Which sign shape indicates a yield?

A triangular sign shape specifically indicates a yield. This shape is universally recognized as a warning or instruction to drivers that they must slow down and prepare to stop to allow other vehicles or pedestrians to pass before proceeding. The purpose of the yield sign is to facilitate safe merging and the right-of-way in situations where traffic flows intersect, ensuring that drivers are aware they may need to give way to oncoming traffic.

In contrast, an octagonal sign shape is reserved for stop signs, which require drivers to come to a complete stop. Vertical rectangular signs usually convey regulatory information, such as speed limits or prohibitions, while horizontal rectangular signs typically provide guidance or informative details about road conditions or directions. Each of these signs plays a different role in assisting drivers but does not convey the specific instruction to yield like the triangular shape does.
