Oakland County, Michigan will be seeing some new left turn traffic lights in the upcoming years. These new lights will feature 4 lights, instead of the current 3 light models. Rather than flashing the red to allow left hand turn motorists to yield and turn, the flashing yellow will indicate that “motorists are allowed to turn left when available gaps in oncoming traffic are present”. Working in Bloomfield Township, I have seen a few intersections that have new funny lights installed, but not hanging and activated. Looks like these are what they are. Guess it’s better, but the stoplight just looks so funny!
