The Rare Norm a few months ago Share Tweet Pin Share yellow yield In the US, Yield signs were standard as yellow from 1954 to 1971. I can’t imagine that any of them are still standing here as they would be too weathered and have been replaced already. In 1971, the official color was changed to red border, white center, as those colors were easier and brighter with reflective paint on them at the time. However, if you ask anyone older that drove at that time, they will often say that current yield signs are yellow. It’s a false memory. In other countries, international standard is red border with white center, although it’s not required. Finland, Greece, Iceland, Kuwait, Poland, Sweden, and Vietnam use red border with yellow center.
