first check that is the signal is with camera or police is there it is your luck always take precaution.........lol
when you see green signal is on far slow down the car to the speed if you want to put your breaks on so you can, some signals do not blink during green and followed buy yellow and red, 6000 is too much i think people got signal phobia according to my thinking my experience is you should slow your car no matter some one giving you beep are flashes light think they are fools. be careful..... in future,
