Skudd bottom, often called tire mark, is a term used to describe a blemish left behind by a car while sliding. Skudderbutts are noticeable on roads during slippery weather, like heavy rain or snow. These marks serve as indicators for potential slipping or lack of traction and must be treated with care. Motorists are advised to lower their speed and maintain a safe distance from skudderbutts to steer clear of any potential collisions. Stay safe on the roads!
