Third-party vs comprehensive, IDV explained, No Claim Bonus, Zero Depreciation and other add-ons that actually matter, and exactly what to do when you need to claim — everything an Indian vehicle owner needs in one place.
Under the Motor Vehicles Act, driving any vehicle on Indian roads without at least third-party insurance is a punishable offence — with fines and potential licence suspension on repeat violations. But the legal requirement is really the floor, not the goal. Third-party insurance protects others from the financial consequences of an accident you cause; it does nothing for your own vehicle.
A comprehensive motor policy adds "own-damage" cover — for your vehicle's repairs after an accident, plus protection against theft, fire, natural calamities (floods, cyclones, earthquakes) and man-made events (riots, vandalism). Given that vehicles are often a family's second-largest asset after a home, and repair costs for modern cars (with sensors, cameras and complex electronics) have risen sharply, comprehensive cover is rarely optional in practice — even though it's not legally mandatory.
This guide walks through every major decision you'll make when buying, renewing, or claiming on motor insurance — for both cars and two-wheelers.
There are really three policy structures available in India today — here's how they differ.
Covers legal liability for injury, death, or property damage caused to a third party (another person, vehicle or property). It is the legal minimum. Premiums are fixed annually by IRDAI/the government based on engine/cubic capacity, so they're identical across insurers.
Best for: Legal compliance only — rarely sufficient on its own for owned vehiclesCombines third-party liability with own-damage cover for your vehicle — accidents, theft, fire, natural and man-made calamities. This is what most people mean by "full" motor insurance, and where add-ons like Zero Depreciation apply.
Best for: Almost every vehicle owner, especially newer or higher-value vehiclesCovers only your vehicle's own damage — used when you already have a separate, valid multi-year third-party policy (common for new vehicles, which often come with a 3-5 year mandatory TP cover bundled at purchase).
Best for: New vehicle owners whose multi-year TP policy is still active and need to insure own-damage separatelyCollision, overturning, or external impact to your vehicle
Damage from fire, self-ignition or explosion
Total loss of the vehicle due to theft
Flood, cyclone, earthquake, landslide, etc.
Riots, strikes, malicious acts, vandalism
Damage during transport by road, rail, air or sea
Mandatory PA cover for the owner-driver (₹15 lakh standard)
Unlimited for death/injury, capped for property damage
The IDV is the maximum sum your insurer will pay in case of theft or a "total loss" (where repair cost exceeds a certain percentage of the vehicle's value, or it's beyond economical repair). It's essentially the agreed current market value of your vehicle, calculated as the manufacturer's listed selling price minus depreciation based on the vehicle's age — adjusted for any registered accessories.
| Vehicle Age | Depreciation for IDV |
|---|---|
| Up to 6 months | 5% |
| 6 months - 1 year | 15% |
| 1 - 2 years | 20% |
| 2 - 3 years | 30% |
| 3 - 4 years | 40% |
| 4 - 5 years | 50% |
| Over 5 years | Mutually agreed between insurer and owner |
Some owners deliberately set a lower-than-default IDV (most insurers allow a range, typically -15% to the standard figure) to reduce the premium slightly. This is usually a false economy: if your vehicle is stolen or written off, you'll receive this lower amount — potentially tens of thousands of rupees less — for a premium saving that's often just a few hundred to a couple of thousand rupees. We generally recommend sticking to the insurer's standard (default) IDV unless you have a specific reason not to.
No Claim Bonus is a discount on your own-damage premium for every consecutive claim-free policy year. It does not apply to the third-party premium component, but on the own-damage portion the savings compound quickly:
| Claim-Free Years | NCB Discount |
|---|---|
| 1 year | 20% |
| 2 years | 25% |
| 3 years | 35% |
| 4 years | 45% |
| 5 years | 50% (maximum) |
A handful of add-ons account for most of the value in a good motor policy. Here are the ones we most often recommend.
No deduction for depreciation on parts during claim settlement
Keep your No Claim Bonus even after 1-2 claims in a year
Towing, fuel delivery, flat tyre & battery jump-start, 24x7
Covers engine damage from water ingress (hydrostatic lock) — crucial in flood-prone cities
In a total loss, get the original invoice value, not just the depreciated IDV
Covers cost of replacing lost or stolen keys and locks
Covers nuts, bolts, oil, lubricants etc. often excluded otherwise
For electric vehicles — covers high-cost battery and charger damage
For electric vehicle owners specifically, see our dedicated guide: Electric Vehicle Insurance in India.
Here's the process we walk every client through.
Comprehensive for most owned vehicles; SAOD if your TP cover is still valid.
Stick to the insurer's default unless you have a specific reason to adjust it.
Get your NCB certificate from the previous insurer before switching.
Zero-Dep and RSA are the most commonly useful for most owners.
We compare network garage coverage and claim experience, not just premium.
Check registration number, engine/chassis number and IDV are correct.
A lapsed policy means driving illegally and risking your NCB.
