Why is ambulance is written as ecnalubma?
As we know that a mirror shoes a laterally inverted image.So, if the driver sees the virtual image of an already laterally inverted image, then it will interchange the position of the left and right.
Thus the word Ambulance is written laterally inverted, like ECNALUBMA, so that the traffic ahead would see in the word clearly and would identify the ambulance and give way to the car.
