what is nt and tr in driving licence

In an Indian driving licence, NT stands for Non-Transport and TR stands for Transport, which are subcategories of the Light Motor Vehicle (LMV) class. The LMV-NT licence is for driving vehicles like private cars and jeeps for personal use only. The LMV-TR licence, however, is mandatory for commercial vehicles such as taxis, delivery vans, and light goods carriers, allowing you to operate them for commercial purposes.
