This site has lots of information about ambulances, including a video tour of the interior: http://video.about.com/firstaid/Tour-of-an-Ambulance.htm
This is because the word AMBULANCE can be read through a rearview mirror of the vehicle in front of it.
The word "Ambulance" is printed backwards on the front of the ambulance so you can read it in the mirror the right way around
So a driver in front of an ambulance can read the word when they look in the rear view mirror
It is in reverse so that passengers in vehicles in front of the ambulance can read the word in their car's mirrors.
So that if you see it in your rear-view mirror, you can read it instantly, and pull over to let the ambulance go by (which is the law in most if not all states).
So that it can be read by drivers on the road who are looking in their mirrors.
So you will use common sense prior to posting such a question. It's backwards so that a driver in front of the ambulance will be able to read "Ambulance" in his rear-view mirror.
So you can read it in a cars rear view mirror.
Bcoz the name written in opposite direction looks on the correct direction when viewed through the mirror so that is the reason…..if a vehicle going in front of the ambulance can read it correctly and give a way to go a head
The aim of this is to allow people driving in front of the vehicle (ambulance) to see the word "AMBULANCE" when he/she looks in the rear view mirror. If the word was not reversed, the driver of the car ahead of the vehicle would see: "ECNALUBMA"

The word ambulance on an ambulance is backwards because when you're in front of an ambulance and there's an emergency you would usually see from your rear view mirror. When you see something in a mirror it is always backwards. so when you see the word ambulance on an ambulance, you would see it normally.
