Skudd bottom, also known as skid mark, is a term used to depict a stain left behind by a automobile during skidding. Skudder bottoms are noticeable on roads in the midst of slippery weather, including heavy rain or snow. They function as warnings for likely skidding or lack of traction and should be approached with caution. Vehicle operators are recommended to reduce their speed and keep up a safe distance from skudd bottoms to prevent any potential collisions. Stay safe on the roads!
