Ambulances have the right of the way, they should be allowed to break any traffic law (except for running over other poeple) because what they are trying to do is save a life. Infact, its a pity to see some morons blocking an ambulance not giving it way .
Tailgating an ambulance is something one must not do. It could lead to detrimental circumstances.
Talking about ambulances, in my recent trip to Chennai I was shocked to see an ambulance with a patient not being allowed to cross a signal on airport road thanks to a motorcade of some politician going along that way. It was downright disgusting to see the ambulance driver, assistant and the family members pleading the cop to let them go.
When I mentioned this to a few friends, they said about a week back, 3 kids hired an ambulance and were smoking drugs and drinking alcohol inside an ambulance. The only instructions the driver got was, stop nowhere. I don't know what kicks those 3 morons got out of it, eventually it landed them all in jail. And now all the ambulances are having to face this treatment since then I am told. Seriously sad state of affairs.
