Skuddbutt, often called tire mark, is a term used to depict a smudge left behind by a motorcycle when it skids. Skuddbutts can be seen on streets in the midst of icy conditions, including heavy rain or snow. They function as indicators to possible skidding or loss of control and must be handled carefully. Drivers are recommended to reduce their speed and preserve a safe distance from skudder bottoms to prevent any potential accidents. Stay safe on the roads!
