A close friend of mine — sharp, financially savvy, the kind of person who reads the fine print on everything — bought a brand-new sedan last year. Excited about the purchase, he quickly ticked the car insurance checkbox, paid the premium, and moved on. He assumed he was covered.
Six months later, a waterlogged road during the monsoon killed his engine. The repair bill? ₹1.4 lakh.
His insurer paid exactly ₹0.
Why? Because his policy didn’t include engine protection cover. He had car insurance. He just didn’t have the right car insurance — and nobody had bothered to explain the difference.
This story isn’t unusual. Across India, millions of vehicle owners buy car insurance the same way they buy a train ticket — quickly, without much thought, just to get the thing done. And every year, thousands of them discover, at the worst possible moment, that their policy has a hole big enough to drive a car through.
I’ve spent years writing about personal finance and insurance, and if there’s one topic I keep coming back to, it’s this: car insurance is misunderstood at a scale that costs ordinary people real money. So today, I want to fix that — clearly, practically, and without the insurance industry’s love of confusing language.
The Real Purpose of Car Insurance
Before we talk about how to buy car insurance or renew car insurance smartly, let’s establish what we’re actually trying to achieve.
Car insurance exists to protect you from financial shocks you cannot absorb on your own. A minor dent is inconvenient. A total loss, a major accident claim, or a third-party lawsuit can be financially devastating. Insurance is the mechanism by which you transfer that catastrophic risk to someone else — in exchange for a predictable, manageable premium.
The problem is that most people think about it backwards. They look for the cheapest policy rather than asking: what risk am I actually trying to cover, and does this policy do that job?
That one shift in mindset — from “cheapest option” to “right coverage” — is worth more than any discount code or comparison website.
Third-Party vs. Comprehensive: The Choice That Defines Everything
If you own a car in India, you are legally required to hold at least third-party car insurance. This covers damage or injury you cause to another person or their property in an accident. It does not cover anything that happens to your own vehicle.
Comprehensive car insurance does both. It covers third-party liability and your own car — from accidents, theft, fire, floods, earthquakes, and a range of other perils. For any car that’s less than seven or eight years old, or any car you couldn’t comfortably afford to repair out of pocket, comprehensive is almost always the rational choice.
Yet a large number of Indian car owners choose third-party only — often because it’s cheaper, and because nobody explained what they were giving up.
Here’s a useful way to think about it: third-party insurance protects other people from you. Comprehensive insurance protects you from the world. Both matter. Only one is optional.
Add-Ons: Where the Real Value (and Real Confusion) Lives
Assuming you choose comprehensive car insurance, the next decision is which add-on covers to include. This is where most people either over-buy (adding everything, paying for what they don’t need) or under-buy (skipping things that would have saved them significantly).
Let me walk you through the ones that actually matter:
Zero depreciation cover is the single most valuable add-on for cars under five years old. Without it, your insurer deducts depreciation on replaced parts — meaning a three-year-old car may only receive 50–60% of the parts’ current value in a claim. With zero dep, you receive the full replacement cost. For a new or relatively new car, this add-on essentially pays for itself in one claim.
Engine protection cover is exactly what my friend needed. Standard policies exclude engine damage caused by water ingression, oil leakage, or hydrostatic lock — all of which are distressingly common during Indian monsoons. If you live in a flood-prone area or drive through waterlogged roads, this is not optional.
Roadside assistance covers towing, flat tyre help, emergency fuel, battery jump-starts, and minor on-site repairs. At typically a few hundred rupees per year, it’s one of the best value-for-money add-ons available.
Return to invoice pays you the original purchase price of your car — not the depreciated current value — if it’s stolen or written off as a total loss. This matters most in the first two to three years of ownership, when the gap between invoice price and market value is largest.
No-claim bonus protection safeguards your NCB discount even if you make one claim during the policy year. Given that NCB can be worth up to 50% off your premium after five claim-free years, losing it to a single minor claim is a painful outcome that this add-on prevents.
The right combination of add-ons depends on your car’s age, where you park, how you drive, and what you can absorb financially. Platforms like Square Insurance help you navigate this without upselling you on things you don’t need — which, in an industry full of pushy agents, is genuinely refreshing.
How to Actually Buy Car Insurance the Right Way
Here’s the step-by-step process I recommend to anyone looking to buy car insurance — whether it’s for the first time or after years of auto-renewing without thinking.
Start with your IDV. The Insured Declared Value is the current market value of your car and the maximum amount you’d receive in a total loss claim. Insurers suggest a default IDV based on depreciation tables, but you can negotiate it within a range. Don’t slash it just to lower your premium — that’s a false economy.
Compare beyond the price. Look at the insurer’s claim settlement ratio (available on the IRDAI website). A ratio above 95% is strong. Check the number of network garages for cashless repairs in your city. Read recent customer reviews specifically about claims — that’s where an insurer’s real character shows.
Choose add-ons based on your actual situation. Don’t add everything and don’t add nothing. Use the framework above: new car? Get zero dep and return to invoice. Monsoon-prone city? Get engine protection. Long highway driver? Get roadside assistance.
Apply your NCB correctly. If you have a no-claim bonus from a previous policy or insurer, make sure it’s transferred and applied. It’s your discount — you earned it.
Go digital. Buying car insurance online through a trusted platform eliminates agent commissions (which often inflate premiums), gives you a paper trail for every decision, and delivers your policy document instantly. Square Insurance does all of this in under ten minutes, with a clean interface that doesn’t bury the important decisions in small print.
The Renewal Decision: More Important Than Most People Realize
Renewing car insurance feels like a formality. It isn’t.
Renewal is your annual opportunity to reassess your coverage, update your IDV, change your add-ons, and — if your current insurer isn’t serving you well — switch to someone better. Most people miss this window because they set up auto-renewal and forget about it. That’s understandable, but it’s worth pausing once a year.
A few things to check every time you renew car insurance:
Your car is a year older, which means its IDV has changed. Make sure the updated IDV reflects your car’s actual value — not a number that was set three years ago and never revised.
Your circumstances may have changed. Did you move to a new city? Start parking on the street instead of a covered garage? Buy a dashcam? All of these affect your risk profile and potentially your optimal coverage.
Your NCB should be growing. After each claim-free year, your no-claim bonus increases — 20% after year one, up to 50% after year five. Check that your renewal quote correctly reflects your accumulated NCB.
And finally: is your insurer still good? Claim settlement ratios change year to year. Garage networks expand and contract. Customer service quality shifts. It’s worth a quick comparison at renewal time, even if you end up staying put. Square Insurance makes this comparison painless — your previous policy details are pre-loaded, and switching (or staying) takes minutes either way.
What the Insurance Industry Doesn’t Want You to Know
Here’s the uncomfortable truth: the car insurance industry in India has historically made money from customer inertia. People auto-renew without comparing. They accept default IDVs. They don’t claim their full NCB. They skip add-ons that would have made a real difference.
The digital shift is changing this — but only for people who choose to engage. The tools exist. Transparent platforms exist. Regulations requiring clear disclosure exist.
The only variable is whether you decide to spend twenty minutes a year taking your car insurance seriously. Given what’s at stake — your car, your finances, your legal standing on the road — that twenty minutes is probably the highest-return activity on your financial to-do list.
A Final Word
Go back to my friend’s story. He had car insurance. He paid his premium on time. He did everything society told him to do. And he still ended up ₹1.4 lakh out of pocket because of a gap in coverage nobody explained to him.
Don’t be that person. Whether you’re about to buy car insurance for the first time or it’s nearly time to renew car insurance on a policy you’ve barely looked at in years — take thirty minutes. Read what you’re actually covered for. Ask whether your add-ons match your real-world risks. Compare your options.
Platforms like Square Insurance exist precisely to make this process less painful, more transparent, and genuinely useful — not just a box to tick before you drive away.
Your car takes care of you every day. It’s worth taking care of the insurance that protects it.
