Do this, Don’t do that, Can’t you read the sign!
I’ve always been told that the reason for the big red dot on the “No Turn On Red” sign was for people who can’t read…

But Think of it this way:
What if the sign was in a language you didn’t understand? Would that red dot at the bottom help you figure out what the sign says?

Can you tell what’s straight ahead? or to your right?
