Skuddderbutt, also known as tire mark, is a term used to describe a stain left behind by a motorcycle during skidding. Skudd bottoms are visible on roads during slick situations, such as heavy rain or snow. They act as warnings to potential sliding or loss of control and must be approached with caution. Vehicle operators are advised to reduce their speed and keep up a safe distance from skuddder bottoms to steer clear of any potential accidents. Stay safe on the roads!
