 The term controlled motorway is sometimes used for schemes that use variable speed limits without hard-shoulder running (for example, the M25 motorway from J27 to J30).As of 2019, smart motorways are mainly found in Great Britain, although the concept is also becoming common in Australia and New Zealand and some parts of Switzerland.The traffic management technique, including hard shoulder running, was first used in its full specification in the UK on the M42 motorway in the West Midlands in 2006.
