Signal 20 indicates that an officer should:

Signal 20, indicating that an officer should contact a given place in person, is used for situations requiring direct interaction or follow-up at a specific location. This might occur during a situation where an officer needs to gather more information, assess a scene, or engage with individuals at a designated site. Officers rely on this signal to ensure that they are physically present to manage circumstances that cannot be adequately addressed through communication alone.

While other options suggest important actions officers might take in various scenarios, they do not encompass the necessity of physical presence that signal 20 commands. For instance, requesting additional units or updating dispatch focuses on the coordination of resources rather than direct engagement at a location. Observing traffic patterns, while vital for traffic enforcement, does not relate to the direct contact aspect inherent in signal 20. Thus, the context of needing personal interaction at a specified location makes the understanding of this signal crucial for effective and responsive law enforcement operations.
