Third-party (TP) insurance is mandatory by law under the Motor Vehicles Act, 1988 — driving without it is a criminal offence. It covers injuries and property damage you cause to others, but pays nothing for your own vehicle. Comprehensive insurance adds own-damage (OD) cover — protecting your car from accidents, theft, fire and natural disasters. For any car worth more than a few lakh rupees, comprehensive cover is almost always the financially sensible choice.
Third-party vs. comprehensive: what each covers
| Coverage | Third-party only | Comprehensive |
|---|---|---|
| Third-party bodily injury liability | Yes | Yes |
| Third-party property damage (up to ₹7.5 lakh) | Yes | Yes |
| Your own car — accident damage | No | Yes |
| Your own car — theft | No | Yes |
| Your own car — fire / explosion | No | Yes |
| Natural disasters (flood, earthquake, cyclone) | No | Yes (OD component) |
| Personal accident cover (driver) | ₹15 lakh mandatory PA cover (separate) | Included or bundled |
| Add-ons (zero dep, engine protect, etc.) | Not available | Available |
| IRDAI-regulated premium | Yes — fixed tariff | TP portion fixed; OD market-priced |
Why third-party insurance is mandatory
The Motor Vehicles Act, 1988 makes third-party motor insurance compulsory for every vehicle used on public roads in India — no exceptions. The law exists to ensure victims of road accidents can receive compensation regardless of the at-fault driver's ability to pay. The Motor Accidents Claims Tribunal (MACT) processes claims from injured third parties against insured vehicles.
IRDAI sets the third-party premium tariff centrally. As of 2025–2026, annual TP premiums for private cars are: ₹2,094 for engines under 1,000 cc; ₹3,416 for 1,000–1,500 cc; and ₹7,899 for engines over 1,500 cc. These figures were revised upward by approximately 15–20% in April 2025, with a further hike of 10–25% expected in FY 2026–27.
What third-party insurance does not cover
The coverage gap in a TP-only policy is significant. If you are involved in an accident that damages your own car — even if a third party was at fault and they are uninsured — a TP policy pays you nothing. The same applies to:
- Theft of your vehicle
- Fire, explosion or self-ignition damage
- Damage from floods, cyclones, earthquakes or other natural disasters
- Vandalism or malicious damage
- Any own-damage scenario where you bear fault
India has roughly 20 crore registered motor vehicles (2025 estimate) with a significant proportion uninsured or lapsed. An accident with an uninsured third party leaves a TP-only holder with no recourse for their own vehicle repairs.
Comprehensive insurance: what the OD component adds
A comprehensive policy combines mandatory third-party cover with an 'own damage' (OD) section that covers your vehicle. The OD premium is market-priced by each insurer (unlike the tariffed TP component) and calculated primarily on the vehicle's Insured Declared Value (IDV).
IDV is the car's current market value — effectively what the insurer would pay in a total loss. IRDAI sets standard depreciation rates by vehicle age: new cars depreciate 5% in year one, reaching 50% depreciation by year five. Opting for a higher IDV means a higher premium but better protection in a total loss or theft.
Since 2018, IRDAI has mandated that new private cars must be sold with a 3-year third-party policy (and new two-wheelers with a 5-year TP policy). The own-damage component can be taken annually alongside the bundled TP. This means new car buyers have locked-in TP coverage for three years but need to renew OD cover annually.
When is third-party only appropriate?
TP-only cover makes practical sense in a narrow set of circumstances:
- The vehicle is very old (5+ years) and has depreciated to a low IDV where the annual OD premium is disproportionate to the car's market value.
- The vehicle is rarely driven and stored securely, minimising own-damage risk.
- The owner has sufficient liquid reserves to self-insure own-damage losses.
For any car under five years old or with a significant IDV, skipping OD cover is false economy. A single accident requiring major bodywork can cost ₹50,000–₹2,00,000 or more — far exceeding years of OD premiums.
Key add-ons available only with comprehensive cover
The full range of insurance add-ons is available only on comprehensive policies:
- Zero depreciation: insurer pays full part-replacement cost without deducting depreciation. Highly recommended for cars under 5 years old.
- Engine protect: covers engine damage from water ingress or lubricant leakage — particularly relevant in flood-prone regions.
- Return to invoice: in a total loss, the insurer pays the original invoice value rather than the depreciated IDV.
- Roadside assistance: towing, fuel delivery, battery jumpstart.
- NCB protect: preserves no-claims bonus despite a claim.
