Introduction
The Vienna Convention on Road Signs and Signals (in English: Vienna Convention on Road Signs and Signals; in French: Convention de Vienne sur la signalisation routière), is a multilateral treaty designed to increase road safety and assist international road traffic by standardizing the signaling system for road traffic (road signs, traffic lights and road markings) in use internationally.
This convention was agreed upon by the United Nations Economic and Social Council at its Road Traffic Conference in Vienna from October 7 to November 8, 1968, and entered into force on June 6, 1978. This conference also established the Road Traffic Convention, which complements this legislation by standardizing international road safety laws.
The convention revised and substantially extended the previous 1949 Geneva Protocol on Road Signs and Signals, based in turn on the 1931 Geneva Convention on the Unification of Road Signs.[1][2] Some amendments were adopted in 2003 that included new provisions regarding the legibility of signs, priority at roundabouts, and new signs to improve safety in tunnels.
Both agreements, the Vienna Convention and the Geneva Protocol, reflected a common consensus on road traffic that evolved primarily in mid-century Europe. Most jurisdictions outside Europe have not adopted any treaties, and maintain their own road traffic signal systems. For example, the US Manual on Uniform Traffic Control Devices (MUTCD) does not follow the symbol policy set forth by the Vienna Convention; For example, signs for speed limits and prohibited parking are among the most visible differences. In order for the agreement to be accepted in as many countries as possible, the convention allows for some variations, for example the danger warning signs can be triangular or diamond-shaped and the road markings can be yellow or white.
Rules
traffic signs
In article 2 the convention divides all traffic signs into the following categories (A-H):
The convention then establishes precise colors, sizes, and shapes for each of these classes of signs:.
It also specifies the symbols and pictograms that can be used, as well as their orientation. When more than one is valid, only one should be used throughout the country. All signs, except those not used at night, must be sufficiently reflective to be seen in the dark at a distance with headlights on.
