Upon receipt of a 997, 998 or 999 broadcast, Deputies are authorized to respond Code 3, governed by the limitations outlined in the previous subsections.
Responding field units shall identify themselves and give the SCC a conservative estimated time of arrival based on distance, traffic and weather conditions.
The first field units arriving should evaluate the need for additional assistance. If it is deemed that additional emergency help is no longer necessary, a Code 4 shall be broadcast through the SCC.
Upon receipt of a Code 4, responding field units shall discontinue the Code 3 operation and return to their districts unless requested to continue to the location under normal driving conditions.
