Explained in plain English

How dangerous is fog?

Fog significantly reduces visibility, making driving treacherous. The 30-car pile-up on the M20, causing serious injuries, highlights this danger. Studies show fog is often underestimated, leading to more multi-vehicle collisions than other weather conditions like heavy rain or even light snow, as drivers fail to adjust speed adequately.
