If the page is to be reorganized, can I suggest mention of the following, from France:
Traffic signals are never repeated at the other side of the intersection in France. Drivers in most parts of the world (Ireland, UK, USA, Australia - my experience only) who are first in the queue at a red light are used to being able to look across the intersection and seeing the light that applies to them displayed. This is not the case in France.
Why do they do this? It does make absolutely clear the point at which a driver must stop. It also removes any confusion that can occur at oddly shaped junctions where some drivers look at the wrong light.
It also removes the following problem: at some T-junctions in UK, I have seen drivers coming from the minor road onto the through-road and stopping because they see the red-light meant for drivers on the through-road. They are incorrect in doing this but would be correct if in France.
It is also useful in towns and cities where there are several junctions spaced close together.
It has disadvantages though: if turning left in France and you move into the junction waiting for a gap in the traffic to turn, you have no way of knowing when the green changes to amber and red.
The same is true in heavy traffic. If you edge past the lights into the junction going straight on you don't know when the lights change.
The following help this situation:
1. A second set of traffic lights is always displayed at a lower level for the driver at the front of the queue. This solves one problem but it does mean that the driver is looking to the right before moving off. I much prefer looking straight ahead to see any potential hazards.
2. For left-turning traffic, there is sometimes a light displayed to indicate when traffic coming in the opposite direction has a red-light and thus when it is safe to turn. This light is in the form of a red cross. When lit, opposing traffic has red light. When not lit, opposing traffic has green light. David in dublin 15:06, 23 July 2007 (UTC)
The correct term is a Traffic Signal, not Traffic Light. This is because they provide a signal for drivers to obey rather than providing light for illumination (being able to see). The term written in UK law is Traffic Light Signal and they are also known as Automated Traffic Signals, the use of 'Traffic Light' is not technically correct and should be discouraged.

I just reverted this edit by Epicentre as I cannot follow its rationale. Firstly, by the lingo used in my area (so perhaps it's different elsewhere), a malfunction results in flashing amber; but a failure results in a dark signal. Secondly, if all sides are expected to give way, what would be the point of adding a stop sign? How would the approaches without the stop sign -- whom are not supposed to stop -- know that the other approaches have the stop sign? Is a sign provided which indicates that they may travel through without stop on flashing amber? Are varying colors used in each direction instead of signs, as in N.America where flashing amber indicates a vehicles may proceed with caution and flashing red indicates a vehicle must stop? And what happens if the signal is dark: do the duties of motorists change as compared with a flashing signal? If you can provide references, that may help in clearing up my confusion. Lastly: it is not advisable to mark information additions as minor edits. Cheers! -- Bossi () 11:13, 22 August 2007 (UTC)
Okay, so in Lloydminster I can be waiting at a red signal according to Alberta's traffic laws going one way and Saskatchewan's going the other way. Why is this relevant? If Alberta permitted right-on-red and Saskatchewan didn't, for example, I can see why it might make a difference. Merely talking about an issue of the jurisdiction in which any cases arising from any crashes might be heard, in one set of junctions in one town, seems a little irrelevant to a general article on traffic lights.

not sure if or how relevent itis so I thought I would at least bring it up here ... Traffic Signal Operations Specialist. looks intresting and somewhat relevent. anyone know more about this ? Exit2DOS2000 15:15, 21 September 2007 (UTC)
Under the section Turning signals and rules they mention: "In a fourth type, sometimes seen at intersections in Ontario and Quebec, Canada, there is no dedicated left-turn lamp per se. Instead, the normal green lamp flashes rapidly, indicating permission to go straight as well as make a left turn in front of opposing traffic, which is being held by a steady red lamp."
I would just like to note that it's not only in Ontario and Quebec. They also have "flashing green" in Halifax, Nova Scotia.
If the first traffic lights were in the U.K. how are 'modern' traffic lights a U.S. invention? Firstly the design of traffic lights has been in a constant state of flux since their invention in the England. By adding the weasel word 'modern' the author is trying to assert that anything prior to the particular U.S. example quoted is not 'modern'
Truly 'modern' computer controlled lights with radio telemetry for emergency vehicles are what I would call 'modern' not the author's antiquated American example.
I don't believe there is a US centric thing going on here. And it is a mistake to think that the first traffic lights were invented in England. Why would anyone think that? Gingermint (talk) 20:50, 25 October 2009 (UTC)
Should Yacker Trackers (traffic lights in classrooms that monitor noise) be mentioned in Section 11.1, "As a rating mechanism"? Nerdygeek101 (talk) 14:37, 26 April 2008 (UTC)
The two edits by LMB on April 26, 2008 seem to have removed a great deal of text. Are they acceptable? Nerdygeek101 (talk) 15:23, 27 April 2008 (UTC)
A lot of new over-roadway technologies are being introduced and implemented. Should there perhaps be a sub-section within Technology called 'Sensors' to expound upon these technologies? Or is it perhaps as yet irrelevant since an overwhelming number of sensors at intersections as yet are in-roadway, with the exception of the emergency override sensors as discussed later in the article?

In France, traffic lights can show flashing amber to all directions. This means "give way to traffic entering from the right" - in other words, what you would do if the lights were not there. This may be activated in some failure conditions, or, at least until the late 1980s, at night. Of course, the same rule also applies if the lights are completely out.
Is it still common practice to effectively put the lights into "fail" at night in France? I haven't seen it for a few years but then have not spent much time on the road in France at night recently - many such instances have been in fairly large towns. EmleyMoor (talk) 18:38, 11 May 2008 (UTC)
When traffic lights are put to "fail" (all flashing ambers), they usually have a small warning sign on the same pole indicating priority at the junction when the lights are not operational. One approach will have yield, the other will have the sign indicating minor road ahead. Sometimes, the priority-to-the-right sign is used and this is the rule that should be obeyed if no sign is present.
It's very sensible, and handy if the lights do break down. Is it a waste of signs though??
The article states, Houston, Texas has a unique system in which tickets for running the red light caught by the camera are a civil infraction rather than a criminal offense that appears on your driving record. I don't believe this can be described as unique anymore; in Washington state, red light camera violations result in a fine but do not appear on your driving record. 64.81.163.112 (talk) 03:23, 11 July 2008 (UTC)
Why have headings been put in the middle?

"Nevertheless, it is increasingly and disturbingly common in at least the U.S. to see drivers who do not yield in the absence of a dedicated signal, cutting off traffic that has right-of-way and is starting to head across the intersection."
This is in the middle of a long paragraph about ¼ of the way down the page (in "Turning signals and rules"), but doesn't seem very encyclopedic. I will add a "citation needed" tag to it, but it probably should be deleted. 76.21.8.213 (talk) 19:12, 20 July 2008 (UTC)
sorry I'm new here so I will not be able to give lots of comments but I also think it's way to long
I came to this article hoping to see some explanation for the lights I'm seeing on top of traffic lights more and more often. Neither my family nor I underst
