It also specifies the symbols and pictograms that may be used, as well as the orientations in which they may be used. If there are several, it should be used at the national level. All signs, except those that do not apply at night, must be reflective enough to be seen from afar in the dark with spotlights. The Convention on Road Signs and Signals, commonly known as the Vienna Convention on Road Signs and Signals, is a multilateral treaty aimed at improving road safety and supporting international road traffic by standardizing the system of road traffic signs used internationally (road signs, traffic lights and road markings). This Convention was adopted by the United Nations Economic and Social Council at its Conference on Road Transport from 7 to 8 October. November 1968 in Vienna, closed on 8 November 1968 in Vienna and entered into force on 6 June 1978. This conference also gave rise to the Vienna Convention on Road Transport, which complements this legislation by harmonizing international road traffic law. The only countries in Asia that are not parties to the Convention are Bangladesh, Myanmar, Malaysia, the Republic of China (Taiwan), the People`s Republic of China (including Hong Kong and Macao), Japan, Israel, Palestine, Saudi Arabia, Jordan, Lebanon, Syria, Armenia, Yemen, Oman, North Korea and Afghanistan.

Red flashing lights may only be used in the above places; Any other use of the luminaires violates the convention. Red lights shall be placed at the top when the lights are stacked vertically or on the side closest to oncoming traffic when stacked horizontally. Other countries have not signed the Convention, but they have voluntarily adopted some of these signs of the Vienna Convention. Although most UN members have not ratified the full treaty, the signs and legal principles enshrined in it form the basis of the rules of the road in most places. In August 2016, the Convention affected 68 States Parties: Albania, Austria, Bahrain, Belarus, Belgium, Bosnia and Herzegovina, Bulgaria, Central African Republic, Chile, Côte d`Ivoire, Croatia, Cuba, Cyprus, Czech Republic, Democratic Republic of the Congo, Denmark, Estonia, Finland, France, Georgia, Germany, Greece, Hungary, India, Iran, Iraq, Italy, Kazakhstan, Kuwait, Kyrgyzstan, Latvia, Liberia, Lithuania, Luxembourg, North Macedonia, Moldova, Mongolia, Montenegro, Morocco, Netherlands, Nigeria, Norway, Pakistan, Paraguay, Philippines, Poland, Portugal, Romania, Russia, San Marino, Senegal, Serbia, Seychelles, Sierra Leone, Slovakia, Slovenia, Sri Lanka, Suriname, Sweden, Switzerland, Tajikistan, Tunisia, Turkmenistan, Turkey, Ukraine, United Arab Emirates, Uzbekistan and Vietnam. The Vienna Convention and the Geneva Protocol were formed after the consensus on road signs and signals, which developed mainly in continental Western Europe in the 20th century. To make it as universal as possible, the convention allows for some variations, for example, hazard warning signs may be triangular or square diamond-shaped, and road markings may be white or yellow. The length and width of the markings vary depending on the lens, although no exact number of the size is given; Roads in built-up areas should use a broken line for road sharing, while continuous roads can only be used in special cases such as restricted visibility or narrowed roads.
In Article 2, the Convention classifies all road signs into a number of categories (A – H): An alternative convention called SADC-RTSM, provided by the Southern African Development Community, is used by ten Southern African countries. Many of the rules and principles of SADC-RTSM are similar to those of the Vienna Convention. The Convention revised and significantly expanded the former 1949 Geneva Protocol on Road Signs and Signals, which in turn was based on the 1931 Geneva Convention on the Unification of Traffic Lights. The convention then defines precise colors, sizes and shapes for each of these character classes: Nehru Yuva Kendra Sangathan (NYKS) invites eligible candidates to apply online for 160 District Youth Coordinator (DYC) positions. .
