A yield sign is a traffic control device that indicates to drivers that they must slow down and prepare to stop if necessary. It is typically shaped like an inverted triangle and is colored red and white. The purpose of a yield sign is to give the right of way to other vehicles or pedestrians, ensuring safe merging and crossing at intersections.
When approaching a yield sign, drivers should look for oncoming traffic and determine if it is safe to proceed. If there are no vehicles or pedestrians, they may continue without stopping. However, if there is traffic, they must yield, allowing others to pass first.
