Which signal corresponds to Safety Checkpoint?

• A. Air Rifle
• B. Hazardous Material - Chemical or Biological
• C. Traffic Detail
• D. Safety Checkpoint

Answer: (D)

In APD Signals, each label is a fixed designation for a specific assignment or scene. When you need a Safety Checkpoint, the signal used is the one named Safety Checkpoint. That label directly communicates that a security or screening point is in operation, guiding responders to establish and manage access, safety checks, and orderly flow at the location.

The other signals point to different tasks: one relates to an air rifle situation, another to hazardous materials, and another to directing traffic. None of those indicate a checkpoint, so they’re not appropriate for conveying the Safety Checkpoint request.
