Motor insurance cover types and add-ons compared
| Cover or add-on | What it pays | Good for | Watch out for |
|---|---|---|---|
| Third-party (liability-only) | Death, injury and property damage you cause to others; nothing for your own vehicle | Old, low-value vehicles you could afford to replace | No cover for theft, fire, flood or your own repairs |
| Standalone own-damage | Damage to and theft of your own vehicle | Cars and bikes that already have a valid long-term TP policy | Only valid alongside a separate active TP policy |
| Comprehensive (package) | Third-party liability plus own damage in one policy | Most cars and bikes after the new-vehicle TP term | Compare IDV and deductibles, not just premium |
| Zero depreciation | Removes depreciation on replaced parts in OD claims | Newer cars, and owners who would claim for panel and bumper damage | Often limited to a set number of claims a year and a maximum vehicle age |
Frequently asked questions
Is third-party car insurance compulsory in India?
Yes. Section 146 of the Motor Vehicles Act, 1988 makes third-party insurance compulsory for every motor vehicle used in a public place. Driving without it is punishable under section 196 with a fine of ₹2,000 and/or up to three months' imprisonment for a first offence, and ₹4,000 for a repeat offence.
Is there a grace period for renewing motor insurance?
No. Cover ends at the expiry date and time on your schedule, and from that moment the vehicle is uninsured. What is often called a grace period is the 90-day window in which you can still carry forward your No Claim Bonus after expiry; it does not keep you insured.
How much GST is charged on car insurance?
Motor insurance premiums for private cars and two-wheelers attract GST at 18%. The GST rate changes of 22 September 2025 exempted individual life and health insurance but did not exempt motor insurance. Check the premium breakup on your quote.
Why did my renewal premium go up even though I did not claim?
Common reasons are a change in the insurer's own-damage pricing, a higher IDV than you expected, an add-on added to the quote, or the end of a discount. If you moved up an NCB slab, the OD premium should fall, so check the NCB line too. See how the premium is calculated.
Can I switch insurer at renewal and keep my NCB?
Yes. NCB belongs to you, not to the insurer or the car. The new insurer will rely on your previous policy and may ask for a declaration of no claims or the old policy copy. Renewing within 90 days of expiry keeps the NCB.
Is zero depreciation worth it on an older car?
It depends on how likely you are to claim for parts and how much depreciation you would bear. On a three- to five-year-old car, plastic parts are depreciated 50% and metal parts 15–35%, so one bumper and panel claim can cost you more than the add-on. Many insurers stop offering it after a certain age. See the add-ons guide.
Where do I complain if my insurer rejects my claim?
First write to the insurer's grievance redressal officer. If there is no reply within 30 days, or you are not satisfied, you can register on IRDAI's Bima Bharosa portal and approach the Insurance Ombudsman (for claims up to ₹50 lakh) within one year of the insurer's reply, or file a case before the consumer commission. See the complaints guide.
Does a new car need a three-year policy?
A new private car must have third-party cover for three years, and a new two-wheeler for five years, bought at the time of registration. The own-damage part can be annual. That is why many owners renew only the OD part, as a standalone OD policy, in the first years.
