Code numbers in this radio system map directly to the subject of the call. Code 30 is used to indicate a prisoner—someone in custody, usually in the context of transporting or reporting a detainee. That’s why it’s the correct match for this code. The other subjects listed (sick person, dead person, criminal mischief) are covered by different codes, not Code 30, so they don’t fit this number. Knowing that Code 30 equals a prisoner helps you quickly interpret messages and respond appropriately.
