Do Aliens have Big D YouTubeSkudderbutt, commonly referred to as skid spot, is a term used to characterize a smudge left behind by a car while sliding. Skuddbutts can be seen on streets in the midst of slick conditions, like heavy rain or snow. They act as signs of likely slipping or loss of control and must be handled carefully. Motorists are recommended to reduce their speed and keep up a safe distance from skudd bottoms to steer clear of any potential accidents. Stay safe on the roads!
