When an insurer declares a car a write-off, it has assessed the vehicle as a total loss under the policy. The damage may make repairs unsafe, or the cost of repairing the car may make a repair uneconomical. A write-off does not always mean the car is visibly destroyed.
How is a write-off decision made?
The assessment can take account of the vehicle's value, repair costs, salvage value and the policy terms. There is no single repair-cost percentage that determines every write-off across Australia. Ask the insurer for its assessment and the basis for its decision.
A total-loss insurance decision and a vehicle's written-off registration category are related but different matters. Whether a car can return to the road depends on the damage classification and the rules of the relevant state or territory.
Statutory and repairable write-offs
- Statutory write-off: the vehicle meets specified damage criteria and cannot be re-registered for road use.
- Repairable write-off: repairs may be technically possible, but the vehicle has been assessed as uneconomical to repair. This label does not itself authorise repairs or guarantee re-registration.
Requirements vary across Australia. In NSW, an eligible written-off light vehicle needs an Authorisation to Repair from Transport for NSW before work begins. Only limited applications are considered, and vehicles with statutory write-off damage are excluded. Approval, compliant repairs and the required inspections are separate steps.
What happens to your insurance payout?
The settlement depends on your cover and circumstances. It may be based on an agreed value, a market value or a replacement-vehicle benefit if your policy provides one. An excess, outstanding premium or finance arrangements may affect the amount you receive. Ask for a written breakdown before accepting the settlement.
Keep the assessment, photographs, policy documents and correspondence together. If you disagree with the valuation, provide relevant evidence and use the insurer's complaints process. See AAMI's explanation of total-loss claims for an insurer's example; your own policy determines your cover.
Getting around after a not-at-fault accident
If you need a replacement vehicle, tell Carbiz that your car has been declared a write-off. Eligibility, vehicle availability, the hire period and the terms of the agreement need to be confirmed for your circumstances. A write-off does not automatically entitle everyone to unlimited hire.
