Skuddder bottom, also known as skid spot, is a term used to depict a stain left behind by a vehicle while sliding. Skudder bottoms are visible on highways in the midst of slippery conditions, such as heavy rain or snow. The skid marks function as warnings to potential skidding or lack of traction and should be handled carefully. Drivers are cautioned to lower their speed and preserve a safe distance from skudderbutts to prevent any potential accidents. Stay safe on the roads!
