I hope this helps everyone that wants to know.
Code 1 & Code 2 = Lights & Siren authorised, risk of personal injury or damage to property imminent
Code 3 = Routine investigation
VKR = Control Centre / Communications / Despatch.
QV = Query Vehicle check
UIL = Under Influence of Liquor
UID = Under Influence of Drugs
BOLO = Be On the LookOut
EEO = Emergency Examination Order (mental health assessment)
Permanent DNA = DNA of person kept on police file for possible matches with any DNA found at crime scenes
Type 1 = Previous Traffic Offence, speeding or hooning
Type 2A = Previous Traffic Offence, UIL or UID
Type 2B = Previous Traffic Offence, un-licensed or un-insured (un-registered vehicle)
The reason they reveal Permanent DNA information to generals crews is because if they are say for example attending a call out to a disturbance where they believe the person in question (being checked) is involved in an offence which they can not typically prove without scenes of crimes or detectives attending (taking photographs, fingerprints etc) they then know, that no further action is required by them in regards to that matter except to generate possibly a PAC or Job number and refer it to other units. If the person in question had no Permanent DNA they would most likely ask him/her to come back to the Police Station for further questioning, profiling etc
Hope that gives a better understanding of its use. Also VKR, will generally just reveal each and every flag associated to that person, this helps prevent lengthy and unneeded communications (asking for this flag or that flag etc etc etc) between one unit and VKR,
