Car and two-wheeler insurance in India, explained
Third-party versus comprehensive cover, what IDV really means, whether zero-depreciation is worth it, and what to do if your policy has already expired.

In short
Every vehicle on an Indian road must carry third-party liability cover under Section 146 of the Motor Vehicles Act 1988. That covers damage you cause to others, not to your own vehicle. A comprehensive policy adds own-damage cover — accidents, fire, theft and natural events — and is what most owners hold while a vehicle still has meaningful value.
Third-party versus comprehensive
| Third-party only | Comprehensive | |
|---|---|---|
| Legally required | Yes | Covers the requirement and more |
| Damage to others | Covered | Covered |
| Damage to your vehicle | Not covered | Covered |
| Theft | Not covered | Covered |
| Fire and natural events | Not covered | Covered |
| Premium | Set by IRDAI | Priced by the insurer |
The decision is mostly about the vehicle's remaining value. On a new car, comprehensive is not really optional. On a fifteen-year-old vehicle where the IDV has fallen to a small figure, the own-damage portion is buying less than it used to, and some owners reasonably drop back to third-party.
IDV: the number that caps your claim
Insured Declared Value is what your insurer agrees the vehicle is worth today. It is calculated by applying a depreciation schedule to the manufacturer's listed price, and it sets the ceiling on a theft or total-loss payout.
- Lower IDV
- Lower premium, but a smaller cheque if the vehicle is written off or stolen.
- Higher IDV
- Higher premium, closer to what replacing the vehicle would actually cost you.
- Where it comes from
- A depreciation schedule applied to the listed price, adjusted for the vehicle’s age.
Depreciation, and zero-dep cover
In an ordinary own-damage claim, the insurer does not pay the full cost of replacement parts. It deducts depreciation, and the deduction is steepest on plastic, rubber and fibre components — which is most of a modern bumper and most of a modern interior.
A zero-depreciation add-on removes that deduction, so more of the repair is covered. It costs more, is generally available only on vehicles below a certain age, and most policies cap how many such claims you can make in a year. On a newer vehicle it typically justifies itself in one significant repair.
No Claim Bonus
NCB is a discount on the own-damage portion of your premium, earned for each claim-free year and stepping up to a substantial reduction after several. Three things about it are worth knowing:
- It is yours, not the insurer's. It transfers when you switch insurer and when you replace the vehicle. You may need an NCB certificate as proof.
- One claim resets it. Which is why a minor repair costing less than the bonus you would forfeit is often better paid out of pocket.
- A long gap after expiry kills it. Let the policy lapse for more than 90 days and the accumulated bonus is generally lost.
Add-ons worth paying for
| Add-on | What it does | Worth it if |
|---|---|---|
| Zero depreciation | Removes depreciation on replaced parts | The vehicle is newer and eligible |
| Engine protect | Covers engine damage including water ingress | You park or drive where flooding happens |
| Return to invoice | Pays the original invoice value on total loss, not the depreciated IDV | The vehicle is nearly new |
| Consumables | Covers oils, coolants and other items normally excluded | You want a repair bill with no surprises |
| Roadside assistance | Towing and on-road help | You drive long distances or at odd hours |
If your policy has already expired
This is the situation people search for most often, and it is worth being direct about it: driving an uninsured vehicle is an offence, and the longer the gap runs, the more it costs you.
- 1Stop driving the vehicle until cover is in force.
- 2Start the renewal straight away — every day of delay is a day of exposure.
- 3Expect a break-in inspection: the insurer will want to see the vehicle’s current condition, usually via an app or a surveyor visit.
- 4Renew within 90 days of expiry to keep your No Claim Bonus.
- 5Have the previous policy or NCB certificate ready as proof of your bonus.
Making a claim
- 1Make sure everyone is safe, and photograph the scene and the damage before anything is moved.
- 2Inform the insurer as soon as you reasonably can — most policies specify a window.
- 3File a police report where there is injury, theft, or damage to a third party.
- 4Use a network garage if you want the claim settled cashless.
- 5Expect to bear the compulsory deductible, plus depreciation unless you hold zero-dep cover.

Frequently Asked Questions
Is third-party motor insurance mandatory in India?
Yes. Section 146 of the Motor Vehicles Act 1988 requires every vehicle used in a public place to carry at least third-party liability insurance, and driving without it is a punishable offence. Third-party cover pays for injury, death or property damage you cause to someone else — it does not pay to repair your own vehicle.
What is IDV in car insurance?
IDV, or Insured Declared Value, is the current value of your vehicle as agreed with the insurer, arrived at by applying a depreciation schedule to the manufacturer’s listed price. It is the maximum the insurer will pay if the vehicle is stolen or written off. A lower IDV reduces your premium but also reduces a total-loss payout, so it is worth setting deliberately rather than accepting a default.
What is zero depreciation cover and is it worth it?
In a normal own-damage claim the insurer deducts depreciation on replaced parts — particularly plastic, rubber and fibre — so you pay part of the repair. A zero-depreciation add-on removes that deduction. It costs more, is usually available only for newer vehicles, and policies commonly limit how many such claims you can make in a year. On a newer car it generally pays for itself in a single significant repair.
Can I renew my car insurance after it has expired?
Yes, but with consequences. Driving in the meantime is an offence, and the insurer will usually require a physical break-in inspection before issuing a new policy. You also risk losing accumulated No Claim Bonus if the gap runs beyond 90 days from expiry. Renewing before the expiry date avoids both the inspection and the loss.
What happens to my No Claim Bonus if I switch insurers?
The No Claim Bonus belongs to you, not to the insurer, so it transfers when you move. You will normally need an NCB certificate or the previous policy document as proof. It also transfers to a new vehicle when you sell and replace your car. Making a claim resets the bonus at the next renewal, which is why small repairs are sometimes better paid out of pocket.
Does motor insurance cover flood damage?
Own-damage cover under a comprehensive policy generally covers damage from natural events including flooding. The significant exclusion to know about is consequential damage — notably attempting to start a car whose engine has taken in water, which is typically not covered unless you hold an engine-protect add-on. If a vehicle is flooded, the safest step is not to start it.
Is a personal car policy valid if I use the car for business?
Not necessarily. Vehicles used to carry goods or passengers commercially need a commercial vehicle policy, and a private-car policy can be contested if the vehicle was being used commercially at the time of an incident. Ordinary commuting to your own workplace is not commercial use, but carrying paying passengers or goods for hire is.
Does Finzip charge me a fee for motor insurance?
No. Finzip Private Limited is an IRDAI-registered Corporate Agent (Composite), registration number CA0985. The policy is issued by the insurer, and Finzip is remunerated by that insurer in accordance with IRDAI regulations. You pay only the premium set by the insurer.
