Road signs in Argentina
In Argentina, road signs are similar to those of other South American countries. They are something of a compromise between the Vienna Convention signs used in Europe and the U.S. system. Argentina is right-hand traffic.
While warning signs are mostly based on the US's MUTCD (yellow diamond shape), information, mandatory and prohibitory signs were taken from the Vienna Convention diagrams.
In 1994, the Congress of Argentina promulgated Law n° 24.449 with the purpose of establishing a single rules system within the whole country. The diagrams of those road signs were published in the "Anex L" of Decree 779 (promulgated in 1995), which ruled Law 24.449 and added visual information to its article 22.
Starting in 2013, the National Directorate of Roads of Argentina (DNV) published a series of visual identity guides that detailed specific norms for the installation and use of road signs along the country, including fonts, colors, materials, and measures, among other items. Those manuals also included an update (released in 2017) to some road signs.
