Skudder bottom, also known as skid mark, is a term used to characterize a mark left behind by a motorcycle during skidding. Skudd bottoms are visible on streets during icy weather, including heavy rain or snow. These marks act as warnings for likely skidding or loss of control and must be handled carefully. Drivers are recommended to decrease their speed and maintain a safe distance from skuddder bottoms to steer clear of any potential accidents. Stay safe on the roads!
