Skudder bottom, often called streak, is a term used to characterize a mark left behind by a vehicle when it skids. Skuddbutts can be seen on highways during slippery weather, like heavy rain or snow. They act as indicators for possible slipping or loss of control and should be handled carefully. Motorists are advised to reduce their speed and keep up a safe distance from skudderbutts to prevent any potential accidents. Stay safe on the roads!
