ELI5: Explain Like I'm 5

Traffic sign design

Okay kiddo, you know how when we are driving or walking, we sometimes see pictures or words on a sign that tell us to do something, like stop or slow down? That's a traffic sign!

The people who make these signs have to make sure they are easy to understand for everyone, even young kids like you. They use different colors, shapes and symbols to give us information about the road ahead.

For example, a red octagon sign means STOP, and a yellow diamond sign means CAUTION. The colors help our brains understand quickly what we need to do.

The size of the sign is also important. Signs that need to be seen from far away, like on a highway, are usually bigger and have bigger letters.

And lastly, the words and pictures on the sign need to be simple and clear. They use pictures, arrows, and sometimes even emojis to help us understand what the sign means.

So that's how traffic signs are made and designed! They are like little helpers for us to be safe while driving or walking on the road.
