Thanks for your reply. In both the states of Michigan and Illinois they allow you to proceed and complete your turn.
MCL 257.612 states in part, " ...vehicular traffic facing the signal shall stop before entering the nearest crosswalk at the intersection or at a limit line when marked, but if the stop cannot be made in safety, a vehicle may be driven cautiously through the intersection."
The botXXXXX XXXXXne is, unless it is dangerous to stop, you must stop when the light turns yellow. The only exception is when you are preparing to make a left turn and you are already within the intersection. You can complete your left turn after oncoming traffic has stopped, even if the light turns red.
This rule seems to vary from state to state. For example, the Oct-98 printed edition of the Illinois Driver's Manual "Rules Of The Road" says: "If you enter an intersection when the light is green, you may finish your turn even though the light turns red" (Chapter Three: Traffic Laws - Right-Of-Way).
I can not find specifics for the State of Georgia. Any advice. I will definitely go to court go.
