A type of fly, quick and light one-horse drawn carriage. It features a closed square box in a square frame with two wheels as high as the vehicle. Inside the cab, there was enough space for two, up to three passengers (if squeezed).

They were protected by a high hood separating them from the driver operating the vehicle from a high sprung seat behind the body. The passengers could communicate with the driver through a trap door near the rear of the roof. The cab could be either open or closed; except from the hood, the passengers were additionally protected from the elements by folding wooden doors that enclosed their feet and legs, protecting their clothes from splashing mud.
The cab was introduced in England in the 1830s and was used as a carriage until the beginning of the twentieth century. It was designed and patented by Joseph Hansom, an architect from York. Hence the carriage was originally called hansom-cab.
