Road Sign Design: Why Do Signs Have Eight Corners?

Road sign design is not intended for drivers to read the text. Visual elements and shapes play a key role in instant recognition.

Why do signs have eight corners? The answer lies in the history of road traffic.

The decision to use an octagonal shape has been around for over a century. This design has gained popularity worldwide due to its effectiveness.

Eight corners allow drivers to identify the sign even in poor visibility or from a long distance. This improves road safety.
