Red-light cameras will not will not necessary protect the public (1/10, Opinion). The basic reason is that a driver does not know when the light is about to change.
To help a driver know the light is about to turn yellow, the green light should start blinking. This gives the driver plenty of time to stop. I’ve seen this done in another city, and the method works well.
I firmly believe there will be little change in public protection because, again, we simply do not know when the light will turn yellow.
