What is a "skid lid"?

A skid lid, also known as a crash helmet, is a slang term for a motorcycle helmet. It is commonly used in the United States and refers to the protective headgear that motorcyclists wear to protect themselves while riding. Skid lids come in a variety of shapes, sizes, and styles, ranging from full-face helmets to open-face helmets. They are made from materials such as polycarbonate, fiberglass, and carbon fiber, and are designed to provide protection from impacts and abrasions in the event of a crash or fall. Many skid lids also come with additional features such as vents, visors, and communication systems to enhance the rider's experience.
