It is a myth that carriers are specially allowed for commercial cars in India. The truth is that even private cars can install luggage carriers whenever they want to, without any legal consequences.
How often do we feel the need for extra spaces to accommodate our luggage bags while travelling? Most of the time, whether we are out for camping or a road trip, or travelling to a different city, we end up stuffing the extra baggage inside the car, leaving little or no space for the co-passengers.
