Our national highways started getting a direction with the quadrilateral connectivity initiated by AB Vajpayee during his prime ministership. While some of them are yet to be completed, we today have in many locations these roads being upgraded to 6 lanes. Great news for the road user.
For those who regularly use the highways danger is always a micro second away. Many lives are lost due to bad maintenance inspite of the steep toll that is collected, recklessness of the driver, people driving the wrong way to save a round about U - turn.Most threatening and unsuspected danger is from the Green dividers.
We have cattle grazing happily on the grass and plants that are grown on the divider. It could be a heavy track that might rattle it or a playful run you might suddenly find a Cow/Buffalo on your face and next thing you know either it has toppled you or you have toppled it.

By the time our car got to a stop and we recover and see around us, we see small glass pieces all over the car in our hair and everywhere possible. We look back only to see the buffalo on the road bleeding, later we got to know poor fellow died on the spot.
While we escaped with minor bruises (probably thanks to the vehicle in which we were traveling) the suddenness of the whole event got us dazed. As we later analised, we realised my cousin just escaped a major lung puncture, if only the horn got to enter the window glass instead of the front windshield.

As Highway users we are paying the toll for using the road and also constantly face teh threat of something happening to us. It may be worthwhile reading this article too, about road safety on our national highways.(http://www.team-bhp.com/forum/street-experiences/144117-cattle-real-menace-indian-highways.html)
Why our highways are not fenced as per the rules.
Cant NHAI at least get the dividers fenced, to prevent cattle coming in to the middle of a highway to graze.
What action do they take against the cattle owners who allow their cattle to graze on the highways.
Is it a PD or the security patrol who is responsible for these accidents on the highways.
In a normal way these questions will go un-answered, but as road users it is better we keep a watch for these cattle running across our roads and keep ourselves safe from a collision.
