316.1 PURPOSE AND SCOPE
This policy provides for the safe and appropriate response to emergency and non-emergency
situations whether dispatched or self-initiated.
316.2 RESPONSE TO CALLS
Officers dispatched "Code-3" shall consider the call an emergency response and proceed
immediately. Officers responding Code-3 shall continuously operate emergency lighting
equipment, including at minimum a steady forward facing red light, and shall sound the siren as
reasonably necessary pursuant to Vehicle Code § 21055.
Responding with emergency light(s) and siren does not relieve the officer of the duty to continue
to drive with due regard for the safety of all persons. The use of any other warning equipment
without a red light and siren does not provide any exemption from the Vehicle Code.
Officers should only respond Code-3 when so dispatched or when circumstances reasonably
indicate an emergency response is required. Officers not authorized to respond Code-3 shall
observe all traffic laws and proceed without the use of emergency lights and siren.
316.3 REQUESTING EMERGENCY ASSISTANCE
Requests for emergency assistance should be limited to those situations where the involved
personnel reasonably believe that there is an immediate threat to the safety of officers, or
assistance is needed to prevent imminent serious harm to a citizen. In any event, where a situation
has stabilized and emergency response is not required, the requesting officer shall immediately
notify Emergency Communications Center as soon as practical.
If circumstances permit, the requesting officer should give the following information:
•The unit number
•The location
•The reason for the request and type of emergency
•The number of units required
316.3.1 NUMBER OF UNITS ASSIGNED
Normally, only two units should respond to an emergency call Code 3, unless the Field Supervisor
or Patrol Lieutenant authorizes an additional unit(s).
316.4 INITIATING CODE 3 RESPONSE
If an officer believes a Code-3 response to any call is appropriate, the officer shall immediately
notify Emergency Communications Center either verbally or via MDC. Generally, only two units
should respond Code-3 to any situation. Should another officer believe a Code-3 response is

Patrol Lieutenant will make a determination as to whether two or more officers driving Code-3 is
appropriate.
316.5 RESPONSIBILITIES OF RESPONDING OFFICERS
Officers shall exercise sound judgment and care with due regard for life and property when
responding to an emergency call. Officers shall reduce speed at all street intersections to such a
degree that they shall have complete control of the vehicle.
The decision to continue a Code-3 response is at the discretion of the officer. If, in the officer's
judgment, the roadway conditions or traffic congestion does not permit such a response without
unreasonable risk, the officer may elect to respond to the call without the use of red lights and
siren at the legal speed limit. In such an event, the officer should immediately notify Emergency
Communications Center. An officer shall also discontinue the Code-3 response when directed by
a supervisor.
Upon receiving authorization or determining a Code-3 response is appropriate, an officer shall
immediately give the location from which he/she is responding when practical and if it does not
interfere with priority communications.
316.6 COMMUNICATIONS RESPONSIBILITIES
A dispatcher shall assign a Code-3 response when an officer requests emergency assistance or
available information reasonably indicates that the public is threatened with serious injury or death
and immediate police response is needed. In all other circumstances, the dispatcher shall obtain
authorization from the Watch Commander or a field supervisor prior to assigning units Code-3 .
The dispatcher shall:
(a)Attempt to assign the closest available unit to the location requiring assistance
(b)Immediately notify the Watch Commander
(c)Confirm the location from which the unit is responding
(d)Notify and coordinate allied emergency services (e.g., fire and ambulance)
(e)Continue to obtain and broadcast information as necessary concerning the response
and monitor the situation until it is stabilized or terminated
(f)Control all radio communications during the emergency and coordinate assistance
under the direction of the Watch Commander or field supervisor
316.7 SUPERVISORY RESPONSIBILITIES
Upon being notified that a Code-3 response has been initiated, the Watch Commander or the field
supervisor shall verify the following:
(a)The proper response has been initiated

(c)Affected outside jurisdictions are being notified as practical
The field supervisor shall monitor the response until it has been stabilized or terminated and assert
control by directing units into or out of the response if necessary. If, in the supervisor's judgment,
the circumstances require additional units to be assigned a Code-3 response, the supervisor may
do so.
It is the supervisor's responsibility to terminate a Code-3 response that, in his/her judgment is
inappropriate due
