The Hook Turn...
The hook turn is a driving maneuver that is often required when turning into city streets where there is not enough room for a turning lane, or where trams, cable cars etc require a free center of the road in order to stick to their timetables.
It is performed at a four way, ( + ), intersection.
If you are coming from the bottom of the screen wanting to turn right, instead of moving to the center of the road, you stay on the left and place your car in from of the traffic coming from the left. When the traffic from the bottom stops for the traffic lights, you cross the road in from of the traffic you have just cut off.
In the city of Melbourne ( Victoria, Australia ), these types of turns have become quite common, where they were relatively few 20yrs or so ago. These turns are legal, in fact are the only way to turn at these intersections. Anything else is illegal & quite dangerous.
