Motor insurance in India: a cover, IDV and NCB buying checklist

Begin with the cover, not the cheapest premium

Motor insurance quotations are difficult to compare when the headline price hides a lower Insured Declared Value, a larger deductible or missing own-damage protection. The Insurance Regulatory and Development Authority of India (IRDAI) states that third-party liability cover is mandatory for vehicles using public roads. Protection for damage to your own vehicle is a separate buying decision and may be provided through a package, bundled or standalone own-damage arrangement as applicable.

This guide is educational, not a recommendation for an insurer or policy. Policy wording, eligibility and prices change. Read the current policy schedule and product wording before payment.

Understand the four building blocks

Third-party liability

This responds to covered liability for injury or damage caused to other people or property. It does not by itself pay to repair your own vehicle after an at-fault collision, flood or theft. Do not call a liability-only quotation “comprehensive”.

Own-damage cover

Own-damage cover protects the insured vehicle against events defined by the policy. Exclusions, depreciation, deductibles and claim procedure matter. Compare coverage, not merely the policy label.

Personal accident and other required elements

Check the schedule for compulsory or selected personal-accident protection and verify whether the owner-driver is eligible. Do not pay twice for cover that is already valid elsewhere without checking the applicable rules and declarations.

Add-ons

Add-ons extend the base cover for an extra premium. Common names include nil depreciation, return to invoice and no-claim-bonus protection, but names are not standard proof of identical coverage. Read the trigger, exclusions, number of claims allowed, vehicle-age limit and settlement basis.

Compare IDV on the same basis

IRDAI describes IDV as the sum insured for the vehicle and says it should reflect current market value. A lower IDV can reduce premium while also reducing the insured amount used for certain total-loss or theft settlements. A high IDV is not automatically better if it is unsupported or priced poorly.

Put each quotation in a table with:

• vehicle and variant exactly as registered;
• IDV;
• third-party premium;
• own-damage premium;
• compulsory and voluntary deductibles;
• add-ons and their individual cost;
• taxes;
• cashless network relevant to your location;
• total payable premium.

Reject a comparison that shows only the final price.

Deductibles change the real cost of a claim

A deductible or excess is the portion you bear before the insurer pays the covered balance. Policies can contain a compulsory amount and an optional voluntary amount. Choosing a larger voluntary deductible may reduce premium but raises your out-of-pocket cost for every applicable claim.

Test the quotation with two scenarios: a modest repair and a major repair. Include depreciation, consumables and deductible treatment based on the actual policy wording. This exposes an apparently cheap policy that transfers too much routine loss back to you.

No-claim bonus belongs to the policyholder

IRDAI’s policyholder guidance explains that no-claim bonus applies to the own-damage premium, progresses with eligible claim-free years and belongs to the insured person rather than the vehicle. It can generally be carried to another insurer at renewal with appropriate proof.

Check the declared NCB percentage. An incorrect NCB declaration can create trouble during a claim. When selling a vehicle, preserve the insurer’s NCB evidence if you plan to use the benefit for a replacement vehicle.

New-vehicle policy periods need careful reading

IRDAI distinguishes the duration of third-party and own-damage components for new private cars and new two-wheelers. A bundled policy can therefore contain components that expire on different dates. Put both dates in your calendar and verify the current regulatory arrangement for your vehicle class.

Approach renewal before expiry. A break can require inspection and can leave you exposed while the policy is inactive.

Disclose modifications and usage honestly

Registration details, vehicle class, engine or chassis information, seating or carrying capacity and claim history can affect underwriting. Inform the insurer about material changes. IRDAI specifically advises informing the registering authority and insurer when an approved CNG or LPG kit is fitted, so the registration and policy can be updated.

Also disclose commercial use, accessories and address changes where required. A private-car policy should not be assumed to cover a different declared use.

Claims service questions to ask before purchase

1. Which authorised or cashless workshops are available near home and regular travel routes?
2. Who must be contacted first after an accident or theft?
3. Is inspection required before repair begins?
4. Which documents are required for cashless and reimbursement claims?
5. How are towing, consumables, keys and depreciation handled?
6. What are the time limits for notice and document submission?
7. How are complaints escalated inside the insurer and to the regulator’s grievance system?

Save the policy PDF, schedule, payment receipt, proposal answers and inspection media outside the vehicle as well as in an accessible digital location.

Renewal checklist

• Match registration, owner name, address, engine and chassis details.
• Confirm liability and own-damage start and end dates separately.
• Verify IDV against current value and competing quotes.
• Confirm NCB using the expiring policy or renewal notice.
• Compare like-for-like deductibles and add-ons.
• Confirm a valid PUC where required for renewal.
• Remove add-ons that no longer apply, and do not assume an old add-on continues automatically.
• Pay only through the insurer or an authorised channel and verify the issued policy.

Used-vehicle transfer is time-sensitive

When a vehicle changes owner, registration and insurance should be aligned. IRDAI’s guidance says the seller should inform the insurer and notes a limited period for recording transfer in comprehensive or package policies for own-damage claims. Do not drive for weeks relying on a policy that still names the seller. Ask the insurer for the exact transfer documents and effective date.

The responsible conclusion

The strongest insurance comparison holds coverage constant and then compares price. Start with mandatory liability, choose an appropriate own-damage structure, compare IDV and deductibles, validate NCB and read every add-on. Current policy wording and the issued schedule override summaries on a comparison screen.
