Third-party car insurance is the legal minimum, but is it enough? This guide explains exactly what comprehensive and third-party policies each cover, how IRDAI regulates third-party premiums, the real cost difference, how No Claim Bonus works, and when each cover type makes sense for your car.

Third-party (TP) insurance is the legal minimum mandated by Section 146 of the Motor Vehicles Act, 1988. It protects you against financial liability if your vehicle injures another person, causes a fatality, or damages someone else's property — the Motor Accidents Claims Tribunal can award compensation in lakhs. What TP does not cover is your own car: if you damage your own vehicle, or it is stolen or hit by a falling tree, a TP policy pays nothing.
TP premium is set by IRDAI each year and is identical across all insurers. For 2024-25, cars up to 1000cc pay ₹2,094/year, 1000–1500cc pay ₹3,416/year, and above 1500cc pay ₹7,897/year.
A comprehensive policy combines third-party liability with own-damage (OD) cover — protecting your car against accidents, fire, theft, floods, cyclones, vandalism and riots. It also unlocks add-ons that TP never offers, such as zero depreciation, engine protection, roadside assistance and NCB protection. The OD premium is not regulated by IRDAI; it is calculated as a percentage of your IDV, so a higher-value car pays more.
For a small hatchback, standalone TP costs ₹2,094/year while comprehensive might run ₹8,000–₹12,000/year depending on insurer and add-ons — the difference is the cost of protecting your own car. No Claim Bonus (NCB) can cut the OD portion by up to 50% over five claim-free years:
NCB applies only to the OD portion — the TP component is always the full IRDAI-regulated rate.
Choose TP-only when your car is very old (10+ years) with low market value, where the OD premium approaches the maximum claim you could receive. Choose comprehensive when the car is new or under seven years old, financed, high-value, or parked in a flood- or theft-prone area. A middle path is a standalone OD policy (permitted since 2019) that lets you switch OD insurers independently. For the wider picture, read the car insurance guide.
No, it is not advisable for a new car. Third-party insurance does not cover any damage to your own vehicle. If a new car is damaged in an accident or stolen, you bear the entire cost. For any car under five years old, comprehensive is strongly recommended, and a financed car requires it.
IRDAI mandates uniform third-party premium rates across all insurers to prevent competitive undercutting that could leave accident victims uncompensated. The rates are reviewed and revised annually based on actuarial claims data from across India.
Introduced by IRDAI in September 2019, a standalone OD policy covers only your own vehicle's damage — not third-party liability. You must hold a separate TP policy to be road-legal. It lets you shop for the best OD rate independently each year.
Yes. At renewal you can drop the OD component and keep only TP cover. However, you lose your NCB, which applies only to the OD portion, and you cannot carry it forward unless you maintain continuous comprehensive coverage.
No. Your own TP policy never pays for your car's damage, even if the other driver is at fault. You can claim against the at-fault driver's TP insurer, but recovering money through the Motor Accidents Claims Tribunal can take months or years — which is why comprehensive cover is recommended.
