Skudd bottom, often called skid spot, is a term used to describe a spot left behind by a car while sliding. Skuddder bottoms are visible on roads during icy situations, such as heavy rain or snow. These marks act as warnings of likely slipping or lack of traction and should be handled carefully. Vehicle operators are cautioned to reduce their speed and preserve a safe distance from skudderbutts to avoid any potential accidents. Stay safe on the roads!
