Third-Party vs Comprehensive Car Insurance in India
Third-party vs comprehensive car insurance: what the Motor Vehicles Act requires, what each pays after an accident, fines, and when third-party is enough.
In this article
Third-party car insurance is the legal minimum and pays only for damage you cause to other people or their property; comprehensive insurance adds own damage cover, which pays for repairs to your own car, theft, fire and natural calamities. As of October 2026, Section 146 of the Motor Vehicles Act, 1988 makes third-party cover compulsory, and driving without it can cost up to ₹2,000 for a first offence. For most cars less than about eight years old, or any car on a loan, comprehensive cover is the sensible choice.
What the law requires
- Section 146, Motor Vehicles Act, 1988: no one may use a motor vehicle in a public place without a policy covering third-party risks.
- Section 196 (as amended in 2019): driving, or allowing someone to drive, an uninsured vehicle is punishable with imprisonment up to three months, or a fine up to ₹2,000, or both, for a first offence; and up to ₹4,000 for a subsequent offence, as of October 2026.
- New cars: since September 2018, a new private car must be sold with 3 years of third-party cover, following a Supreme Court direction. Own damage can be bought for 1 year (or longer where offered) and renewed annually.
- Owner-driver PA: a compulsory personal accident cover of ₹15 lakh for the owner-driver applies unless the owner already has qualifying PA cover of at least ₹15 lakh.
Third-party premium rates for private cars are notified by the government in consultation with IRDAI, by engine capacity, so they are the same at every insurer. Own damage premiums are priced by each insurer.
What each policy covers
| Situation | Third-party only | Comprehensive (TP + own damage) |
|---|---|---|
| You injure or kill someone in an accident | Covered (liability as decided by tribunal) | Covered |
| You damage another person's car, wall or shop | Covered, up to the property damage limit | Covered, up to the limit |
| Your own car damaged in a collision | Not covered | Covered, after deductible and depreciation |
| Car stolen | Not covered | Covered up to IDV |
| Flood, cyclone, earthquake, landslide | Not covered | Covered |
| Fire, explosion, riot, terrorism damage | Not covered | Covered |
| Owner-driver death or disability | ₹15 lakh CPA if opted | ₹15 lakh CPA if opted |
| Add-ons (zero dep, engine protect, RSA) | Not available | Available |
| No claim bonus | Not applicable | 20% to 50% off own damage premium |
Third-party death and injury liability is unlimited in law and decided by the Motor Accident Claims Tribunal; property damage cover under a standard private car policy is limited, commonly ₹7.5 lakh.
Worked example: a minor collision
Karan drives a hatchback that is two and a half years old, with an insured declared value (IDV) of ₹5,60,000 (₹8 lakh listed price less 30%). He hits another car at a signal. Damage:
- Other car's repair: ₹45,000
- Karan's own car: bumper, headlamp and bonnet, ₹70,000 (₹30,000 plastic and rubber parts, ₹25,000 metal parts, ₹15,000 labour)
With third-party only:
| Item | Insurer pays | Karan pays |
|---|---|---|
| Other car ₹45,000 | ₹45,000 | ₹0 |
| Own car ₹70,000 | ₹0 | ₹70,000 |
| Total | ₹45,000 | ₹70,000 |
With comprehensive (no zero depreciation add-on): under the standard depreciation schedule, plastic and rubber parts are depreciated 50% and metal parts on a car aged 2 to 3 years 15%; labour is not depreciated. A compulsory deductible of ₹1,000 (common for cars up to 1,500cc) applies.
| Own damage component | Bill | Depreciation | Insurer pays |
|---|---|---|---|
| Plastic and rubber parts | ₹30,000 | 50% (₹15,000) | ₹15,000 |
| Metal parts | ₹25,000 | 15% (₹3,750) | ₹21,250 |
| Labour | ₹15,000 | Nil | ₹15,000 |
| Less compulsory deductible | (₹1,000) | ||
| Own damage paid | ₹70,000 | ₹50,250 |
Karan pays ₹19,750 out of pocket for his own car and the third-party claim is paid in full. With a zero depreciation add-on, he would pay only the ₹1,000 deductible. (All figures illustrative; actual depreciation and deductibles follow the policy wording.)
He would also lose his no claim bonus at renewal, so for small repairs it is worth comparing the claim amount with the NCB you would lose.
Insured declared value (IDV)
IDV is the maximum own damage payout, roughly the car's current market value. It is the manufacturer's listed price minus depreciation by age:
| Age of car | Depreciation for IDV |
|---|---|
| Up to 6 months | 5% |
| 6 months to 1 year | 15% |
| 1 to 2 years | 20% |
| 2 to 3 years | 30% |
| 3 to 4 years | 40% |
| 4 to 5 years | 50% |
| Over 5 years | Agreed between insurer and owner |
A lower IDV reduces premium but also reduces what you get on theft or total loss. Do not cut it just to save a few hundred rupees.
When third-party alone may be enough
- The car is old (say 10+ years) and its IDV is low
- You could replace or repair it from savings without strain
- The car is rarely driven or parked in a safe, covered place
Comprehensive cover makes sense when:
- The car is new or has a high IDV
- It is on a loan; lenders generally require comprehensive cover and note their interest in the policy. See our car loan guide
- You park on the street, live in a flood-prone city, or drive long distances
A ₹70,000 repair bill is roughly 5 to 6 months of EMI on a ₹6 lakh, 5-year car loan at about 9.5%; check yours with the EMI calculator.
Standalone own damage: mixing and matching
Since September 2019, owners who already hold a valid long-term third-party policy can buy a standalone own damage policy from any insurer. This matters for new cars bought with 3-year third-party cover:
- In year 2 and year 3, the third-party part is already paid for, so you only renew own damage.
- You can switch the own damage policy to a different insurer at renewal and carry your no claim bonus with you.
- In year 4, you buy a fresh annual comprehensive policy or third-party plus standalone own damage.
Check that the third-party and own damage policy dates line up. A gap in either can mean a rejected claim, and a lapsed own damage policy may require a fresh vehicle inspection before cover restarts.
Costs and GST as of October 2026
Motor insurance premiums carry 18% GST as of October 2026. The September 2025 GST exemption applied only to individual life and health insurance, not motor. Own damage premium is reduced by your no claim bonus (20% after one claim-free year, rising to 50% after five), which you keep when you switch insurers and which belongs to you, not the car.
Claims and complaints
Report accidents to the insurer immediately, file an FIR for theft or third-party injury, and do not repair before the surveyor inspects. If a claim is rejected or under-settled, write to the insurer's Grievance Redressal Officer, then escalate through IRDAI's Bima Bharosa portal and the Insurance Ombudsman (for disputes up to ₹50 lakh). Third-party injury claims go to the Motor Accident Claims Tribunal. See insurance claim rejected reasons.
Key takeaways

- Motor premiums still carry 18% GST as of October 2026.
Frequently asked questions
Is third-party car insurance mandatory in India?
Yes. Section 146 of the Motor Vehicles Act, 1988 makes third-party liability insurance compulsory for every motor vehicle used in a public place. Comprehensive (own damage) cover is optional by law but usually required by car loan lenders.
What is the fine for driving without car insurance?
Under Section 196 of the Motor Vehicles Act as amended in 2019, driving an uninsured vehicle can attract a fine of up to ₹2,000 and/or imprisonment up to three months for a first offence, and up to ₹4,000 for a subsequent offence, as of October 2026.
Does third-party insurance cover damage to my own car?
No. Third-party insurance covers only your legal liability for death, injury or property damage caused to others. Repairs to your own car, theft and natural calamity damage need own damage cover, which comes with a comprehensive policy or a standalone own damage policy.
Can I buy own damage insurance separately?
Yes. If you already have a valid long-term third-party policy, such as the 3-year third-party cover sold with new cars, you can buy a standalone own damage policy each year from any insurer.
When is third-party insurance alone enough?
It can be enough for an old car with a low insured declared value, where the own damage premium is high relative to what a claim would pay, and you can afford to repair or replace the car yourself.
