This differs depending on the intersection. Some intersections are forever flashing red. Some intersections only turn green when there is a trigger such as a pressure-pad or a crossing signal.
There is no specific length of time for a red light. Traffic engineers make that determination according to the flow of traffic.
It takes 2-3 minutes for a traffic light to change from green to red! (P.S I have counted the seconds myself!)
red light is used in traffic lights because red light has a "longer wavelength" than other colours
It is programmed by the people responsible for maintaining the light.
Red=stop red flashing= light is broken, use your judgement in crossing.

The fine for a red light violation is $450
The top i think... Red. Yellow. Green.
Yellow, then red is the patterns of the traffic lights.
Traffic approaching the light is to stop. If the way is clear, traffic can then proceed through the intersection.
The red flashing traffic light means that you are to come to a stop, yield to other traffic and then you can procede when the way is clear.
Yes if you run a red traffic light (in the UK)
