Key takeaways
- Third-party cover is legally compulsory; comprehensive cover adds protection for your own vehicle and is usually worth the extra premium.
- Insured Declared Value (IDV) should reflect your car’s realistic current market value — too low under-insures you, too high raises premium unnecessarily.
- No-Claim Bonus (NCB) is attached to you, not the vehicle, and can be transferred — never let it lapse over a small claim.
- Zero-depreciation and engine-protection add-ons matter more for newer cars and those in flood-prone or high-traffic areas.
Third-party vs comprehensive cover
| Cover type | What it pays for | Who it suits |
|---|---|---|
| Third-party (liability only) | Injury, death or property damage you cause to others | Legally the minimum; rarely enough on its own |
| Comprehensive (own-damage + third-party) | The above, plus damage to your own car from accident, fire, theft and natural calamities | Most car owners, especially for newer or financed vehicles |
| Comprehensive + add-ons | Comprehensive cover plus optional riders like zero-depreciation, engine protection, roadside assistance | Newer cars, high-value cars, or owners who want fewer out-of-pocket surprises at claim time |
Getting the Insured Declared Value (IDV) right
IDV is the maximum amount the insurer will pay if your car is stolen or damaged beyond repair — effectively its current market value after depreciation. A lower IDV reduces your premium but also caps your payout; an inflated IDV raises premium without a matching benefit, since the insurer will still only pay the assessed value at claim time. Most insurers calculate IDV using a standard depreciation schedule — check it rather than accepting a default figure.
Add-ons worth understanding
- Zero-depreciation cover: claims are settled without deducting depreciation on replaced parts — valuable for cars under 3–5 years old.
- Engine and gearbox protection: covers damage from water ingress or oil leakage, often excluded under standard comprehensive cover.
- Roadside assistance: towing, minor repairs and fuel delivery in case of a breakdown.
- Return-to-invoice cover: pays the original invoice value rather than the depreciated IDV in case of total loss or theft.
- No-Claim Bonus (NCB) protection: lets you make a limited number of claims without losing your accumulated NCB discount.
How to compare car insurance plans
- Set a realistic IDV rather than accepting the lowest or highest option offered.
- Compare the cashless garage network near where you live and drive.
- Check what add-ons are included versus charged separately, and whether they matter for your car’s age and use.
- Look at the insurer’s claim settlement ratio and reported turnaround time for motor claims.
- Protect your No-Claim Bonus — for small repair costs, paying out of pocket can be cheaper over time than losing NCB.
Rules that protect you
Third-party motor insurance is mandatory under the Motor Vehicles Act for any vehicle used on Indian roads; own-damage cover is optional but strongly advisable. IRDAI requires general insurers to issue a Customer Information Sheet, offer a No-Claim Bonus for claim-free years (which is tied to the policyholder, not the vehicle, and is transferable), and follow standard grievance-redressal timelines. Home, travel and personal accident products vary more by insurer, so the policy wording and Customer Information Sheet are what actually govern a claim. Rules can change — confirm current terms with your insurer or IRDAI.
Frequently asked questions
Which car insurance plan is best?
For most owners, comprehensive cover with an accurate Insured Declared Value, from an insurer with a strong claim-settlement record and a good cashless garage network near you, is the best starting point. Add zero-depreciation or engine protection for newer or higher-value cars.
Is third-party car insurance enough?
It meets the legal minimum and covers damage you cause to others, but it does not pay for damage to your own car from an accident, fire or theft. Most owners find comprehensive cover worthwhile once the vehicle has meaningful value.
What is IDV in car insurance?
Insured Declared Value is the maximum amount your insurer will pay if the car is stolen or damaged beyond economical repair — broadly its current market value after standard depreciation. Set it accurately rather than too low or too high.
Does No-Claim Bonus transfer if I change insurers or buy a new car?
Yes, generally. No-Claim Bonus is linked to you as the policyholder rather than the vehicle or insurer, and can typically be carried over subject to the process and timelines your insurer specifies.
Is zero-depreciation cover worth it?
Often yes for cars under about 3 to 5 years old, since it removes the depreciation deduction on replaced parts at claim time. For older cars, the extra premium may outweigh the benefit — compare the cost against your car’s age and typical repair costs.
