Dallas Police Radio Codes and Signals Practice Test 2026 – Complete Study Resource

In this code system, the two-part numbers combine a general category with a specific subcode. The pairing 41-40 is the designated signal for “Other in Progress”—a catch-all used when an ongoing task doesn’t fit any of the more defined categories. It tells dispatchers and officers that something still needs attention and is actively being handled, but it isn’t one of the standard listed types.

That’s why this is the best answer: it directly matches the meaning assigned to this code in the DPD code set. The other options correspond to different, predefined statuses and do not convey the “Other in Progress” designation.
