If I buy my commercial vehicle in a particular city and then I move to another city, which premium rate will be applied?

The place where the commercial vehicle is registered is the place that will be considered for applying the premium rate. Even if you shift to another city or town, the same rate will be applied to your vehicle. If a vehicle is registered in a town viz- a -viz a city, the Zone B premium rate will be applied. For vehicles registered in cities, Zone A premium rate is applied to them.
