Too Many Yellow Traffic Lights

After living in the state of Oregon for the better part of two years, I have come to the conclusion that there are too many Yellow traffic lights in this state. We have, Steady Round Yellow Traffic lights, We have steady Yellow Arrow traffic lights and we have blinking Yellow traffic light Arrows. These yellow lights are driving me crazy. You never know what the driver in front of you is going to do when they approach an intersection that has one of these yellow lights glowing. Will the driver stop? Will the driver make a left turn? Will the drive go through the intersection? Its like playing Russian roulette with a fully loaded gun !!!
In its never ending effort to protect all its citizens from any harm and simultaneously give all its citizens the complete freedom to do whatever they want, the state of Oregon has created a crazy quilt of Yellow Traffic lights. I don't know for sure but I am willing to bet that the only ones benefiting  from all these yellow lights are the police officers and townships that get to issue yellow light tickets and collect traffic fines.
