The duration of a green light on a traffic signal can vary widely depending on the specific intersection, traffic conditions, and local traffic regulations. Typically, green lights last anywhere from 30 seconds to a couple of minutes. Some intersections may have adjustable timers that change based on real-time traffic flow. For precise timings, it's best to refer to local traffic authority guidelines.
It takes 2-3 minutes for a traffic light to change from green to red! (P.S I have counted the seconds myself!)
A green light usually last a minute to two minutes.
There is no exact time simply because no 2 intersections are the same, there are factors that change this time such as: How much traffic goes through the intersection on one direction?
Stale green light is a term used in traffic terminology. Essentially, it means that the green light has been green so long that it's about to turn yellow.

If you are blocking traffic flow for a long time then yes.
When the traffic light comes into view and it's green, it was likely green for a long time, unless you also observe cars just starting to get going. If you see the traffic light is green in the distance we call this green light "stale", meaning it could turn yellow any second. A traffic light that just turned green, we call this green light "fresh", meaning it just turned green and it won't be turning yellow for a little while. Of course these times between from when it turns green then back to yellow and red again varies on the intersection. To answer the question when you're approaching a green traffic light you should prepare to stop as that green light is "stale". You don't necessarily have to slow down just get ready to hit the brake.
The duration of a green traffic light varies based on factors such as location, traffic volume, and the specific traffic signal system in use. Typically, green lights can last anywhere from 20 to 90 seconds, but some may be shorter or longer depending on the intersection's design and traffic patterns. Traffic engineers adjust these timings to optimize traffic flow and ensure safety for both vehicles and pedestrians.
A light
There is no specific length of time for a red light. Traffic engineers make that determination according to the flow of traffic.
You can get a DOT card if you're color blind as long as you can distinguish between the red, amber, and green of a typical traffic light.
First, the leave grows into a light green color, Then to a dark green, Then to a yellow or orange color, Then to a brown color
