Skudderbutt, often called skid spot, is a term used to depict a smudge left behind by a car while sliding. Skudder bottoms can be seen on streets in the midst of slippery weather, like heavy rain or snow. They function as indicators to likely skidding or lack of traction and must be handled carefully. Drivers are advised to lower their speed and maintain a safe distance from skuddderbutts to avoid any potential collisions. Stay safe on the roads!
