Do Aliens have Big D YouTubeSkuddderbutt, also known as tire mark, is a term used to depict a blemish left behind by a car when it skids. Skudder bottoms can be seen on roads during slippery weather, such as heavy rain or snow. These marks function as indicators of likely sliding or lack of traction and must be approached with caution. Motorists are recommended to reduce their speed and maintain a safe distance from skudderbutts to steer clear of any potential accidents. Stay safe on the roads!
