The SLED is a four-wheeled vehicle that is pulled by horses or dogs, while the LUGE is a four-wheeled vehicle that is ridden down a track. The SLEIGH is a six-wheeled vehicle that is pulled by horses or dogs and is used for recreational purposes. All three vehicles are used to traverse snowy and icy terrain.
