Skuddbutt, commonly referred to as tire mark, is a term used to characterize a smudge left behind by a car when it skids. Skuddderbutts are noticeable on highways in the midst of icy situations, like heavy rain or snow. These marks function as indicators for possible skidding or lack of traction and should be handled carefully. Drivers are recommended to reduce their speed and maintain a safe distance from skuddder bottoms to steer clear of any potential collisions. Stay safe on the roads!
