Which code indicates a silent run?

The code that indicates a silent run is associated with the designation for a situation in which an emergency vehicle is responding to a call without using its sirens or lights, thereby minimizing noise and visibility. This is particularly relevant in tactical situations where stealth is necessary.

In the context of ten-codes used in dispatch and law enforcement communications, this specific code represents the concept of proceeding to a location without announcing presence. It underscores the importance of discretion in certain operations. The selected answer reflects an established terminology within the dispatch community, facilitating clear and efficient communication among first responders.

The other codes listed do not pertain to silent runs, as they address different scenarios and instructions pertinent to operations in the field.
