So I've just started riding. And when I'm on the street, this comes up frequently. SOme of the lights at intersections here are activated by sensors. My motorcycle doesn't set them off much less a bicycle. At these intersections, I stop, look both ways and proceed in the direction I need to. This is not legal but failing sitting there til a car comes to activate the sensor I see no option.
I also note that here in GA and other states, legislatures are looking at passing laws allowing motorcycles (and bicycles) to turn left on a red if the light doesnt change after a certain interval.
Here's a link to one state with left turn law
