Consumption becomes greater than supply
If you had a bag of marbles, and there were two colours - red and green - and the ratio of the coloured marbles is two times the amount of green marbles to red marbles, you would have a ratio of 2:1

If you're in the intersection and it is green then turns to yellow/red, it is fine to go. Entering the intersection after it is already yellow is unlawful driving. GA
A traffic light is placed at an intersection of two or more roadways. Each approach of the intersection has at least one signal head with three bulbs (red, yellow, and green) facing it. Cars approaching the intersection can go through it if the light facing them is green and cannot go through it when the light is red. Signals go from green to yellow (to slow down for the red) to red and then back to green. Only one of the two roads at a signalized intersection can have a green light at one time and the traffic on the other road must wait for the light facing them to turn green.
It means you should stop and wait for a green light to go through the intersection.
A yellow light at an intersection indicates that the traffic signal is about to change from green to red. It serves as a warning for drivers to slow down and prepare to stop before the light turns red.
A yellow arrow at an intersection means that the signal is about to change from green to red, and you should prepare to stop or yield to oncoming traffic.
The blinking green light in Canada signifies that a driver can turn left at a traffic light intersection when it is safe to do so, even when the light is red. This is a unique traffic signal used in some Canadian cities to improve traffic flow and reduce congestion.
You complete the turn when it is safe to do so.
A red light on a street is where you must stop in the intersection. A red light on a street is where you must stop in the intersection.
A yellow arrow signal at a traffic intersection means that the signal is about to change from green to red, and you should prepare to stop if you are able to do so safely.
you must stop if traveling straight...you can go which ever way the green arrow is pointing, left or right.
When approaching an intersection and the traffic light changes from green to yellow, you should assess your distance from the intersection and your speed. If you can safely stop without skidding, it’s best to do so to avoid entering the intersection on red. However, if you are too close to stop safely, you should proceed through the intersection cautiously. Always be alert for other vehicles or pedestrians that might act unpredictably during this transition.
It means you're supposed to stop at that intersection and remain stopped while that signal remains red.It means that you are to come to a complete stop at that intersection, and proceed either when that signal changes to green, or, in the case of making a right turn, when the coast is clear and it is safe to proceed (provided right turns on red are permitted at that intersection).
