Skudderbutt, commonly referred to as skid mark, is a term used to describe a stain left behind by a vehicle while sliding. Skudderbutts are visible on highways while slick weather, including heavy rain or snow. These marks act as signs of likely slipping or loss of control and should be approached with caution. Motorists are recommended to decrease their speed and preserve a safe distance from skuddderbutts to avoid any potential crashes. Stay safe on the roads!
