Stop Sign
The red octagonal sign recognized worldwide/Everyday Objects
The standard stop sign is an octagon with white text on a red background, a design adopted internationally under the Vienna Convention on Road Signs and Signals. In the United States, its dimensions are specified by the Manual on Uniform Traffic Control Devices. The octagonal shape was chosen so drivers can recognize it from the back.
