Your car gets you to work, school, weekend getaways, and everywhere in between. But every time you pull out of the driveway, you’re carrying a financial risk that one unexpected moment — a rear-end collision, a sudden hailstorm, a distracted pedestrian — can turn into a very costly problem. That’s precisely why car insurance isn’t just a legal checkbox. It’s one of the most important financial decisions you make as a vehicle owner.
Whether you’re looking to buy car insurance for the first time or it’s time to renew car insurance that’s been sitting on autopilot for years, this guide will walk you through everything you need to know — clearly, honestly, and without the jargon.
What Is Car Insurance, and Why Does It Actually Matter?
At its core, car insurance is a contract between you and an insurer. You pay a regular premium; in return, the insurer covers specified financial losses arising from accidents, theft, natural disasters, and third-party liability. In India, the Motor Vehicles Act makes third-party car insurance legally mandatory for every vehicle on the road — but that’s the bare minimum.
The real question isn’t whether you need car insurance. It’s whether you have the right kind.
Think about it this way: third-party insurance covers damage you cause to others. It won’t pay a rupee toward repairing your own car if you skid into a divider at 2 a.m. Comprehensive car insurance, on the other hand, covers both — your vehicle and third-party liability — and is what most financial advisors recommend for anyone with a car worth protecting.
At Square Insurance, we’ve helped thousands of drivers understand this distinction and stop paying for coverage that leaves critical gaps.
The Different Types of Car Insurance You Should Know
Before you buy car insurance, it helps to understand what’s on the table.
Third-party liability insurance is the legally mandated minimum. It covers bodily injury, death, or property damage caused to a third party in an accident where you’re at fault. It does not cover damage to your own vehicle or personal injuries sustained by you.
Comprehensive car insurance is the all-rounder. It covers third-party liability plus damage to your own car from accidents, fire, theft, floods, earthquakes, vandalism, and more. If you’re financing your car or it’s less than five years old, comprehensive is almost always the smarter choice.
Own-damage (OD) cover is a standalone policy introduced by IRDAI that covers only your own vehicle’s damage — useful if you already have a valid third-party policy and want to add self-protection separately.
Add-on covers are optional extras you can bolt onto a comprehensive policy. The most valuable ones include:
- Zero depreciation cover — ensures you receive the full cost of parts replaced, without deducting for depreciation. Highly recommended for new or premium cars.
- Roadside assistance — 24/7 help for breakdowns, flat tyres, dead batteries, and emergency towing.
- Engine protection — covers damage to your engine caused by water ingression or oil leakage, which standard policies don’t cover.
- Return to invoice — if your car is stolen or written off, this add-on pays you the original invoice value instead of the depreciated market value.
- No-claim bonus protection — safeguards your NCB even if you make a claim during the policy year.
Square Insurance offers all of these add-ons in a transparent, mix-and-match format so you only pay for what genuinely makes sense for your driving habits and vehicle age.
How to Buy Car Insurance: A Step-by-Step Breakdown
Buying car insurance has never been simpler, but there are a few decisions that significantly affect the value you get. Here’s how to approach it the right way.
Step 1: Know Your Car’s IDV
IDV — Insured Declared Value — is the current market value of your vehicle, and it determines the maximum payout you’d receive if your car is stolen or totalled. Insurers calculate IDV based on the manufacturer’s listed selling price minus depreciation. A higher IDV means higher premiums but better protection; a lower IDV saves money but leaves you underinsured.
Don’t blindly accept the default IDV suggested by an insurer. At Square Insurance, our advisors help you find the right balance.
Step 2: Compare Policies — Not Just Premiums
The cheapest policy is rarely the best one. When you compare options, look at the claim settlement ratio of the insurer, the scope of coverage, the list of network garages for cashless repairs, and the quality of customer support. A policy that saves you ₹2,000 per year but has a 40-minute claims helpline and limited garage network can cost you far more when you actually need it.
Step 3: Choose the Right Add-ons
Resist the urge to add everything — or nothing. A new car (under three years old) benefits enormously from zero depreciation and return-to-invoice cover. An older car may not need those but could benefit from a good roadside assistance plan.
Step 4: Declare Your NCB Accurately
Your No-Claim Bonus is a discount earned for claim-free years — it can be as high as 50% after five consecutive claim-free years. It’s transferable across insurers, so when you move to Square Insurance, bring your NCB certificate and make sure it’s correctly applied to your new premium.
Step 5: Complete the Purchase Online
With Square Insurance, the entire process of buying a new car insurance policy takes under ten minutes online. Upload your vehicle registration certificate, provide your previous policy details (if any), choose your coverage and add-ons, and pay securely. Your policy document is issued instantly.
When and How to Renew Car Insurance
If your policy is approaching its expiry date — or worse, has already lapsed — this section is for you.
Why You Should Never Let Your Policy Lapse
Driving without valid insurance is illegal and can result in fines, licence suspension, or both. But the financial consequences are even more serious: if you’re in an accident while uninsured, you’re personally liable for all damages — medical bills, third-party claims, and repairs to your own car.
Additionally, a lapsed policy means you lose your accumulated NCB. If you’ve built up four years of no-claim bonus, letting your policy lapse for more than 90 days wipes that discount out entirely.
How to Renew Car Insurance with Square Insurance
Renewing your car insurance through Square Insurance is designed to be frictionless. Here’s what the process looks like:
1. Start early. Don’t wait until the last day. Begin the renewal process at least two weeks before expiry to have time for an inspection if required (mandatory for policies lapsed beyond 90 days).
2. Review your current coverage. Renewal is the perfect moment to reassess your add-ons, update your IDV, or switch from third-party to comprehensive. Your needs in year four of ownership are different from year one.
3. Get your renewal quote. Log in to the Square Insurance portal or app, enter your policy number or vehicle registration number, and your renewal quote is generated instantly. All your previous details are pre-filled.
4. Make adjustments. Change your add-ons, adjust the IDV, apply your NCB — then confirm.
5. Pay and receive your updated policy. Payment is processed securely. Your renewed policy document arrives in your inbox within minutes, and physical copies can be requested if needed.
Common Car Insurance Mistakes to Avoid
Even experienced car owners make these errors. Check yourself against this list.
Not reading the exclusions. Every policy has conditions under which claims won’t be paid — driving under the influence, using a personal car for commercial purposes, or damage caused by wear and tear. Know your exclusions before you need to make a claim.
Under-insuring to save on premiums. Setting a very low IDV reduces your premium but means you’ll receive far less than your car’s actual value if it’s written off. The short-term saving is rarely worth the long-term risk.
Forgetting to update your policy after modifications. If you’ve installed a CNG kit, a new audio system, or any other modification, inform your insurer. Undisclosed modifications can lead to claim rejection.
Not comparing at renewal. Loyalty doesn’t always pay in insurance. The market is competitive, and Square Insurance encourages you to compare — you may find better coverage at the same or lower premium by switching.
