Motor insurance: what's mandatory, what pays, what to do at a crash

Third-party vs comprehensive: the costly confusion

Third-party motor insurance is legally MANDATORY in India under the Motor Vehicles Act — riding/driving without at least third-party cover is an offence, regardless of anything else. It covers damage or injury YOU cause to others — people, vehicles, property.

What it does NOT cover: your own vehicle, your own injuries. A genuinely common and costly mistake is assuming 'I have insurance' means full protection when the policy is only the mandatory third-party portion. Comprehensive = third-party + own-damage cover for your vehicle.

• No policy at all (even TP) = challan + personal liability for third-party damages.
• TP-only is cheapest and legal — but one major accident to your own car comes fully from your pocket.
• Lenders usually insist on comprehensive for financed vehicles — check your loan terms.

IDV, NCB, zero-dep: the three money levers

IDV (Insured Declared Value) is the maximum your insurer pays if the vehicle is stolen or totalled — roughly market value minus age depreciation. Setting IDV too low saves a little premium and costs you lakhs at claim time; setting it absurdly high just inflates premium since payout still follows depreciation.

NCB (No Claim Bonus, up to 50%) is YOUR asset for claim-free years — it follows you, not the car, and transfers to a new vehicle on sale. Small bumper repair vs NCB math: a ₹4,000 claim can cost a ₹8,000+ NCB discount next year — pay small damages yourself.

Zero-depreciation (zero-dep) add-on removes the plastic/fibre depreciation cut on parts — without it, a 3-year-old car's bumper claim pays only a fraction of the part cost. Most valuable for cars under ~5 years old.

• Declare honest IDV near market value — neither rock-bottom nor fantasy.
• Protect NCB: self-pay small repairs below ~your NCB discount value.
• Zero-dep matters most in years 0–5; its value fades as the car ages.

Add-ons in plain words: who actually benefits

Engine protection: pays for engine/gearbox water damage — genuinely useful in flood-prone cities, near-useless elsewhere. Roadside assistance: cheap peace of mind for highway drivers. Return-to-invoice: on total loss/theft, pays the original invoice value instead of depreciated IDV — worth it for new cars (first 2–3 years). Consumables cover: nuts, bolts, oil — small but real payout friction removed.

• Flood city + monsoon parking outdoors = engine protect is rational, not upsell.
• New car + big loan = return-to-invoice closes the loan-vs-IDV gap.
• Skip everything you can't explain back in one sentence — that's the test.

At the accident spot: what to actually do

First: people before paperwork — injuries and safety come before photos and calls. Then: photograph everything (vehicles, number plates, road position, damage close-ups), exchange details, and call your insurer's helpline the same day — most policies require prompt intimation.

FIR needed vs not: theft claims and significant third-party injury/death claims generally need an FIR; minor own-damage bumper claims do not — you file the claim with photos + policy + driving licence + RC. Surveyor inspection happens before repairs — do NOT repair first and claim later, except in genuine roadside emergencies (keep those bills).

• Same-day intimation beats same-week intimation for smooth claims.
• Never admit fault in writing at the spot — state facts only.
• Cashless (network garage) vs reimbursement (any garage, pay-then-claim) works like health insurance — same trade-off.
