All vehicle insurance policies will now include personal accident cover worth Rs 15 lakh in case of the death of the owner while driving or riding. This new rule will help the families of accident victims especially two-wheeler riders who are most of the time under-insured. The Insurance Regulatory and Development Authority (IRDAI) in a circular has directed all third-party insurance companies to include this cover to vehicle owners-drivers of all vehicles (two-wheelers, three-wheelers, passenger vehicles and commercial vehicles) for an additional premium of Rs 750 per year (annual insurance policy). This will now be part of the mandatory insurance cover that is a must for all vehicle owners.
