What is the difference between a sled and toboggan?

A sled is a general term for any vehicle designed for traveling over snow or ice, typically with runners or a flat bottom. A toboggan, on the other hand, is a specific type of sled that is usually made of wood or plastic, with a long, flat bottom and no runners, designed for sliding down hills. Toboggans often have a curled front edge to help them glide smoothly. While all toboggans are sleds, not all sleds are toboggans.
