Confusing Left Arrow Traffic Lights ??

[Gistok]

OK, in St. Clair Shores Little Mack Ave. is a 5 lane north/south street that crosses 10-13 Mile Rd's.

At 11 and 12 Mile Rd. intersections when thru traffic turns green, there is a solid blinking red light in the left turn traffic lantern. When the thru traffic turns red, the [[solid) left turning blinking red light changes to a green left arrow for about 10 seconds, and switches to a solid yellow light [[2 seconds) and then to a solid red. Easy to understand, and not confusing at all.

But recently at 10 and 13 Mile Rd. interchanges there is a different scenario played out that has caused a lot of noticeable confusion among left turning drivers [[I've seen folks backing up out of the intersection more than a few times). At both intersections at first there is a left green arrow [[20-30 seconds)... then it turns to a quick left yellow arrow [[2 seconds) followed by a quick [[solid) red [[2 seconds)... and then immediately a flashing yellow left arrow [[20-30 seconds). When thru traffic turns red, this yellow left arrow then turns into a solid red light... thus catching some drivers who are already in the turning lane by surprise.

I understand that some of this is due to only north or southbound thru traffic going at different intervals... but this blinking left yellow arrow has caught a lot of drivers off guard... especially when it turns solid red without warning, forcing some folks to back up, or finish their left turn when oncoming traffic has a green light.

Anyone else find these confusing blinking left yellow arrows around the metro area? ... I'd rather deal with a round-about!
