[Ans] From the late 1920s until the early 1950s, stop signs were not red, but what color?

Step 1 : Introduction to the question "From the late 1920s until the early 1950s, stop signs were not red, but what color?"

Yes, yellow was the standard color for stop signs for nearly 30 years. In fact, the red stop sign has only been the standard for the last 60 years. Before then, the octagonal traffic sign was yellow, with the word STOP in black letters. It wasn’t until 1954 that the stop sign became the bright red color, adorned with white letters that we now know today. This change also served to distinguish the regulatory stop sign from yellow warning signs, and also made the color consistent with that of red traffic signal indications, which for decades had used red to signal "stop".
