Dallas Police Department (DPD) Radio Codes and Signals Practice Exam 2026 - Free Radio Codes Practice Questions and Study Guide

The main idea here is using standardized radio codes to convey key information about a subject quickly. The code for someone who is already in the system as an offender is Known Offender. This label tells officers that the individual is in the offender database and may require heightened caution, check of prior records, or access to additional intel. The other terms describe movement or action (Arrived means you’ve reached the destination; En Route means you’re on the way) or an instruction to ignore a prior signal (Disregard). So the term that directly indicates offender status is Known Offender.
