Type if motor license required

RTO Rules change State wise. However, in most of the State for all type of heavy vehicles license has been categorised. You should asked such query in RTO. This is not proper forum to ask this question. 

Hi Amar, 

I do not think that you have to apply for new license, it will be included in your industrial vehicle license. 

I have got this info from random google search, so please verify this with government officials. I have listed down some of the resources which can be useful for you.
