The year 1920 marks a significant period in road sign history, as standardization efforts began to take shape across the United States. This era brought about not only visual updates but also introduced the concept of symbols and universal icons we're familiar with today.

Delving into the 1920s illustrates a fascinating transition phase in road signs, where tradition met innovation. Let's explore this decade's impact on road safety by discussing the main aspects of 1920 road signs and their advancements.

Evolution of 1920 Road Signs: Shapes and Colors
Up until the 1920s, road signs were mostly rectangular, making them somewhat indistinguishable from one another. The 1920s introduced new shapes, such as octagons, for stop signs and diamonds for warning signs, enhancing their distinctiveness and legibility.

Colors also played a more prominent role in sign design. Stop signs, for instance, adopted the immediate and attention-grabbing red, whereas warning signs started incorporating orange hues. This evolution helped drivers scan and respond to signs more efficiently.
Introduction of Symbols

Before 1920, most road signs were text-heavy, causing comprehension issues among illiterate drivers or those challenged by language barriers. The 1920s witnessed the introduction of visual symbols, dramatically improving sign universality. An excellent example is the iconic horseshoe curve sign, which visually communicated the upcoming sharp bend to drivers.
Other symbols that emerged during this period included the dotting dial sign for telephone booths and the post office sign, featuring a /\slash with a star-like shape at the intersection. These symbols, though simple, conveyed vital information effectively.
