The road marking accompanying the sign consists of a large inverted triangle painted just before the place to give way, which is marked by broken white lines across the road. The United Kingdom's Road Traffic Act calls for give way signs and road markings at junctions ( crossroads) where the give-way rule is to apply.

The triangular yield sign was used as early as 1937, when it was introduced in Denmark in red and white (matching the Danish flag), in 1938 when it was codified in Czechoslovakia in a blue-white variant without words, and in 1939 in the Protectorate of Bohemia and Moravia which adopted the current red-white variant. ![]() This chart is based on official government usage in the English language and excludes indirect translations from other languages.īlue give-way sign as used in Czechoslovakia, 1938Ī black triangle (within the standard down-arrow-shape of stop signs) was a symbol of "stop for all vehicles" from about 1925 in Germany.

Under the Vienna Convention on Road Signs and Signals, the international standard for the modern sign is an inverted equilateral triangle with a red border and either a white or yellow background. In contrast, a stop sign requires each driver to stop completely before proceeding, whether or not other traffic is present. A driver who stops or slows down to let another vehicle through has yielded the right of way to that vehicle. In road transport, a yield or give way sign indicates that merging drivers must prepare to stop if necessary to let a driver on another approach proceed. ![]()
