Can't Zhongshan ambulance leave Dongguan?

Yes, it belongs to a long-distance ambulance.

An ambulance refers to a vehicle that rescues patients. The word "ambulance" on the car body is written backwards, so that the driver in front can directly see the word "ambulance" in the positive direction through the rearview mirror, thus quickly giving way.

With the flashing of warning lights and sirens, there is no doubt that the ambulance is on its way to the emergency call site. All traffic arteries will be magically released for it, and drivers can drive on the edge of the roadway, sidewalks or even in the opposite direction-anywhere, as long as ambulances can pass, just like firefighters who go to the fire site, ambulance workers also need to race against time, because this may mean the difference between life and death.
