Base information

Traffic signs and signals are displayed here supported by quite a few GIF images (the signals are animated).

Note: work is still very much in progress!

Online sources

International treaties are from the Swiss law site which is very complete, but it is only in French, German and Italian. Their PFD is not very good, and their HTML does not cover the actual signs at all, but still the most complete site to be found.

International

1926 French | German | Italian
The first convention where something was done about the differences in traffic signs across the nations. No actual signs are given.
1931 French | German | Italian
This convention was actually about traffic signs. The documents above, alas, do not include the actual signs, but I think they can be ascertained from the text.
1949 In 1949 there has been a convention in Geneva that covered (amongst others) international traffic signs. As far as I have been able to ascertain this just prolonged and perhaps extended the 1931 convention.
1968 French | German | Italian
The Vienna convention on (amongst others) traffic signs. This convention is shown complete, including the actual signs, but this is the version after the amendments of 1993.
1971 French | German | Italian
Additional European rules about traffic signs.
1973 French | German | Italian
Additional European rules about road markings.
1993 No source yet
In 1993 the Vienna convention was amended, I am still researching whether there were fundamental changes.

Western Europe

Andorra Presumably uses Spanish type signs.
Austria German, unofficial | German, unofficial
These are sites of manufacturers of traffic signs, they contain slightly different pieces of information.
Belgium Dutch | French
The complete law, well done, I am missing the German version. Otherwise it is official; done by the Belgian police.
Danmark Danish, unofficial
This is the site of a manufacturer of traffic signs.
Finland English | Finnish
The English version does not give you the road marks. I do not know the actual status of this site, but it appears to be fairly official.
France French, unofficial | French, unofficial | French, unofficial
A reasonable collection of French traffic signs, the first from a person, the second from a company (a bit more complete, but apparently Windows oriented), the third apparently shows old fashioned traffic signs, but is fairly complete.
Germany German
The complete law, well done. By what I understand this site maintains the online versions of German law.
Greece Greek
This gives the law, the second link on this page will give a page with links to pages with traffic signs. It is incomplete.
Iceland Icelandic
A well done exhibition of the traffic signs, otherwise I do not know what the status of this site is, but it appears to be fairly official.
Ireland English, unofficial
Contains a set of Irish traffic signs, probably incomplete. I do not know whether it is even possible to get a complete set of valid traffic signs.
Italy Italian, unofficial
A site designed to learn you the rules. Bad images, but otherwise well-done (but it takes some time). You better buy their CD-ROM version.
Liechtenstein Presumably uses Swiss type signs.
Luxembourg Nothing found yet.
Malta Nothing found yet.
Monaco Presumably uses French type signs.
Netherlands Dutch, unofficial
An excellent exhibition of traffic signs. The law is also there.
Norway Nothing found yet.
Portugal Portuguese | Portuguese
Both from the Portuguese directorate for traffic. The first one gives the rules, the second one the signs. The signs you will find in a zipped archive containing pdf'ed scans of the pages (two pages are missing), when you have gone through all the text.
San Marino Presumably uses Italian type signs.
Spain English | Spanish | unofficial
The last one shows pictures but does not give explanations, the first two give only the rules and are from the Spanish directorate for traffic.
Sweden Swedish
Excellent traffic sign reproductions. I could not find the rules there. This is the Swedish government institute for road traffic.
Switzerland German | French | Italian
There is something wrong with their PDF, but it gives all rules, the HTML version gives the rules but a horrible display of the signs.
United Kingdom Nothing found yet. I used paper sources for all information.

Eastern Europe

Belarus Belarus
The complete law plus traffic signs; in Belarus I think, but it can also be Russian. I think the traffic signs are as they were in the Soviet Union (considering the standards mentioned in the text: GOST 10807-78 and 23457-86).
Czech Republic Czech, unofficial
Incomplete, and no description of the actual meaning.
Estonia Estonian, unofficial
Complete rules and set of signals (see at the bottom of the menu, lista 1 and following).
Hungary Hungarian
The complete law, alas in Hungarian. The pictures leave something to be desired.
Latvia Russian
The law, in Russian. I think this is the Russian law and do not know whether Latvian law is different at this moment (I think it is not). See also Belarus.
Poland Polish
The complete set is presented here.
Rumania Rumanian | Rumanian, unofficial
The first gives the law, the second (from presumably unofficial source) a set of traffic signs. I think the set is incomplete.
Russia Russian
The law, no signs here. See also Belarus.
Turkey Turkish | Turkish, unofficial | Turkish, unofficial
The first one is from the government, but incomplete. The second one is the most comprehensive, but not official.

Africa

South Africa English | English, unofficial | English, unofficial
The first is the government which gives the regulations, the other two are companies. The first company site is apparently in progress to show all, but not yet done with it; the second company only gives a subset. Apparently the traffic signs are valid for a large part of Southern Africa, namely the following countries: South Africa, Swaziland, Lesotho, Namibia, Angola, Botswana, Zimbabwe, Zambia, The Democratic Republic of Congo, Malawi, Mozambique, Tanzania, Seychelles and Mauritius (together called the SADC).

Asia

China Chinese | Chinese
The colours appear not to be well defined here, and the HTML is not entirely correct, but it is the government.
Hong Kong Chinese | English
The complete road rules, including all signs.
India English and Hindi | English, unofficial | English, unofficial
From a police site, not complete I think. The second is from a company and has signs not in the first. The third is from industry and better detailed.
Japan English | English
Two police prefectures, these two are both incomplete, they are overlapping, but not identical.
Korea (North) English and Korean, unofficial
It appears reasonably complete.
Malaysia English and Malay
Apparently all signs.
Taiwan Chinese, unofficial | Chinese, unofficial
A company and a school, for some of the signs I do not yet know what they mean. Click on any link provided and you will get further.

Pacific

Australia English | English | English | English | English | English | English
The first is a pointer to the road rules from Victoria (there are other places where they can be obtained). They do only give the regulatory signs, no others. The other links give some information about warning signs; none is complete, although there is some overlap.

North America

Canada French | English | French | English | English | English | English | English/French
All are incomplete, but not identical. The first two are from the Ontario government, the others from the Quebec, two from Alberta (the first is pdf, the second html), Nova Scotia and British Columbia (this one is complete in pdf, check the link "traffic sign catalogue") governments, the last one is from a company.
USA English | English, unofficial
The new offical year 2000 manual of traffic signs in the USA, and an unofficial, but complete current listing.

Brazil Portuguese
Apparently complete.
