Ambulance Introduction:

Ambulance is a vehicle that rescues patients. The word "AMBULANCE" is written backwards on the body of the vehicle so that the driver of the car in front of him can see the word Ambulance directly in the front direction through the rearview mirror and quickly get out of the way. With warning lights flashing and sirens wailing, there is no doubt that an ambulance is on its way to the scene of an emergency call for an accident.

All major traffic lanes are magically cleared for it, and drivers can drive on the edge of the carriageway, on the sidewalk, even in the opposite direction, anywhere, as long as the ambulance can get through, and like firefighters racing to a fire, paramedics need to make every second count, because it could mean the difference between life and death.
