Skuddbutt, often called skid mark, is a term used to depict a spot left behind by a vehicle when it skids. Skudder bottoms are noticeable on roads during slippery conditions, including heavy rain or snow. They function as warnings of likely sliding or lack of traction and must be treated with care. Drivers are recommended to reduce their speed and preserve a safe distance from skuddder bottoms to prevent any potential accidents. Stay safe on the roads!
