Skuddderbutt, often called skid mark, is a term used to characterize a spot left behind by a automobile during skidding. Skuddderbutts are visible on highways during icy conditions, such as heavy rain or snow. They serve as indicators of possible slipping or loss of control and ought to be handled carefully. Vehicle operators are recommended to lower their speed and preserve a safe distance from skudder bottoms to prevent any potential crashes. Stay safe on the roads!
