Hi. My boss' cousin is a Houston Police Officer and she said that the Police Officer informed her that in Texas, when turning left, there are 2 different signal signs; "Left Turn Signal" and "Left on Green Arrow Only".
"Left on Green Arrow Only" obviously means that you cannot turn left no matter what, until the green arrow gives you permission.
"Left Turn Signal" apparently means that if the traffic traveling in the same direction as you (before getting over into the turn lane) has a green light then you can turn left, even though your signal technically shows red, if no one is coming from the opposite direction.
Is that correct? I've tried to find an answer to this and even pulled the Texas Transportation Code & Regulations online but I cannot find the actual answer to this.
