Car insurance is a contract between you and an insurer where you pay an annual premium in exchange for financial protection against accidents, theft, fire, natural calamities, and third-party liabilities. Under the Motor Vehicles Act, 1988, driving without at least basic third-party cover is illegal in India — but the real value of insurance goes well beyond staying compliant. A single accident repair bill or a total-loss claim can run into lakhs, and the right policy is what keeps that cost off your own pocket.
Types of Car Insurance Policies in India
Car insurance isn’t one-size-fits-all. Three broad policy types are available, and picking the right one depends on your car’s age, usage, and whether it’s financed.
Third-Party Car Insurance
This is the legal minimum every car owner must carry. It covers injury, death, or property damage you cause to another person or vehicle — but nothing on your own car. Premiums for third-party cover are fixed annually by IRDAI, so they’re identical across insurers for a given engine capacity.
Comprehensive Car Insurance
Comprehensive cover combines third-party liability with own-damage (OD) protection, covering your own vehicle against collisions, theft, fire, riots, and natural disasters. Most financed cars are required to carry this by the lender, and most owners choose it regardless since it’s the only cover that protects the vehicle itself.
Standalone Own-Damage Cover
If you already have an active third-party policy — common for cars past their initial long-term TP tenure — you can buy a separate OD-only policy to cover just your own vehicle’s damage.
| Cover Type | Own Car Damage | Third-Party Liability | Legally Mandatory |
| Third-Party Only | No | Yes | Yes |
| Comprehensive | Yes | Yes | No, but widely preferred |
| Standalone OD | Yes | No (needs active TP separately) | No |
Third-Party Premium Rates as Set by IRDAI
Since third-party premiums are regulated rather than insurer-set, they vary only by engine capacity, not by which company you buy from:
| Engine Capacity | Annual TP Premium (approx.) |
| Below 1000cc | ₹2,094 |
| 1000cc–1500cc | ₹3,416 |
| Above 1500cc | ₹7,897 |
Comprehensive premiums, on the other hand, vary meaningfully between insurers based on their own-damage pricing model, claim history, and add-on rates — which is exactly why comparing quotes actually matters for OD cover, even though it doesn’t for third-party alone.
Understanding Insured Declared Value (IDV)
IDV is the maximum amount your insurer pays if your car is stolen or damaged beyond economical repair. It’s essentially your car’s current market value, calculated by applying standard depreciation to the ex-showroom price.
| Vehicle Age | Depreciation Applied to 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% |
| Above 5 years | Based on insurer assessment |
A lower IDV brings your premium down but also caps your payout in a total-loss claim — so it’s worth setting deliberately at renewal rather than accepting whatever the platform defaults to.
How to Buy Car Insurance Online
Buying online has largely replaced branch visits, and doing it right comes down to a handful of careful steps:
Step 1 — Choose your cover type. New or financed cars should default to comprehensive; older, low-value cars may only need third-party.
Step 2 — Enter accurate vehicle details. Registration number, make, model, variant, and registration date all feed directly into your premium and IDV calculation — errors here can delay or jeopardise a future claim.
Step 3 — Compare quotes across insurers. For the same comprehensive cover, premiums can differ by a few thousand rupees between insurers depending on their claim settlement track record and garage network. Platforms like Square Insurance pull quotes from multiple IRDAI-licensed insurers in one place, so you’re not opening a dozen separate insurer sites to compare.
Step 4 — Pick add-ons based on your actual driving profile, not whatever’s pre-selected by default.
Step 5 — Pay and download the policy copy, and cross-check the IDV, registration number, and selected add-ons on the PDF before closing out.
Add-On Covers Worth Knowing
Add-ons let you tailor a comprehensive policy to your real risk exposure rather than paying for blanket protection you’ll never use.
| Add-On | What It Does | Best Suited For |
| Zero Depreciation | Removes wear-and-tear deduction on parts during a claim | New cars, first 3–4 years |
| Engine Protect | Covers engine damage from water ingress or oil leakage | Flood-prone or coastal cities |
| Roadside Assistance | Towing, on-spot repair, fuel delivery | Frequent highway/long-distance drivers |
| Return to Invoice | Pays invoice value instead of depreciated IDV on total loss/theft | New or high-value financed cars |
| NCB Protect | Preserves your No Claim Bonus even after one claim | Regular city drivers with claim risk |
| Consumables Cover | Pays for nuts, bolts, engine oil, coolant during repair | Anyone wanting to avoid small out-of-pocket repair costs |
Zero dep and engine protect tend to offer the most value relative to their cost, while things like roadside assistance are worth skipping if you rarely drive outside city limits.
No Claim Bonus (NCB): The Most Underused Discount
NCB rewards claim-free years with a discount on your own-damage premium — and it’s one of the easiest ways to cut renewal costs that most people simply forget to leverage properly.
| Consecutive Claim-Free Years | NCB Discount |
| 1 year | 20% |
| 2 years | 25% |
| 3 years | 35% |
| 4 years | 45% |
| 5+ years | 50% |
NCB belongs to you, not the vehicle. If you sell your car and buy a new one, request an NCB retention certificate from your outgoing insurer before the policy lapses — skip this step and you start from zero on the new car, even with a spotless claim record.
How to Renew Your Car Insurance Policy
Renewal is where a lot of policyholders unknowingly lose money on their car insurance renewal, either by letting NCB lapse or by auto-renewing without comparing options.
A long lapse can trigger a fresh inspection. If your comprehensive policy stays lapsed too long, insurers may require a vehicle inspection before reissuing cover, and your accumulated NCB can reset.
Treat renewal as a comparison checkpoint, not a formality. Premiums and add-on pricing shift every year — running a quick comparison through an aggregator like Square Insurance at renewal time often surfaces meaningfully better pricing for the same coverage.
Revisit your IDV. Your car depreciates every year; the IDV on your renewed policy should reflect that rather than staying frozen at last year’s figure.
Filing a Car Insurance Claim
How smoothly a claim goes usually comes down to what you do in the first hour after an incident, not what happens afterward.
Cashless Claims
When repairs happen at a network garage, the insurer settles directly with the garage (minus your deductible). This is faster and involves far less paperwork on your end — but you need to inform the insurer promptly, typically within 24–48 hours.
Reimbursement Claims
If you use a non-network garage, you pay upfront and file for reimbursement afterward with bills and invoices. This route takes longer and puts the documentation burden entirely on you.
Claim Filing Checklist
- Notify your insurer or call the claims helpline immediately
- Photograph the damage and accident scene before moving the vehicle
- File an FIR for theft, major accidents, or any third-party injury
- Wait for a surveyor inspection before starting repairs, if your insurer requires one
- Keep the RC, driving license, and policy copy ready when filing
Documents Typically Required
- Duly filled and signed claim form
- Policy copy and previous year’s policy details (for NCB verification)
- Driving license and RC copy
- FIR copy, for theft or major accident cases
- Original repair bills and payment receipts
Common Mistakes to Avoid
- Chasing the lowest premium while ignoring claim settlement ratio and garage network strength
- Mis-declaring IDV, either too low to save premium or unrealistically high with no real benefit
- Skipping zero depreciation on a new car, then absorbing steep deductions at claim time
- Letting a policy lapse and losing years of accumulated NCB in one missed renewal
- Admitting fault at the accident spot before the insurer or surveyor has assessed the situation
- Starting repairs before inspection, which can jeopardise the claim entirely
- Not reading exclusions — most policies exclude claims involving an invalid license, drunk driving, or commercial use of a privately insured vehicle
Final Word
A good car insurance policy isn’t the one with the lowest number on the quote page — it’s the one that actually pays out cleanly when you need it to. That comes down to three things done right: an IDV that reflects your car’s real value, add-ons matched to how and where you actually drive, and an insurer with a genuinely strong claim settlement record. Comparing these properly, instead of defaulting to whatever loads first, is a ten-minute exercise that can save both money and a lot of frustration down the line.
