Hook turns were introduced in Melbourne as early as the 1930s, as a way to facilitate tram movement. These turns can save trams up to 15.64 seconds per intersection, adding up to a considerable number of minutes per day1. That’s an impressive feat for a city with the world’s largest network of trams2.
Hook turns are used by bicycles around Australia, and are also used by buses in two specific Adelaide turns. But you won’t see cars making them anywhere else in Australia.
