Is NCB applicable for comprehensive commercial vehicle insurance?

Yes, just like any other comprehensive vehicle insurance policy, the NCB is also applicable to your comprehensive commercial vehicle insurance policy. The first year of your insurance policy that passes without you having to make a claim gives you a discount of 20% on the premium you pay for your renewal. This discount increases to a massive 50% on the completion of the fifth year of your insurance policy that passes without making a claim, after which the NCB stays constant.
