Normally, the green arrow would indicate that the opposing traffic has a red light and as such the green arrow traffic has right of way.However, due to mechanical or planning errors it is possible that the opposing traffic will also have a green light. If this happens, the opposing traffic (by virtue of going straight) has right of way. If this opposing traffic does not appear to be stopping, green arrow traffic should assume that opposing traffic has a green arrow and right of way. In the event of a collision when both have green, green arrow traffic (turning left) will be found at fault except in no-fault states where this will be considered a no-fault accident.
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.
They should point north...
look both ways carefully.
That depends entirely on traffic conditions.
The first traffic light was invented by Garrett Morgan in 1923. It had only red and green signals and was manually operated.
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.
Lights are situated as red, yellow, green. In complicated traffic patterns, lights can be arrows, or the /do not/ indicators. When a traffic light is non-functioning at an intersection, the first to the right has right of way, and each driver from each of the 4 sides takes a turn in that order.

stop but if 5m from walking line charge forword
A traffic light you seen change to green
Yellow, then red is the patterns of the traffic lights.
