What shape is a yield sign?

The yield sign is shaped like a triangle, specifically an inverted triangle with a point facing downward. This design is universally recognized as a signal for drivers to reduce speed and yield to any oncoming traffic or pedestrians. The distinctive triangular shape ensures that the sign is easily identifiable, even from a distance, and is consistent with traffic regulations across many jurisdictions, including Illinois. The use of an inverted triangle effectively communicates the importance of yielding without needing additional text, making it an efficient symbol in roadway signage.
