Snowmobile
A snowmobile, also known as a snowmachine (chiefly Alaskan), motor sled (chiefly Canadian), ski-doo (Ontario and Quebec, dated proprietary eponym), motor sledge, skimobile, snow scooter, or simply a sled is a motorized vehicle designed for winter travel and recreation on snow. Their engines normally drive a continuous track at the rear, while skis at the front provide directional control.
