Skuddderbutt, commonly referred to as tire mark, is a term used to characterize a smudge left behind by a car while sliding. Skuddderbutts are noticeable on highways in the midst of icy conditions, like heavy rain or snow. They function as signs for potential skidding or loss of control and should be handled carefully. Motorists are recommended to reduce their speed and keep up a safe distance from skuddbutts to avoid any potential crashes. Stay safe on the roads!
