Why on a stop light is the red at the top and green at the bottom?

Question

Why is green not at the top and red at the bottom? Who decided to design them this way?

Answer 1

Red's more important than green. Your more likely to cause an accident running a red light than stopping at a green.

Once a standard is set, it is followed so that color-blind people know from the position which light is lit. They can't tell red from green.

Answer 2

It's pretty much a standard thing, so maybe the red being on top makes it more visible at a greater distance. So if there is a tall vehicle in front of you, you will know to stop. As where the green light mainly needs to be seen by the front vehicle to get every body going,

Edited: go down two answers to "n K", he has the answer!!

Answer 3

I've heard in Ireland green is at the top. It's standardized so those of us that are red green color blind know what to do, and the standard just happened to call for red on top.

Answer 4

There are human beings like my son, seriously pink eco-friendly coloration blind. If lights fixtures weren't standardized, and each and every jurisdiction might want to do as they overjoyed, it might want to be chaos for those human beings. initially there have been no longer that many automobiles or roads, as they more effective and bigger roads were made, end signs and indicators, and later site visitors alerts got here into being, taking their cue specially from the railroads, pink became prevalent on proper, and now the coloration blind human beings did no longer ought to agonize. proper gentle lit, end. bottom gentle lit, even with the very incontrovertible certainty that it truly is an identical coloration (to them) go.

Answer 5

It's not standard, you nimrods. There are lots of signals that are sideways. Red on the left, green on the right. Drive east on Orangethorpe Avenue in Placentia, California and go under the 57 freeway and you will see some of them.

Answer 6

Not necessarily so- the lights in some municipalities are lain down in a horizontal position (the red light being the inward signal).

Answer 7

I think to make drivers able to see it from distances. (the red lights are more important than the green lights)

Answer 8

thats just how it is. if you go to other states, like texas, the lights are set sideways. red on the left and green on the right.

Answer 9

So the color blind have a standard! Bottom light is OK to go!

30% of ALL men on the planet are color blind!!!
