A horse trailer or horse van (also called a horse float in Australia and New Zealand or horsebox in the British Isles) is used to transport horses. There are many different designs, ranging in size from small units capable of holding two or three horses, able to be pulled by a pickup truck or even a SUV; to gooseneck designs that carry six to eight horses, usually pulled by 1-ton dually-style pickups. There are also large semi-trailers that can haul a significant number of animals. In the UK, a horsebox may also refer to a motorised vehicle adapted to carry horses (generally known as a horse van in North America or Australasia), or a railway vehicle specifically designed to carry horses.
