What traffic control device is present for vehicle 2?

The yield sign is designed to indicate that a vehicle must yield the right of way to other traffic. It is a critical traffic control device that helps ensure safety at intersections and merges by alerting drivers to potential conflicts with other vehicles or pedestrians. When present, it requires drivers to slow down and prepare to stop if necessary, allowing them to assess the traffic conditions before proceeding. This enhances traffic flow and reduces the likelihood of accidents.

In contrast, a stop sign requires vehicles to come to a complete stop, allowing for more definitive control at intersections, while a speed limit sign provides guidance on the maximum speed allowed in a particular area. A traffic light regulates vehicle and pedestrian movement with clear and distinct phases (red, yellow, green) but is not always present in every traffic scenario, particularly in less complex environments. Each of these devices plays a unique role in traffic management, but the yield sign specifically emphasizes giving way to other road users, making it the appropriate answer in this context.
