No, this was something mentioned as a joke on one of the local radio stations and is not true. The sensor that activates the turn arrow is normally at the stop bar. If you have pulled past the stop bar to make the turn, then the traffic signal believes that you have already made your turn and it drops the call for the turn arrows to come on. The traffic signal turns yellow before I have a chance to get across the intersection.
Many traffic signals operate fully actuated.
This means there are sensors in all directions of the intersection. The amount of green time depends on the amount of vehicles. The more vehicles, the longer the green will time out. If only one vehicle, then the minimum amount of green will time out and then service the other directions of travel. There is a pothole in a city street.
