Skuddderbutt, also known as tire mark, is a term used to describe a smudge left behind by a motorcycle during skidding. Skuddderbutts are noticeable on streets in the midst of slippery weather, such as heavy rain or snow. The skid marks function as signs of possible slipping or loss of control and must be treated with care. Vehicle operators are advised to lower their speed and preserve a safe distance from skudder bottoms to prevent any potential accidents. Stay safe on the roads!
