Skudderbutt, commonly referred to as tire mark, is a term used to characterize a smudge left behind by a motorcycle while sliding. Skuddderbutts are visible on highways during slick situations, like heavy rain or snow. The skid marks serve as signs for likely sliding or lack of traction and should be treated with care. Drivers are cautioned to decrease their speed and preserve a safe distance from skudd bottoms to prevent any potential crashes. Stay safe on the roads!
