From 15 December 2026, private-car and two-wheeler motor policies are scheduled to move to a clearer four-layer format directed by the Insurance Regulatory and Development Authority of India (IRDAI). The practical change is not a promise of one cheaper premium: it is a requirement to show third-party, occupant or pillion, personal-accident and own-damage protection separately so the owner can see what is included and what is optional.
This guide explains how the four layers fit together, how to read the option form and Customer Information Sheet, and what to check at renewal. For the dated announcement, see the IRDAI four-layer motor-insurance update; the guide below focuses on the lasting decision and document checks.
Key takeaways
- Third-party liability remains the mandatory base cover under Section I.
- Legal liability to eligible occupants or a pillion rider is a separate optional Section II cover.
- Personal-accident cover for the owner-insured is mandatory in the new structure; cover for other occupants, a pillion rider or another driver is optional.
- Own-damage protection is a separate optional Section IV cover. Third-party insurance does not pay to repair your own car or bike.
- From 15 December 2026, look for the completed option form, a Customer Information Sheet and a policy schedule showing the premium for each selected section.
1. Why the four-layer format matters
Motor insurance has often been sold through short labels such as third-party, package or comprehensive. Those labels are useful starting points, but they do not answer every practical question: are passengers covered, is the owner’s accident protection shown separately, and will damage to the insured vehicle be paid after a crash, fire or theft?
The Supreme Court’s 4 August 2026 judgment in National Insurance Company Ltd. v. Thungala Dhana Laxmi recorded the need for a uniform structure and a customer-friendly information sheet. IRDAI’s reported 2 November 2026 circular turns that broad direction into a point-of-sale format scheduled for policies issued from 15 December 2026. The purpose is visibility: an owner should be able to identify the protection selected instead of inferring it from a bundled headline.
This matters most when a policy is renewed after a change in vehicle use, family travel, regular pillion riding, a new driver, or a change in the vehicle’s value. A lower total on a quote can simply mean that one optional section was not selected. It is not, by itself, evidence that two policies offer the same protection.
2. The four motor-insurance layers in plain language
The table below follows the section structure described in the Supreme Court judgment and the IRDAI format reported on 3–4 November 2026. “Mandatory” describes the stated base requirement; the exact limits, exclusions, deductibles and conditions still come from the issued policy wording.
| Layer | Section | Status from 15 Dec 2026 | What it is for |
|---|---|---|---|
| Third-party liability | I | Mandatory base | Liability for injury, death or property damage caused to a third party. It does not repair the insured vehicle. |
| Occupant or pillion legal liability | II | Optional | Legal liability towards eligible occupants, a pillion rider or covered employees, subject to the policy’s exclusions and registered seating capacity. |
| Personal accident | III(i) and III(ii) | Owner-insured mandatory; others optional | Accident protection for the owner-insured, with separate optional treatment for occupants, a pillion rider or a driver other than the owner. |
| Own damage | IV | Optional | Loss of or damage to the insured car or bike, such as accident, fire or theft where the policy wording covers it. |
Third-party liability is not own-damage cover
Section I protects against a legal liability owed to someone else. It is the minimum motor cover required under Section 146 of the Motor Vehicles Act, as discussed in the judgment. If your own vehicle is damaged, a third-party-only policy is not the section to look for; that question belongs to own-damage cover and its terms.
Occupant liability and personal accident are different
Section II deals with legal liability towards specified occupants or a pillion rider. Section III deals with personal-accident protection for named categories of people. They can relate to the same journey but answer different claim questions, so do not treat “passenger cover” as a single all-purpose promise.
ET’s report on the IRDAI circular says the occupant-liability section excludes the owner-insured and immediate family members, including parents, spouse and children, and is restricted by the vehicle’s registered seating capacity. Read the policy wording and Customer Information Sheet for the precise scope before assuming every person travelling in the vehicle is covered.
3. What changes when you see “comprehensive”
A comprehensive or package policy has traditionally been understood as a combination of third-party and own-damage protection, often with personal-accident and add-on elements. The new structure does not make the word “comprehensive” a substitute for reading the schedule. The useful comparison is section by section: Section I, Section II, Section III and Section IV, followed by exclusions, deductibles, limits and add-ons.
Use the third-party versus comprehensive insurance guide for the basic cover distinction, then check the issued document against the new option form. If an advertisement says “full cover” but the schedule does not identify the occupants or own-damage section, ask for the wording before treating that protection as confirmed.
The new format also separates choice from pricing. The Supreme Court left optional-cover pricing to insurers and market forces, while the IRDAI format requires the selected cover and premium to be visible. That means two owners can receive different totals for legitimate reasons: vehicle, usage, insurer pricing, selected sections, deductibles and add-ons can all differ.
4. How to read the premium and do the rupee math
Do not compare only the final payable number. First compare which sections are selected, then compare the premium attached to each section. The example below is an arithmetic illustration, not a market quote or a recommendation. Replace the inputs with the figures on the actual schedule for the policy issued on or after 15 December 2026.
Illustrative 15 December 2026 quote: Section I shows ₹3,200, Section II shows ₹450, Section III shows ₹750 and Section IV shows ₹12,500. The cover subtotal is:
₹3,200 + ₹450 + ₹750 + ₹12,500 = ₹16,900, before any tax or levy displayed separately by the insurer.
If Section II is not selected, the illustrative cover subtotal becomes ₹16,450. The ₹450 difference is not automatically a saving: it represents a different scope of protection. The correct comparison is “what cover is selected for ₹16,900 versus what cover is selected for ₹16,450?” Actual premiums vary by vehicle, insurer, policy terms, profile and selected protection; the IRDAI circular does not create one universal premium for every car or bike.
Owners who want to place an insurance quote beside their monthly driving budget can use the FuelPrice fuel-cost calculator for the fuel portion. Keep that calculation separate from insurance: fuel use does not determine whether an occupant or own-damage claim is covered.
5. Who needs to pay attention before renewal?
- Private-car owners: check whether the policy issue or renewal date falls on or after 15 December 2026 and look for the four section names rather than relying only on “comprehensive”.
- Two-wheeler owners: check both the owner’s personal-accident section and the treatment of a pillion rider. A pillion rider’s legal-liability and personal-accident protections are not the same thing.
- Families that regularly travel together: read the Section II exclusions and the vehicle’s registered seating capacity. Do not assume that a family member is included just because the vehicle has a seat.
- Owners with an existing third-party policy: ET reports that occupant-liability cover can be added during the policy period for an additional premium through the insurer that issued the third-party policy, without cancelling the existing policy. The endorsement’s effective date and time matter.
- New-vehicle buyers: the Supreme Court judgment separately directed four years of third-party insurance for new cars and six years for new two-wheelers. Treat that as a dated court direction and verify the actual policy documents and implementation instructions attached to the purchase.
- Commercial or business-use vehicle owners: the current four-layer reporting concerns private cars and two-wheelers. Do not transfer the same assumptions to a taxi, goods vehicle or other commercial policy without checking its wording.
6. Policy-checklist before you accept a quote
- Write down the policy issue date, expiry date and vehicle registration details. Confirm whether the new format applies to the document being issued.
- Ask for the customer option form and Customer Information Sheet. Keep the completed form with the policy schedule.
- Check Section I first: the third-party cover should be present and its premium should be identifiable.
- For Section II, identify who counts as an eligible occupant or pillion rider, who is excluded, and whether the registered seating capacity limits the cover.
- For Section III, separate the owner-insured’s personal-accident cover from any optional cover for occupants, a pillion rider or another driver. Read the event definitions, limits and exclusions.
- For Section IV, compare the insured vehicle’s own-damage protection, deductibles, exclusions, claim conditions and selected add-ons. A third-party-only quote cannot be compared with an own-damage-inclusive quote as if they were identical.
- Compare the new schedule with the expiring schedule and record every changed section, limit, deductible and endorsement. The car-insurance renewal checklist after a claim is useful when a past claim or no-claim history affects the comparison.
- Save the policy PDF, option form, CIS, payment receipt and insurer contact details. For a claim dispute or an exclusion question, use the policy’s grievance route and keep the written response.
For a separate explanation of why a claim can fail because of a lapse, licence or exclusion, see the car-insurance claim-rejection guide. The aim is to understand the issued contract, not to assume that a policy label guarantees payment.
7. Frequently asked questions
Does every motor-insurance policy become four separate policies?
No. The change is a four-layer presentation and selection structure within motor insurance. The policy schedule should identify the sections and their premiums, but that does not mean the owner is buying four unrelated contracts.
Is own-damage cover mandatory?
No. Third-party liability is the mandatory base, while own-damage protection is optional in the described structure. A vehicle owner comparing quotes should check whether Section IV is selected before comparing totals.
Can an existing policyholder add passenger or pillion cover mid-term?
ET reports that occupant-liability cover may be added during the policy period for an additional premium through the insurer that issued the third-party policy, without cancelling that policy. The endorsement should state when the added cover begins, so keep that document with the original schedule.
Will the four-layer structure make insurance cheaper?
Not automatically. It makes the selected sections and their premiums easier to see. Optional-cover prices remain dependent on the insurer, vehicle, terms and profile, so the total can rise or fall with the protection selected.
