Traffic signs are generally based on the Vienna Convention on Road Signs and Signals or on the United States Manual on Uniform Traffic Control Devices. This article is a summary of traffic signs used in each country.

Africa Generally, road signs in African countries closely follow those used in Europe, but most African countries have not ratified the Vienna Convention on Road Signs and Signals.

Although the Trans-African Highway network exists, Trans-African route numbers are not signed at all in any African country, except Kenya and Uganda where the Mombasa–Nairobi–Kampala–Fort Portal section (or the Kampala–Kigali feeder road) of Trans-African Highway 8 is sometimes referred to as the "Trans-Africa Highway".

A number of member states of the Southern African Development Community – Botswana, Eswatini, Lesotho, Malawi, Mozambique, Namibia, South Africa, Tanzania, Zambia and Zimbabwe, as well as non-member state Rwanda – use road signs which are based on the SADC Road Traffic Signs Manual, a document designed to harmonise traffic signs in these countries. However, not all member states have adopted the SADC-RTSM, and those that have may not use all signs listed in the SADC-RTSM or may use regional variations.

Member states of the Economic and Monetary Community of Central Africa – Cameroon, the Central African Republic, Chad, Equatorial Guinea, the Republic of the Congo and Gabon – use a signage system based heavily on that of France.

Angola

Road signs in Angola are particularly modelled on the Portuguese road signs since Angola is a former Portuguese colony. Since the country is a member of the Southern African Development Community, road signs are going to be harmonised with the traffic signs in member states of the Community according to the SADC Road Traffic Signs Manual despite they are transitional in nature.

Burundi Road signs in Burundi are similar in appearance to those used in Italy with certain distinctions. They are written in French in uppercase letters.

Djibouti Road signs in Djibouti are similar in appearance to those used in Spain with certain distinctions. They are written in French in uppercase letters.

Egypt Road signs in Egypt are regulated under the Egypt Traffic Signs Manual (ETSM). They closely follow those used in the United Kingdom with certain distinctions. They are written in Arabic and English.

Mauritius

Road signs in Mauritius are regulated by the Traffic Signs Regulations 1990. They are largely derived from the British road sign system since Mauritius is a former British colony.

Morocco

Nigeria Road signs in Nigeria do not differ greatly from those used in the rest of the African continent. However, it notably makes use of a yellow background for warning and prohibitory signs, as well as yellow text for the stop sign.

Sierra Leone Road signs in Sierra Leone are similar in appearance to those used in Italy with certain distinctions. They are written in English in uppercase letters.

Somalia Road signs in Somalia are similar in appearance to those used in Italy with certain distinctions. They are written in Arabic and Somali.

Uganda

Road signs in Uganda are largely derived from the British road sign system since the country is a former British colony.

Asia Road signs in Asia differ by country. Typically, Asian countries closely follow Europe in terms of road sign design, which means they are influenced by the Vienna Convention on Road Signs and Signals, though a number of countries' signage has been influenced from the Manual on Uniform Traffic Control Devices (MUTCD), for example Cambodia, Japan, Thailand, Myanmar, Sri Lanka, Malaysia and Indonesia.

Asian Highway Network signs are marked using white letters on a dark blue background. In Turkey and Russia, European route numbers are indicated using white characters on a green rectangle and are signposted; however this is not the case in many other Asian countries.

Armenia

Road signs in Armenia are similar in design to those used in the Soviet Union before its collapse in 1991 as the country was a Soviet Socialist Republic until 1991. Modern road signs used in Armenia generally maintain the same design as those used in Russia, with the exception that inscriptions on road signs are written in both Armenian and English, including the stop sign.

Azerbaijan Road signs in Azerbaijan are similar in design to those used in the Soviet Union before its collapse in 1991 as the country was a Soviet Socialist Republic until 1991.

Bangladesh

Cambodia

In Cambodia, road signs are prescribed by the Ministry of Public Works and Transport. Cambodian road signage practice closely follows those used in Europe — with the exception of warning signs which follow the American MUTCD — matching these designs used in other Asian countries like Japan, Myanmar, Thailand, Malaysia and Indonesia.

China A variety of road signs are used in mainland China, specified in the Guobiao standard GB 5678–2009. Most road signs in China, like warning signs, appear to adopt the practices of the ISO standards not intended for use in traffic signage, which are ISO 3864 and ISO 7010. Warning signs in China are triangular with a black border, yellow background and black symbol. Mandatory signs generally follow European conventions (circular with red border/blue circle) with some local variations. Direction signs have these colours: Green for expressways Brown for tourist attractions Blue for other roads Occasionally, black on white is used for directions to local facilities.

Hong Kong

Hong Kong's traffic signs are derived from the British road sign system, and are bilingual in English and Chinese (English on top, and traditional Chinese characters at the bottom).

Macau

Road signs in Macau are inherited from Portuguese road signage system prior to 1994/1998. Inscriptions are written in Chinese (traditional Chinese characters) and Portuguese.

Taiwan Road signs in Taiwan are reminiscent of the early 1940s Japanese road signage, which was used in Japan itself until 1950. Overall, Taiwan is lenient towards European road signs in terms of design, but with some influences from road signs used in Japan and China, as well as the MUTCD for guide signs and temporary signs (amber rhombic warning signs).

Georgia

Road signs in Georgia are mostly inherited from those used in the former Soviet Union, but with some modifications in design. Inscriptions on road signs are usually written in Georgian and English.

India

Road signs in the Republic of India are similar to those used in some parts of the United Kingdom, except that they are multilingual. Most urban roads and state highways have signs in the state language and English. National highways have signs in the state language and English.

Indonesia

Iran

Road signs in Iran mainly follow the Vienna Convention. Text is written in Persian and English.

Iraq Road signs in Iraq are regulated in Chapter 11 of the Highway Geometric Design Code. They are written in Arabic and English.

Israel

Road signs in Israel mainly follow the Vienna Convention, but have some variants. Many signs are trilingual, with text written in Hebrew, Arabic and English.

Japan

Road signs in Japan are either controlled by local police authorities under or by other road-controlling entities including Ministry of Land, Infrastructure, Transport and Tourism, local municipalities, NEXCO (companies controlling expressways), under . Most of the design of the road signs in Japan are similar to the signs on the Vienna Convention, except for some significant variances, such as stop sign with a red downward triangle.

Kazakhstan

The design of road signs in Kazakhstan is largely based on that of the former Soviet Union. Inscriptions on road signs, including the names of settlements and streets, are usually written in two languages: Kazakh and Russian.

Korea

Both North Korea and South Korea developed their own road signage systems.

Road signs in South Korea are standardised and regulated by the Korean Road Traffic Authority. South Korean road signage closely follows those used in Europe, but with some influences from road signs in Japan. Similar to road signs of Poland and Greece, road signs are triangular, have a yellow background and a red border. Like other countries, the signs use pictograms to display their meaning.

Road signs in North Korea differ by locale. Most of the time, they tend to closely follow China in design (but identically), and some road signs are unique to North Korea (such as an exclamation mark drawn on another sign to indicate other dangers), so they never appear elsewhere. The font used for Latin letters appear to be the same as in China.

South Korea keeps close to the Vienna Convention on Road Signs and Signals as South Korea is an original signatory. On the other hand, North Korea is not a signatory to the convention and instead designs its own signs, creating confusion.

Kuwait

Kyrgyzstan

The design of road signs in Kyrgyzstan is largely based on that of the former Soviet Union.

Laos

Malaysia

Mongolia

The design of road signs in Mongolia is largely based on that of the former Soviet Union, despite having never been part of it. Inscriptions on road signs are usually written in Mongolian and English.

Myanmar

Nepal

Oman

According to the 2017 Highway Design Standards, road signs in Oman follow the standards set out in the Gulf Cooperation Council's Manual on Uniform Traffic Control Devices.

Pakistan

Philippines

Road signs in the Philippines are standardized in the Road Signs and Pavement Markings Manual, published by the Department of Public Works and Highways. Philippine road signage practice closely follow those used in Europe, but with local adaptations and some minor influences from the US MUTCD and Australian road signs. However, some road signs may differ by locale, and mostly diverge from the national standard. For example, the Metropolitan Manila Development Authority (MMDA) has used pink and light blue in its signage for which it has been heavily criticised.

Regulatory road signs are generally circular, and most warning signs take the form of a triangle. Since 2012, however, a more visibly distinctive design (taken from that used for school signs in the US) has been adopted for pedestrian-related signs: these consist of a fluorescent yellow-green pentagon with black border and symbol.

The Philippines signed the Vienna Convention on Road Signs and Signals on 8 November 1968, and ratified it on 27 December 1973.

Qatar

Road signs in Qatar are regulated under the Qatar Traffic Control Manual (QTCM). They closely follow those used in the United Kingdom with certain distinctions. They are written in Arabic and English.

Russia

Road signs in the Asian part of Russia follow the Vienna Convention, specified in the GOST standard 52290-2004 (the Soviet Union was an original signatory to the convention, but only a few post-Soviet states are signatories to the convention). However, direction signs in the Asian part of Russia omit European route numbers (which are used in the European part), replaced by Asian route numbers, which are dark blue in background with white lettering, with a few exceptions. The same also applies to road signs used in Central Asian countries such as Kazakhstan, Kyrgyzstan, Tajikistan, Turkmenistan and Uzbekistan.

Russia signed the Vienna Convention on Road Signs and Signals on 8 November 1968 and ratified it on 7 June 1974.

Saudi Arabia

Road signs in Saudi Arabia are generally written in Arabic and English. A particular aspect of Saudi signage is that they indicate areas which are forbidden to non-Muslims in the cities of Mecca and Medina.Saudi highway signs near Makkah (archived)
