Skudder bottom, commonly referred to as tire mark, is a term used to describe a stain left behind by a car while sliding. Skuddderbutts are noticeable on roads while icy weather, such as heavy rain or snow. These marks function as signs to potential sliding or loss of control and must be handled carefully. Motorists are advised to reduce their speed and keep up a safe distance from skuddderbutts to avoid any potential collisions. Stay safe on the roads!
