Actually, both the ambidextrous point as well as the left arm elbow thing are legal forms of signalling. The ambidex point is more common globally, and I personally prefer the ambidextrous point because it's less ambiguous - you might be surprised how many people don't know what it means to point upwards with your elbow crooked.
Typical, full of shit Anon thinks he knows the law, actually doesn't. For someone so boastful of his bike experience he sure doesn't seem to know what's legal or not.
Boastful of their bike experience? Ha! Are we talking about the same device that most of us learn to master by the time we are 6? I'm going to start riding my Green Machine into traffic.
lithell ends with an excellent point -- a lot of dumbasses don't know what the left arm/90-degree thing means.....so i usually use my right arm to signal a right turn, lest they think i'm waving or something.....
all the same, the left arm IS slightly more visible, as it is closer to the traffic.
But holding your left arm up with a 90 degree elbow bend just looks like you are waving at somebody. That's silly. When a motorist can't see my right arm sticking out through my fat body I will look at losing a couple (hundred) pounds.
The left-handed right turn signal was invented for motorists who don't have the option of sticking their right arm out of the right window from the driver's seat.
Cyclists don't have that problem and there's nothing to block the view of my extended right arm from those behind me.
assuming that your comment wasn't some sad, unsuccessful attempt at sarcasm, you're a dumbshit.
TL;DR: Both hand signal styles are legal.
