Advidana,
That has to be the most rediculous thing I have every heard.
You got hit going through a green light... poor you ... bad luck... that is all... it still does not diminish the intent of the lights...as with any logic system the system is only as good as the users...

Just to muddy the waters, there is really no universal standard for this, not even a US standard, at least in practice. It's just a convention.
In the utility industry in the US, the use of red for energized and green for de-energized is nearly universal in transmission and distribution systems. In power plants, this usage is continued by using red for running motor and red for open valve.
But in other industries, it's often exactly the opposite. Many water and wastewater plants use green for ON and red for OFF. I've even some it done both ways in the same plant on different panels. Drives me nuts.
The world would be a much better place if everyone used RED for ENERGIZED, just as the Creator intended.

The beer is still in the middle of the table and getting warm.
Really, no one here has a definitive answer?
The two contenders in this thread, IMHO, are:
A COMBINATION OF: Tommy75 with the Navy SOP explanation and
DPC with the "it's only a convention"
===OR===
The fable of "How Corporate Policy is Made"
Start with a cage containing five monkeys. Inside the cage, hang a banana on a string and place a set of stairs under it. Before long, a monkey will go to the stairs and start to climb towards the banana. As soon as he touches the stairs, spray all of the other monkeys with cold water. After a while, another monkey makes an attempt with the same result; all the other monkeys are sprayed with cold water.
Pretty soon, when another monkey tries to climb the stairs, the other monkeys will try to prevent it. Now, put away the cold water. Remove one monkey from the cage and replace it with a new one. The new monkey sees the banana and wants to climb the stairs. To his surprise and horror, all of the other monkeys attack him. After another attempt and attack, he knows that if he tries to climb the stairs, he will be assaulted.
Next, remove another of the original five monkeys and replace it with a new one. The newcomer goes to the stairs and is attacked. The previous newcomer takes part in the punishment with enthusiasm! Likewise, replace a third original monkey with a new one, then a fourth, then the fifth. Every time the newest monkey takes to the stairs, he is attacked. Most of the monkeys that are beating him have no idea why they are not permitted to climb the stairs or why they are participating in the beating of the newest monkey.
After replacing all of the original monkeys, none of the remaining monkeys have ever been sprayed with cold water. Nevertheless, no monkey every again approaches the stairs to try for the banana.
Why not?
Because as far as they know that’s the way it’s always been done around here.
