Oakland Police 900 Radio Codes Test 2026 – Complete Practice Resource

The essential idea is how the 900 radio codes convey the nature of the incident. In this system, 415 is used for Disturbing the Peace, and the suffix A designates a specific subtype—Auto—indicating a disturbance involving a vehicle or occurring in a vehicle context. So the code 415A maps to Disturbing the Peace - Auto, making it the correct match. The other offenses—Murder, Rape, and Indecent Exposure—have different codes that pertain to those crimes, so they don’t correspond to 415A.
