While give way and yield essentially have the same meaning in this context, many countries have a clear preference of one term over the other.The triangular yield sign was used as early as 1937, when it was introduced in Denmark in red and white (matching the Danish flag),[1] in 1938 when it was codified in Czechoslovakia in a blue-white variant without words,[2] and in 1939 in the Protectorate of Bohemia and Moravia which adopted the current red-white variant.The inverted equilateral triangle was then adopted by the Vienna Convention on Road Signs and Signals as the international standard.[11] In New Zealand, the original design also used the keystone shape as in the United States but used a black background with a red border.[13] In Wales, some signs bear a bilingual legend: the Welsh ildiwch appears above give way.
