Skudderbutt, also known as tire mark, is a term used to characterize a stain left behind by a motorcycle when it skids. Skuddder bottoms are noticeable on streets during icy weather, such as heavy rain or snow. They serve as warnings to possible sliding or loss of control and must be approached with caution. Motorists are recommended to reduce their speed and maintain a safe distance from skuddder bottoms to steer clear of any potential collisions. Stay safe on the roads!
