NHAI — About animals on road

Address:

Kota, Rajasthan

On 30th december 2013, iam returning from jaipur to kota along my family on my wagon r car rj20 cc 0862, it is rainy day.
At 1:50 pm, when i pass second toll tax from jaipur side after mahendwass, suddenly a cow was came in front of car, now a days the condition of road is very good i was on about 90 kms/hr speed, u think whats happend, thanks god no one was injured.
My point is that when we pay toll tax, is it only to maintain road condition or all others problem solved by them.
I want along with road condition, animals should also restrict on the nhai by providing barricades.
On this day only my car was damaged .But many o[censored]s lost their life .
Who is responsible?
