We have different shapes in The Netherlands.

this signs mean you are on a major road, and all other directions have to let you pass first.

this sign explains the situation with intersections. Here, you are allowed to go first. This sign is used, when not a whole ****** is a priority road. (when a sign like the first one is used).

this one means you have to give way to other drives on the intersectioning road.

These shapes are used, so even when it snows, and the sign is covered with snow, you still know the meaning of it.

Yes in most of europe it's like that, but this is only about the warning ones (the one in the middle).

For me it doesn't matter if warning signs will be triangular or diamond as long as they provide clear information, consistent with each other and have pictures instead of the text.

There is really no difference between:

and

and

and

However, warning signs that only have text are extremely inefficient because you can read the message only if you are close enough (50 metres). This really defeats the whole purpose of a warning sign.

In the U.S. they usually make diamond signs larger on large highways so you can read them better.

It all depends...
If you are a European it's unfamiliar for you when you are driving in countries like Canada or USA and the other way round.
Well you can't say that the triangle is better or worse than the diamond. For me of course the diamond is worse because I am used to see the triangle ones.
But I doubt that warning signs with too much text or only with text are better than the European ones where most the time simple symbols are used.

But why not to use pictorial signs? It is a widely accepted fact that human beings tend to memorise pictorial form of information better than textual. What I mean is that no matter if the population is monolingual or not, pictures are still more efficient than text.

To be different from Britain? But seriosuly, even though they use yellow diamonds, the pictures on them are still much closer to Britih ones than American ones. In America, for instance, you would never find this sign, yet it is very common on European triangular signs:



Plus, Irish signs distinguish between intersection with minor road and major road - a useful feature that is not introduced in the US. Canada has them though:

I have always wondered about this. In Canada, like in all countries that drive on the right, the rule is to let the vehicle on the right go first if no signs are present. However, it is quite confusing because in Canada (and I assume most of North America) they never tell you if you are on a major road or not. This creates a situation where if you approach an intersection and you do not see any signs, you have to first look carefully to the side and see whether the crossing road has stop signs or yield signs. This is quite stupid and in my opinion should not be the responsibility of the driver of the main road. In practice, this is the case pretty much 100% of the time, so on most small residential streets one just passes such an intersection without looking anywhere. In reality, in my opinion, if the cross road has a yield/stop sign, the other road should always have a sign telling the driver that he has the right of way. Otherwise, the "priority to the right" rule is sort of pointless, even though I am yet to actually encounter an intersection in Canada where this rule would be applied (maybe on remote rural roads?)

Exactly! And all it takes is to implement a warning sign like or It really doesn't take a lot of effort to start putting these warning signs neither in terms of funds nor in changing the existing traffic rules.

The principle of main and secondary roads would even work better, but I wonder if it would be too complicated for an average American driver.

I remember in a design class that (at least in North America) the number of sides a sign has is proportional to the severity of the inforamation being displayed by the sign. Thus, a triangular yield sign bears a passing caution while an octagonal stop sign commands your full attention. This warning is also extending to packaging warnings about flammability, corrossiveness and explosions on various products with the severity going from triangle to diamond to octagon.

Diamond warning signs are used as in a cautionary sense. The pentagonal school crossing signs express heightened caution to drivers due to the number of children in the area. At this point the only round (1-sided) signs I have seen are for road designations and serve no warning/cautionary purpose, just informational. The old round railway crossing signs have since been replaced with the 12-sided X sign along with the flashing red lights.

What about "Yield" sign? It has a tringular shape, yet it is as important as the STOP sign.

As for the warning signs, European triangular ones bear exactly the same significance as the American diamond ones. No difference whatsoever.

But "Give Way" ones are upside down.

I think purely from a design point of view yellow diamonds are superior, because they create a clear distinction from the regulation signs (which tend to be a white circle with a red outline) and because they give more space to display larger, and therefore more easy to read pictograms.

You could ask why Ireland uses them, as it is exceptional as a European country in doing so, but equally the UK seems to be the only one which uses red diamonds out of the english-speaking countries.
