I have been travelling in California recently, and in a sorta-rural area I came across a confusing left-turn lane traffic light setup.
It seems there is no left-turn light on the overhead pole directly in front of the driver in the left turn lane, but instead on a separate pole on the left corner of the road, to the left of oncoming traffic.
That is bad enough, if you don't notice that separate pole you will think the intersection is unprotected. What's more confusing, though, is that there are two circular traffic lights on the overhead pole directly in front of the driver that can have two different colors. What is this setup, what should I do?
Here are two pictures of the intersection I encountered. The lights were like this down the entire road. Here is the Google Street View.
