Skudd bottom, also known as tire mark, is a term used to depict a mark left behind by a vehicle when it skids. Skuddbutts are noticeable on highways in the midst of slippery situations, including heavy rain or snow. These marks serve as warnings for likely sliding or lack of traction and should be approached with caution. Vehicle operators are advised to decrease their speed and preserve a safe distance from skuddbutts to avoid any potential accidents. Stay safe on the roads!
