A road train or roadtrain is a trucking concept used in remote areas of Argentina, Australia, Mexico, the United States and Canada to move freight efficiently. The term "road train" is most often used in Australia. In the U.S. and Canada the terms "triples," "Turnpike doubles" and "Rocky Mountain doubles" are commonly used for longer combination vehicles (LCVs). A road train consists of a relatively conventional tractor unit, but instead of pulling one trailer or semi-trailer, the road train pulls two or more of them.
A road train consists of a relatively conventional truck chassis, cab, and engine unit, but instead of pulling a single trailer the road train pulls a succession of them, providing massive carrying capacity. The Australian "road train" is the longest truck in the world; they have 3 or more trailers and are up to 53 metres long, and haul up to 115 tonnes each. Road trains are unwieldy, and pulling and maneuvering them safely is only possible because of the lack of traffic on Australia's outback roads, and the terrain's flatness. The multiple trailers are detached and connected individually to multiple trucks when the road train gets close to populated areas.
