The Turn That Starts on the Wrong Side
Melbourne has a road rule that makes visitors go quiet: to turn right, you start from the left.
It's called a hook turn, and it's one of the city's best small details. Here's how it works, according to VicRoads. At an intersection with a "Right Turn from Left Only" sign, you approach from the far left lane with your right indicator on. You go forward into the intersection, stop to one side, and stay there until the lights on the road you're turning into go green. Then you complete the turn.
Strange, until you see what it's protecting.
It's for the trams
Where trams run along a road, a car waiting in the middle to turn right can block a tram behind it. The hook turn moves the waiting car out of the way. Travel Victoria describes this as keeping trams going straight ahead from being held up by right-turning vehicles, and notes that hook turns appear at some intersections in the CBD, South Melbourne and Carlton.
It's older than you might think. Time Out Melbourne reports that hook turns are mentioned in Victorian road regulations of 1939, and that they were formalised in the 1950s as congestion grew. A 1954 newspaper report in Trove, from the National Library of Australia, reports on a change to the turning rules and says that where tram lines cross, the right-hand turn would stay as it was: the driver draws to the left kerb and waits.
Does it actually help?
Time Out cites a 2011 study by Monash University researchers Graham Currie and James Reynolds. They found that a hook turn saves a tram between about 11 and 16 seconds per intersection. That sounds small. The article says that without hook turns, extra trams would be needed to make up the delays, at an estimated cost of $15 million to $25 million.
The same study found hook-turn intersections were safer, which Currie attributes to there being fewer right turns across traffic. But he also says plenty of people are scared of them: according to the article, 39 per cent of Melbourne drivers will go around the block making left turns instead.
I love that last number. It means a rule can be good for the whole city and still be a bit frightening for each person doing it.
The word itself
I also like the name. "Hook turn" is exactly what it says: you swing out one way and hook back around. It's a plain, physical word, the kind you don't need to explain twice. Visit Melbourne once, do one, and you never forget what it means.
That is the kind of word I'd like this blog to collect: ordinary ones that carry a whole piece of how a place works.
