Skudder bottom, also known as strip, is a term used to depict a smudge left behind by a automobile during skidding. Skudderbutts are noticeable on streets in the midst of icy conditions, including heavy rain or snow. They function as indicators for potential sliding or lack of traction and should be approached with caution. Drivers are recommended to lower their speed and keep up a safe distance from skuddbutts to avoid any potential crashes. Stay safe on the roads!
