Skudd bottom, also known as skid mark, is a term used to describe a mark left behind by a car during skidding. Skudderbutts are visible on roads in the midst of slick weather, like heavy rain or snow. The skid marks function as indicators for potential sliding or loss of control and must be handled carefully. Drivers are recommended to reduce their speed and keep up a safe distance from skuddbutts to avoid any potential crashes. Stay safe on the roads!
