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.
From top to bottom: Green is on the top Yellow is in the middle Red is on the bottom There you go!
The top i think... Red. Yellow. Green.
To help people with colorblindness the "green" light has a mixture of green and blue. I think they the new lights have more blue than the older ones.
Green, followed by yellow, followed by red.
is just a symbol to show you when to go on and when to stop. usually the sequence of traffic signal light is red--NO cross; Yellow --warning; Green --cross. The three colors appear in turns.
It is usually on the bottom of the traffic light.
bottom
In North America, it's on the bottom.
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.
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.
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.
