Skudderbutt, often called skid mark, is a term used to describe a mark left behind by a vehicle during skidding. Skudd bottoms are noticeable on highways in the midst of slick conditions, such as heavy rain or snow. The skid marks function as warnings of potential slipping or lack of traction and should be treated with care. Vehicle operators are cautioned to decrease their speed and preserve a safe distance from skudderbutts to avoid any potential collisions. Stay safe on the roads!
