3.2
Fire engines
Special vehicles and scene-commanding vehicles used for fire extinguishment by public security fire brigades and other fire departments.
3.3
Ambulances
Special vehicles used for site medical rescue and auxiliary site medical rescue by emergency rescue and medical institutions as well as disease prevention and control institutions to transfer and rescue patients, or treat emergency epidemic and unexpected public health incidents.
3.4
Engineering rescue vehicles

3.5
Warning lamps
Lamps installed on police cars, fire engines, ambulances and engineering rescue vehicles to send out warning, alerting, danger or emergency signals.
3.6
Reference axis
A line which passes through the geometrical center of primary optical warning device and is parallel to the horizontal plane and vertical to the normal section of warning lamps.
3.7
Symmetry axis
A line which passes the central symmetry point of optical warning device and is parallel to the reference axis.
3.8
Primary optical warning device
Optical warning devices installed on the warning lamps to send out warning, alerting, danger or emergency signals.
Note: The adjacent independent primary optical warning devices which flicker synchronously may be used as a single primary optical warning device.
3.9
