What is the period of a commercial auto insurance policy?

In India, a commercial vehicle insurance policy is valid for one year and it has to be renewed before the due date.  The policyholder should make the payments on time and not let the policy lapse. Insurance companies carry out complete vehicle inspection, in case the insurance policy lapses even for a day. You can also lose your no-claim bonus if you allow your comprehensive insurance policy to lapse for more than 90 days.
