Skudder bottom, also known as skid mark, is a term used to describe a mark left behind by a motorcycle when it skids. Skudder bottoms are visible on streets during slippery situations, such as heavy rain or snow. These marks act as signs to possible slipping or loss of control and should be treated with care. Vehicle operators are advised to reduce their speed and maintain a safe distance from skudd bottoms to avoid any potential crashes. Stay safe on the roads!
