Daniel GibertI just made this silly but accurate thing. I'm silly too and i love it, but also i'm serious in my silliness.
Simon@danielgibert I love it. But I believe in this case it's not 'european', it's 'literally every country except that single stupid one we don't talk about'
njsg@realsimon @danielgibert My guess is that it's (at least) all countries that have signed to the Vienna Convention. Also, the background of the right side ones can be yellow.
Greg Pfeil@njsg But can the banana be yellow?
Nishcott@sellout Only the left ones can be! If it's blue, it's yellow; if it's red, it's green.
Gregory@njsg @realsimon @danielgibert the yellow background means that this sign is temporary and has priority over the white-background ones
SchwarzeLocke@grishka @njsg @realsimon @danielgibert oh, just like on the ground, where the yellow lines are temporary overruling the white lines, here in Germany.
Júbilo MX (moved to @@SchwarzeLocke @grishka @njsg @realsimon @danielgibert the three Countries in North America 🇲🇽 🇨🇦 🇺🇸 need the red diagonal in the restrictive ones... and at least in Canada the obligatory/allow one has a green circle (haven't drive enough in the US to confirm that) and that's not a thing in Mexico

jack@buzzyrobin @realsimon @danielgibert fond memories of trundling along the Bass Highway and spotting a sign which said, in all caps, something like
"LANE MARKINGS REMOVED DO NOT OVERTAKE UNLESS IT IS SAFE TO DO SO"
which was to me a breathtaking statement of the bloody obvious, and completely oblivious to the average driver's reading comprehension while travelling at highway speed
Thomas Lumley@jackeric @buzzyrobin @realsimon @danielgibert my favorite old Aus road signs were the ones saying "Loose Stones Travel Slowly", which would make a good meaningless proverb

Blackcap@realsimon @danielgibert Not to mention Canada and Mexico and how most of South America is a mix of MUTCD and Vienna Convention style signs. https://en.wikipedia.org/wiki/Comparison_of_MUTCD-influenced_traffic_signs
1000millimeter@blackcap @realsimon @danielgibert IT ISN'T EVEN THE SAME THROUGHOUT THE US?
I wasn't aware if this.
(And funny, just entered Denmark via train, saw road signs next to the tracks, and thought it's interesting they are all similar in other countries. Just a few minutes after, I saw this thread and learned about vienna convention.)
@1000millimeter @realsimon @danielgibert It's pretty darn similar throughout the USA, though different states do have variant signs. But it's subtle differences. They all look very MUTCD-like. You would in no way mistake the signage in any US state for Europe.
The Lack ThereofYeah that's because we standardized back in 1920's, and what we standardized ON was basically whatever guerilla signage various auto clubs had been putting was most popular in the 1910’s
We tried adopting Vienna Convention signage in the 1970's but the trial was an unmitigated disaster, so instead we settled for slowly updating the MUTCD to start replacing text on signs with symbols. The only remaining vestiges of the attempt are a handful of rare signs with metric units.
Jeff GriggWe wouldn't because no one would put a banana up next to the sign for a size comparison! No we could understand those "kilos" of "meters" or whatever! 😢
@JeffGrigg @realsimon @danielgibert kilometer is just kilogram of meters. Idk why it's hard to understand 🤔
Scam Likelyhi! lots of countries don't use the vienna convention! canada, essentially all of latin america and the caribbean, australia and NZ, southern africa, among others.
just because the united states does something doesn't mean it's wrong, and also doesn't mean it's the only country on the planet that does it.
@vorboyvo excuse my ignorance. I was unaware that there are multiple countries that use wrong street signs.
Iris Young (he/they/she) (PhD)@danielgibert this is great and I appreciate it for both its informational and its entertainment value.
Gabriel Pettier@danielgibert that's great actually.
Talya (she/her) 🏳️⚧️✡️@danielgibert interesting, the blue square doesn't seem to exist in my country! we mostly just do the forbidden one in black and white and cross it with a thick black line (yeah i know it technically means end of forbidden zone but i just don't think we have "allowed to do x" zones).
@danielgibert okay i checked the wiki page for the local traffic signs in my country and we do have a blue square but used differently, generally it's like a less severe warning. so like change in the number of lanes, mixed use zone, parking, disabled parking etc. are all blue square.
@Yuvalne yep. Same as here. Blue square for things you can do but are not mandated to.
@danielgibert
i don't know if it entirely fits the definition, at least not in my country. "lanes merging" is something you do have to deal with eventually. "dead end road" too.
idk maybe i'm just being too pedantic

Janne Moren@Yuvalne @danielgibert
It tells you what you can do - what your options are.
A one-way street marker is a blue square with an arrow telling you the direction you can go. There is only one direction so not much to choose from - but it's still telling you the allowed behavior. It's a positive sign.
But then it's often combined with a red entrance forbidden sign for the other direction, telling you what you *can't* do. It's a negative sign.
@jannem @danielgibert
a "positive sign that tells you what your options are" also includes this one though.

@jannem @danielgibert
and on the other hand, this one isn't "you may give right of way to pedestrians" but "you must".

@[email protected] @[email protected] @[email protected] yeah i know. i'm just saying that the blue square and blue circle aren't exactly consistent categories.
Erwan 🚄@Yuvalne @jannem @danielgibert It is information you are arriving to a pedestrian crossing, however (in France at least) you must always give way to pedestrians, even without this sign
Talya (she/her) 🏳️⚧️✡️ (@[email protected])
@[email protected] @[email protected] @[email protected] so it's not a "you may", it's an "FYI"!!
Helle, Queen of Dissociation 
@Yuvalne @jannem @danielgibert "you must go straight or right" used instead of "you cannot go left" in a few countries as permissive signs are easier to read
@helle @jannem @danielgibert
again i know what the sign means and when it's used (usually my country puts a "left turn forbidden" when one would assume it'll be allowed".
but "one way" is also a "you must" thing. it's not a recommended speed, you can't decide you're not gonna do it.
same for this little fellow:

@Yuvalne @jannem @danielgibert one way actually isn't a must thing, it is just to inform you that there is no traffic from the other direction, if you leave it out, it doesn't change what people can and cannot do (presuming no special maneuvers like making a u turn in the street)

@Yuvalne @jannem @danielgibert at least in dutch law, the signs are informative, the markings on the road surface for pedestrian crossing are the legally binding part
@Yuvalne @jannem @danielgibert and yes, I am being incredibly pedantic, I also actually like the logical approach to the signs
there is one exception here btw "woonerf" is legally binding here and by a square sign, not just informing you (the road looking like one is not enough)

I hate it
@helle @jannem @danielgibert
my point being dividing all blue signs into "you may" and "you must" isn't an obvious clear cut. it's more "that's the way the junction behaves here, follow the rules accordingly" (traffic circle, junction with permitted turns, etc.) +"the type of people allowed here" (pedestrian way, bike lane etc.) for circles vs "you're entering the following area, follow the rules accordingly" (pedestrian right of way, mixed use zone, toll road etc.) + general "FYI"s for squares

@Yuvalne @helle @danielgibert
The confusion stems, I think, from these signs being blue; but informational signs - distance and direction to various towns and so on - are also blue background with white text (because it's the easiest to see).
But overall see them as "these are your options for things you can do", where, sometimes, there's only one option.
@jannem @Yuvalne @danielgibert the intent of the system is that only round blue signs contain legally binding instructions, but sometimes this doesn't seem true (one way entry and pedestrian crossing sign) and sometimes literally isn't true (living street "woonerf" sign, built up area name sign in The Netherlands)
@helle @jannem @danielgibert
okay so i did the nerdiest thing and opened the Vienna Convention.
signs are defined to have the following categories:
(a) Danger warning signs;
(b) Regulatory signs; sub-divided into:
(i) Priority signs;
(ii) Prohibitory or restrictive signs; and
(iii) Mandatory signs;
(iv) Special regulation signs.
c) Informative signs; subdivided into:
(i) Information, facilities or service signs;
(ii) Direction, position or indication signs;
(iii) Additional panels

@helle @jannem @danielgibert
however, it seems there's only nine examples of blue background signs (some article B and some C) in the convention, and that "city that way" and "yellow warming square" also fall under the same articles.

@helle @jannem @danielgibert
and by the way, "one way" is in a different category of "special regulatory sign", together with "road for motor vehicles" (which is a circle!)

Oto Šťáva@Yuvalne @helle @jannem @danielgibert Huh, "road for motor vehicles" is a square in my country, interesting!
@Yuvalne @helle @jannem @danielgibert Interestingly enough, blue signs seem to be mostly consistent here, unless it's on a path that is only meant for pedestrians and/or cyclists.
https://en.wikipedia.org/wiki/Road_signs_in_the_Czech_Republic
(I've also never seen the blue circular lorry sign, they generally use the prohibitive one instead.)
@alefunguju @helle @jannem @danielgibert oh interesting, your express way sign is green! ours is blue.
@Yuvalne @helle @jannem @danielgibert But yeah, bicycle and pedestrian zones are circle here as well. I stand corrected.
@Yuvalne @helle @danielgibert
I think my point (such as it is) is mostly the contrast with the negative "may not" of red-border signs.

yeah, it's less the circles that are a problem and more the squares, those are less definite.

@Yuvalne @helle @jannem @danielgibert technically that one only exists to inform you that there's a pedestrian crossing, the crossing itself as painted on the ground is what tells drivers they have to give pedestrians right of way
At least that's what I understood from when I learned to drive and from browsing my grandfather's driving books as a kid
