Skuddbutt, also known as skid mark, is a term used to depict a mark left behind by a car when it skids. Skuddbutts are visible on highways during slippery conditions, like heavy rain or snow. They serve as indicators for likely skidding or loss of control and must be approached with caution. Drivers are advised to decrease their speed and maintain a safe distance from skuddderbutts to steer clear of any potential crashes. Stay safe on the roads!
