Things to Check Before Buying Car Insurance in India: A Complete Buyer’s Guide (2026)
Car insurance: Third-party liability cover is mandatory in India, but most buyers overpay or under-insure by skipping checks on IDV, add-ons, and claim settlement ratios before signing up.
Cracking Your Car Insurance Code: What Every Indian Car Owner Must Check Before Buying in 2026
Car Insurance: Buying car insurance in India is not just a compliance exercise to satisfy the Motor Vehicles Act — it is a financial decision that determines how well you are protected the day something goes wrong. Every year, thousands of car owners renew policies on auto-pilot, picking whatever the dealer bundles in or whatever pops up first on a comparison website, without checking IDV, add-ons, exclusions, or claim settlement track record.
This guide is meant to change that. As an independent publication, we have no commercial tie-up with any insurer, broker, or aggregator featured or referenced here — the goal is simply to help you buy the right cover, not the cheapest-looking one.
Car Insurance: Why Car Insurance Is Not Optional in India
Third-party car insurance is mandatory under Section 146 of the Motor Vehicles Act, 1988. Driving without it is a punishable offence, and more importantly, it leaves you personally liable for the entire cost of injury, death, or property damage caused to a third party in an accident — a liability that can run into lakhs or crores of rupees with no upper cap on personal injury claims.
A comprehensive policy goes further, also covering damage to your own vehicle from accidents, fire, theft, and natural calamities. Given how central owning a car has become for Indian households, and how unpredictable Indian roads are, treating insurance as a checkbox rather than a shield is one of the most common and costly financial mistakes car owners make.
1. Third-Party vs Comprehensive vs Standalone Own-Damage: Know What You’re Actually Buying
There are three broad structures in the Indian car insurance market, and confusing them is the single biggest buyer error.
Third-party (liability-only) insurance covers only the other party’s losses — injury, death, or property damage you cause to someone else. It does not pay a rupee for damage to your own car. The premium for this is fixed by IRDAI and is identical across every insurer, so there is no “discount” to chase here; the only real choice is who you buy it from and how efficiently they process claims when needed.
Comprehensive insurance bundles third-party liability with own-damage (OD) cover, protecting your own vehicle against accidents, fire, theft, natural disasters (flood, earthquake, cyclone), and man-made disasters (riots, strikes, vandalism). This is the default recommendation for most car owners, especially anyone still paying off a car loan, since most lenders mandate comprehensive cover until the loan is closed.
Standalone own-damage (OD) insurance is a newer, less-known option. It lets you buy only the own-damage component separately from an insurer of your choice, while your existing long-term third-party policy (bought at the time of purchase) continues elsewhere. This can occasionally work out cheaper for owners whose long-term TP cover still has time left, but it requires careful comparison, since the pricing advantage isn’t guaranteed and varies by insurer and vehicle profile.
2. Car Insurance: Get the Insured Declared Value (IDV) Right
The IDV is the maximum sum your insurer will pay if your car is stolen or damaged beyond repair — effectively, the current market value of your car as assessed by the insurer, after factoring in depreciation. This is where many buyers unknowingly lose money on both ends.
If the IDV is set too low, your premium looks attractively cheap, but you will be significantly underpaid in a total loss claim. If it’s set unrealistically high, you pay a higher premium than necessary for coverage you’ll never fully realise, since the insurer will still apply depreciation-based settlement norms. The sensible approach is to let the IDV reflect a fair, realistic market value of the car — most insurers auto-calculate this based on the manufacturer’s listed selling price adjusted for depreciation and age, but it is worth checking and, where allowed, negotiating this figure rather than accepting it blindly, especially at renewal time when depreciation should have already reduced it.
3. Car Insurance: No-Claim Bonus (NCB): Don’t Let It Lapse
NCB is a discount on your own-damage premium, awarded for every claim-free year, and it can compound to a meaningful percentage over several years of safe driving. It rewards you, the driver, not the vehicle — which means NCB is transferable if you sell your car and buy a new one, provided you complete the transfer paperwork with your insurer within the specified window.
The mistake to avoid: filing a small claim for minor damage just because you can, and resetting your NCB in the process. For low-value repairs, it is often financially smarter to pay out of pocket and preserve your accumulated NCB, since a single claim can wipe out years of accumulated discount. Before renewal, always confirm your current NCB slab is correctly reflected — insurers occasionally miss updating it, and it is on you to flag the discrepancy.
4. Choose Add-Ons Based on Real Risk, Not Habit
Add-ons increase your premium but can meaningfully change your claim experience. The commonly available ones in the Indian market include zero depreciation cover (waives depreciation deduction on parts during claim settlement), engine protection cover (useful in flood-prone or waterlogging-heavy cities), roadside assistance, return-to-invoice cover (pays the original invoice value, not depreciated IDV, in case of total loss or theft — particularly relevant in the first 2–3 years of ownership), consumables cover, and NCB protection (lets you make one claim without losing your NCB).
Not every add-on is worth it for every owner. Zero depreciation and engine protection make more sense for owners in cities with heavy monsoon flooding or dense traffic; return-to-invoice is more relevant for a car in its first few years than one nearing the end of its resale life. Buying every add-on indiscriminately inflates premiums without proportionate benefit — the right approach is to map add-ons to your specific driving pattern, city, and car age.
5. Understand the Deductible Structure
A deductible is the portion of a claim you pay out of pocket before the insurer covers the rest. There are two kinds: a compulsory deductible, fixed by IRDAI based on your car’s engine capacity, and a voluntary deductible, which you can opt to increase in exchange for a lower premium.
Opting for a higher voluntary deductible can meaningfully cut your premium, but only makes sense if you are confident you won’t need to make frequent small claims and can comfortably absorb a larger out-of-pocket cost when you do need to claim. This is a genuine trade-off, not a one-size-fits-all decision, and should be based on your own risk appetite and claims history.

6. Car Insurance: Check the Insurer’s Claim Settlement Ratio and Network Garages
A policy is only as good as the claim experience behind it. Before buying, it is worth checking an insurer’s claim settlement ratio (the percentage of claims settled against claims received in a financial year), which IRDAI publishes periodically in its annual report. A high ratio is a reasonable proxy for reliability, though it should be read alongside the insurer’s network of cashless garages in your city, since cashless settlement at a nearby, quality garage matters far more in practice than a headline discount at the time of purchase.
7. Don’t Ignore the Fine Print on Exclusions
Every policy has standard exclusions: normal wear and tear, mechanical or electrical breakdown (unless specifically covered), consequential damage, driving without a valid licence, driving under the influence, and use of the vehicle for purposes other than what’s declared (for instance, using a private car for commercial ride-hailing without informing the insurer). Claims are commonly rejected not because of fraud, but because a policyholder simply didn’t read what was excluded. Reading the policy wording — not just the sales brochure — before buying is a genuinely useful five minutes.
8. Car Insurance: Compare Before You Renew, Not Just Before You Buy
Car insurance shopping usually gets serious attention at the time of a new car purchase and then goes on autopilot at every renewal. This is a mistake. Insurer pricing on the own-damage component varies, network garages change, and new add-ons or better claim processes may become available. It’s worth treating every renewal as a fresh comparison exercise rather than a formality, particularly since IRDAI has, in recent years, been recalibrating third-party premium rates upward in line with rising claim costs — meaning your renewal premium this year may reportedly differ meaningfully from last year’s, regardless of which insurer you choose for the third-party component.

9. Understand How Premiums Are Actually Calculated
Car insurance premiums in India are a function of several factors working together: the vehicle’s engine capacity or, for electric vehicles, motor power output in kilowatts; the car’s age and IDV; the city of registration (since claim frequency varies by region); the owner’s NCB slab; add-ons selected; and, for the third-party component, the IRDAI-notified rate applicable to that vehicle category. Because the third-party premium is regulated and identical across insurers, real price competition in the Indian market happens almost entirely on the own-damage component and on service quality — which is exactly where comparison shopping adds value.
10. Electric Vehicles Need a Slightly Different Lens
EV insurance works on similar principles but with a few practical differences worth flagging: third-party premiums for EVs are calculated based on kilowatt (kW) motor output rather than engine cc, and several insurers now offer EV-specific add-ons covering the battery and charging equipment. Given that battery replacement costs form a disproportionate share of an EV’s total value, checking whether battery cover is included — or needs to be added separately — is worth a specific look for EV owners.

Frequently Asked Questions
Is car insurance mandatory in India?
Yes. Third-party car insurance is a legal requirement under the Motor Vehicles Act, 1988, and driving without valid third-party cover is a punishable offence. Comprehensive cover, which also protects your own vehicle, is optional but strongly recommended.
What is the difference between third-party and comprehensive insurance?
Third-party insurance covers only damage or injury you cause to another person or their property. Comprehensive insurance covers that plus damage to your own vehicle from accidents, theft, fire, and natural disasters.
Can I change my insurer at renewal?
Yes. There is no requirement to renew with the same insurer, and comparing quotes at renewal — particularly for the own-damage component — can uncover better pricing or service than sticking with the incumbent by default.
Does my No-Claim Bonus carry over if I buy a new car?
Yes. NCB is linked to the policyholder, not the vehicle, and can be transferred to a new car’s policy as long as the transfer is completed within the timeline specified by the insurer.
Should I file a claim for minor damage?
Not always. For small, low-value repairs, paying out of pocket often works out cheaper than losing your accumulated NCB, which reduces your premium discount for future years.
What happens if my IDV is set too low?
You will receive a lower payout than your car’s actual worth in the event of theft or total loss, even though your premium was correspondingly cheaper — an unfavourable trade-off in the event you actually need to claim.
Are add-ons worth the extra premium?
It depends on your specific situation. Add-ons like zero depreciation or engine protection are genuinely useful for owners in flood-prone cities or with newer cars, but stacking every available add-on regardless of relevance simply inflates the premium without proportionate benefit.
How is the third-party premium decided?
It is fixed by IRDAI based on the vehicle’s engine capacity (or motor power for EVs) and is uniform across all insurers; it is periodically revised in consultation with the Ministry of Road Transport and Highways.
Is standalone own-damage insurance a good idea?
It can be, for owners whose existing long-term third-party cover still has validity left, but the cost-benefit depends on individual insurer pricing and should be compared rather than assumed.
What should I check before buying, beyond price?
The insurer’s claim settlement ratio, its network of cashless garages in your city, the exact policy wording on exclusions, and whether the IDV and NCB reflected are accurate — price alone is a poor proxy for the quality of cover.
