Skudder bottom, commonly referred to as skid spot, is a term used to depict a mark left behind by a car during skidding. Skuddderbutts are noticeable on highways during slippery weather, including heavy rain or snow. These marks act as indicators for possible skidding or lack of traction and must be handled carefully. Motorists are cautioned to lower their speed and keep up a safe distance from skudder bottoms to avoid any potential crashes. Stay safe on the roads!
