Yellow, then red is the patterns of the traffic lights.
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 green light on the traffic light is on the bottom. The yellow is in middle, the red is on top. However, in some municipalities, the traffic lights are not vertical, they are horizontal. In these instances, the green light is usually, but not always, the furthest to the right.
A traffic light you seen change to green
a fresh green light is when the traffic light has just turned from red to green
It is usually on the bottom of the traffic light.
The lowest light on a traffic signal is green. Some cities use traffic lights that are not arranges top to bottom but rather side to side. In this event the green light is usually the furthest to the right.
On a vertical display traffic signal the green light is on the bottom. On a horizontal display traffic signal it is to the right, but may depend on that state (or municipality's) practice.
Depends. If the light has a sign next to it that says 'Yield on green light' it means you can go when the light is green and there is no traffic coming from the opposite direction that could hit you. If there is no sign wait for the arrow.
A delayed green light means the opposing traffic gets a early green light. Your light will still be red. You have to wait.
A green light usually last a minute to two minutes.
A green traffic light means you may go, but only if safe to do so. If there is other traffic or pedestrians in the way, you may NOT go until safe, even if you "have the green light." Even if the other traffic or pedestrians are violating the law, you cannot go until it is safe.
The green light on a traffic light means to go ahead. If you "get the green light," you have permission to move ahead on whatever project you are dealing with.
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.
Green-Yellow-Red-Green For color blind people the traffic light would be upright and from top it would be. Red Yellow Green.
A green light on a traffic light set (in the UK) means automobile traffic is free to go. Walking out when commuter traffic lights are on green is a bad idea. Answer from @MunicipalSigns: In general: A steady GREEN traffic light means you can go through the intersection. You must yield to emergency vehicles and others as required by law. If you are stopped and then the light turns green, you must allow crossing traffic to clear the intersection before you go ahead. A GREEN arrow means you can safely turn in the direction of the arrow. There should be no on-coming or crossing traffic while the arrow is green. If you are turning left, a steady green traffic green light means you may turn but only when safe to do so. Oncoming traffic has the right-of-way. Be alert for signs that prohibit left turns. When turning right or left, watch for pedestrians crossing in front of your vehicle.
If the green arrow shows for the direction you want to turn then you obey the green arrow, the red light is for all other traffic. The green arrow basically overrules the red light for the direction of the arrow.
Depends on where the traffic light is located. Can be as little as 5 seconds to as much as 15 seconds between green and red. All depends on traffic flow.
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.
The top i think... Red. Yellow. Green.
Green. It's pretty much universal worldwide...
In North America, it's on the bottom.
A "Green Wave" is a sensor on the traffic lights that allows the main flow of traffic to continue to have a green light unless another car is to pull up in the other direction then the light would change to let the other car go.
It takes 2-3 minutes for a traffic light to change from green to red! (P.S I have counted the seconds myself!)
You don't have to wait any amount of time when the light turns green, when the light turns green that means the intersection is safe for you to proceed.
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.
