Skudderbutt, commonly referred to as skid mark, is a term used to depict a mark left behind by a automobile during skidding. Skudd bottoms are visible on roads during icy weather, such as heavy rain or snow. They function as signs to potential slipping or lack of traction and must be approached with caution. Drivers are cautioned to reduce their speed and maintain a safe distance from skuddbutts to steer clear of any potential collisions. Stay safe on the roads!
