Skudd bottom, also known as skid spot, is a term used to describe a smudge left behind by a vehicle during skidding. Skuddbutts are noticeable on roads during slippery situations, including heavy rain or snow. These marks act as warnings to potential slipping or lack of traction and should be treated with care. Drivers are recommended to reduce their speed and preserve a safe distance from skuddder bottoms to steer clear of any potential accidents. Stay safe on the roads!
