Thanks for the very essential information.
If I would have read this before 5 years, I could be saved of many bucks. Once on way to Shimla from Delhi, at Himachal Pradesh border, Police demanded from us the hill driving license, said it is a must to drive in hilly areas. Naturally we didn't have that, so he asked Rs. 2000 as fine. We settled the case in Rs. 500 & entourage nowhere this license was demanded. How stupid of us.
