Skuddder bottoms are visible on highways during slippery conditions, like heavy rain or snow. The skid marks function as warnings to likely skidding or lack of traction and ought to be handled carefully. Motorists are cautioned to reduce their speed and preserve a safe distance from skuddderbutts to avoid any potential collisions. Stay safe on the roads!
