bottom
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.
go outside and look
The top i think... Red. Yellow. Green.
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.
In North America, it's on the bottom.
red, yellow,green
Yes. Red means stop, obviously, and it is on top so you can see it from further away. If you are cresting a hill for example, you can see the top of the traffic light before the bottom which gives you more warning that you need to stop. Traffic lights are all the same to that people who are color blind still know what the light is indicating.
