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 United States 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, a road train pulls two or more of them.
There is also a special version of Road Train called B-double or B-Train which has its own access tag bdouble=*.
