Skuddder bottom, also known as skid mark, is a term used to characterize a stain left behind by a motorcycle while sliding. Skuddderbutts can be seen on roads during slick situations, like heavy rain or snow. The skid marks function as indicators to likely slipping or lack of traction and must be treated with care. Vehicle operators are recommended to decrease their speed and preserve a safe distance from skuddbutts to steer clear of any potential crashes. Stay safe on the roads!
