Often heard, as: "255 In Service." A variable number, typically
in the 200 range. This is a deputy's car number. In this document, 255
and 222 are used as car numbers. Sometimes you will hear numbers outside
the 200 range used as call numbers; these typically indicate specialty
employees of SCSD who are driving vehicles other than SCSD cruisers.
For example, 6630 is a transport vehicle for inmates.
Often heard, as: "Can I get an RQ on ..." Means: Registration
Query. The deputy is asking the dispatcher to look up information
about a car with Tennessee tags, or with nearby-state (MS,
AR) tags as specified by the deputy. An RQ request is followed by the
car's license plate.
Often heard, as: "Can I get a DQ on ..." Means: Driver
Query. The deputy is asking the dispatcher to look up information
about an individual. Normally, the DQ request is followed by a driver's
license number. If the subject does not have a driver's license, the
deputy will use SSN as a second choice. Occasionally, if the subject
has no ID at all, a deputy will request a DQ by the person's name.
Often heard as: "Can I get a QV on ..." Means: Query
Vehicle. The deputy is asking the dispatcher to look up information
about a car with out of state tags. A QV request is followed
by the car's license plate.
Rarely heard, as: "Can I get a GQ on ..." Means: Gun
Query. The deputy is asking the dispatcher for information
on a gun registration. This will usually be followed by the serial number
of the firearm or permit.
Rarely heard, as: "Can I get a BQ on ..." I believe this is
a Boat Query where the deputy is asking the dispatcher
for registration information about a boat being towed behind a vehicle.
May not exist - may have misinterpreted some DQs.
Rarely heard, as: "Negative NCIC ..." Means: National
Crime Information Center. Normally heard from dispatch in response
to a DQ, this indicates whether or not a subject has any outstanding
warrants nationwide. From my scanning experience, NCIC is frequently
down or unable to be queried (your tax dollars at work).
Often heard, as: "Check 255." Means: Received OK.
Deputies and dispatchers will use "check" to indicate that
they received and understood the message. The syntax order generally
determines which end of the conversation is speaking; i.e. "255
Check" is car #255 acknowledging the dispatcher, and "Check
255" is the dispatcher acknowledging car #255's last transmission.
Often, when dispatch checks, they will issue a timestamp as well, such
as "check 255 fourteen fifty-three" to indicate 2:53 PM. Deputies
do not issue timestamps.
1: Often heard, as: "Respond code 1."
Means: Silent Alarm. The dispatcher is directing the
deputy to respond to the call with no lights or sirens. Typically used
for low-priority calls or when there is e.g. a prowler who would flee
if he saw/heard the cops coming.
2: Often heard, as: "Respond code 2."
Means: Lights. The dispatcher is directing the deputy
to respond to the call with his lightbar on, but no siren. Used on most
calls, this allows the deputy to proceed with speed but without causing
3: Often heard, as: "Respond code 3."
Means: Lights and Siren. The dispatcher is directing
the deputy to respond to the call with lights and siren turned on. Typically
used in emergency situations.
Often heard, as: "255 are you direct?" Means: Heard
Prior Transmission About Me. For example, if car #222 calls
dispatch and asks for car #255 to meet him at a location, the dispatcher
may ask, "255 are you direct?" Meaning, "Car #255, did
you just hear the message that car #222 sent to me about you?"
If yes, car #255 would respond "255 direct," indicating he
had heard car #222's request. This saves the dispatcher from having
to waste time repeating the entire request.
Routine Traffic: Rarely heard, as "All units hold routine
traffic ..." Means: Listen, Don't Talk. Just what
it says, this order comes from the dispatcher if there is a serious
(e.g. gunshot) situation going on, or if there is a lengthy broadcast
coming from either a dispatcher or another agency. For example, in the
case of a missing person or an AMBER Alert, dispatch may call Hold Routine
Traffic while a one-minute-plus broadcast regarding the missing person
is sent out to all cars. During an HRT, deputies are not supposed to
call in unless they're involved in the situation.
Service: Often heard, as: "255 In Service." Means:
Available for Calls. Occasionally shortened, as "255
In." After a deputy is either dispatched to a call, or goes Special,
the dispatcher marks them unavailable to respond to calls. Once they
finish the task, they will radio In Service. This means they're ready
to be dispatched elsewhere.
Often heard, as: "Occupied one female white." Means: Who's
In the Car. When calling in an RQ or QV, a deputy will often
indicate who is inside the car. The driver is listed first. For example,
if a deputy pulls over a car with tag JUV-123, driven by a white female
with two black male passengers, the call would likely be "255 show
me special at [location] with Tennessee Juliet Uniform Victor 1 2 3,
occupied one female white two male black."
Often heard, as: "255 Respond ..." Means: Go to Call.
The dispatcher is sending a deputy to respond to a call. Details regarding
the nature of the call either precede or follow the Respond order. Normally
given in conjunction with a Code 1, Code 2, or Code 3 designation. Frequently
in the form, "255 Residential alarm, covers front and rear entry,
8850 Foo Cove, eight eight five oh Foo cove, respond code 1."
Sometimes heard, as: "Can I get a rolling RQ on ..." Means:
Driving / Not Stopped. The deputy suspects that the
car he's following is up to something, but does not yet have reason
to pull it over. He calls dispatch to see if there is anything wrong.
Frequently used in cases of suspected expired tags. For example, a call
for a rolling QV would mean that the deputy is tailing a vehicle from
out of state and wants information about the car. If dispatch indicated
that the car was stolen, or that the tags were expired, the deputy would
go "special" with this subject. Most rolling RQs/QVs wind
13: Occasionally heard, from dispatcher only. Means: Unknown
- I don't hear this very often. Web research shows that in
other areas, it tends to indicate an emergency situation, i.e. an "officer
panic" type of call. However, I have not gotten that impression
from my experience scanning SCSD, it seems to be used casually. (Perhaps
it's the 10-23, bathroom break?) Please email with further info.
Often heard, as: "255, show me special at [location] ..."
Means: Non-dispatched Call. The most common use of
the "special" status is when a deputy pulls a car over for
a traffic violation. A special call will usually involve an implied
RQ. For example, it is common to hear something like "255 show
me special, 40 and 64, Tennessee Quebec Quebec Uniform 5 1 8, green
Chevy Cavalier occupied one male black, one female white." The
dispatcher will automatically reply with the RQ information for TN QQU-518.
When a deputy is "special," he or she will generally not be
dispatched to a call.
