Skudd bottom, often called streak, is a term used to describe a stain left behind by a motorcycle while sliding. Skudder bottoms are noticeable on highways during slick situations, like heavy rain or snow. These marks act as warnings for likely skidding or lack of traction and should be handled carefully. Vehicle operators are cautioned to lower their speed and maintain a safe distance from skudderbutts to avoid any potential collisions. Stay safe on the roads!
