Accidents in Fog More Deadly Than in Rain or Snow

      Fewer car accidents happen in foggy weather than in rain or snow, but if they do they tend to be more fatal, a study suggests.

      The Korea Road Traffic Authority analyzed 1.12 million car accidents between 2011 and 2015 and found that the fatality rate in foggy weather was 10 percent, compared to just two percent for clear days.

      That means one in 10 collisions in foggy weather kills someone, whereas accidents in rain and snow only have a fatality rate of three per 100. On cloudy days the fatality rate is four percent, apparently because more people drive carelessly.

      The vast majority of car accidents or 85 percent happen in clear weather because there is seemingly nothing to worry about.

      Only 8.56 percent occur on rainy days, 4.68 percent on cloudy days and 0.85 percent in the snow. Just 0.17 percent take place in foggy weather, when many people do not drive at all.

      "Visibility declines by about 20 to 30 percent in rain or snow and 50 percent in the fog, so drivers have to slow down, either because the roads are wet or they can't see very well," said Lee Jeom-jae at the Korea Road Traffic Authority.
