In British English, does the word "sleigh" usually indicate a horse-drawn vehicle?
And "sled" a vehicle that coasts under the influence of gravity?
In American English:
Sledge: heavy vehicle drawn by animals, usually for carrying cargo
Sleigh: light vehicle drawn by animals, usually for passengers
Sled: a light vehicle for coasting or, generally, something with runners for dragging something heavy maybe over dry ground rather than snow or ice
Toboggan: the specific type of coasting sled that is flat-bottomed and curled at the front; for several riders
