can drop from Visual Flight Rules (VFR) to less than a mile. Fog can also reduce visibilities below Instrument Flight Rules (IFR) minimum approach requirements.
Is heavy fog dangerous?
Fog is one of the most dangerous weather conditions that drivers face. Dense fog can decrease a driver's visibility to almost nothing. Every year, fog causes major pile-ups and numerous accidents when drivers are unable to see the road ahead of them.
