Internal Injuries - Dangers of Car Accidents

Updated 6 October 2026.

Not every injury from a car accident is visible. A person may have damage beneath the skin or a head injury without an obvious external wound. Looking well immediately after a crash does not rule out a serious problem.

If someone is seriously injured, collapses, has difficulty breathing or appears to be deteriorating, call Triple Zero (000) and ask for an ambulance.

Why internal injuries need attention

Bleeding can occur inside the body following trauma. It may not be possible to judge its severity from visible bruising or the damage to the car. Suspected serious internal bleeding needs urgent medical assessment.

Warning signs can include severe or increasing pain, abdominal swelling, faintness, pale or clammy skin, and blood in vomit, urine or stools. These signs can have different causes; they are reasons to seek care, not a checklist for diagnosing yourself. The Victorian Government's Better Health Channel explains internal bleeding and emergency care.

Watch for head-injury warning signs

Some head-injury symptoms develop later. Loss of consciousness, a seizure, repeated vomiting, increasing confusion or unusual difficulty staying awake after an injury require urgent medical attention. Call 000 for a medical emergency.

Follow any monitoring and discharge instructions provided by a clinician, and seek help again if symptoms develop or worsen after you return home. See healthdirect's head-injury guidance.

What to do after the crash

  • Keep yourself and others away from immediate hazards, and follow emergency-service instructions.
  • Tell the clinician how the collision happened, what symptoms you have and whether they are changing.
  • Mention relevant conditions and medicines, especially medicines that affect blood clotting.
  • Do not drive yourself if you are faint, confused, drowsy or otherwise unwell.

If the situation is not an emergency but you are unsure what care is needed, contact a health professional or call healthdirect on 1800 022 222. Do not delay emergency help to arrange towing, insurance or a replacement car.

Deal with transport once health needs are addressed

Keep your medical instructions and accident records together. If your vehicle is unavailable after a not-at-fault accident, Carbiz can discuss replacement vehicle options once you are safe. Carbiz does not assess injuries or replace advice from a treating health professional.

What To Do If Someone Hits Your Parked Car

Coming back to find your parked car damaged is never fun, but knowing how to respond correctly can save you time, money and stress.

Firstly, understand that getting upset is natural, but taking a deep breath will help you make better decisions. Examine your car thoroughly and document any visible damage, taking multiple photos from different angles, including close-ups of dents, scratches or broken parts, and capturing the surrounding area, such as road signs and markings, for context.

Next, see if you can locate the driver responsible. Sometimes, people leave a note with their contact information and insurance details. If there’s no note, look for witnesses nearby who may have seen what happened. You can also check for CCTV from nearby businesses, homes or on the street, as some areas have coverage. If you’re unsure, consider contacting the local council to find out whether cameras are in place that might have captured the accident.

If the driver didn’t leave a note, or if they did but are unresponsive or the information they provided seems incorrect, contact the police to report the accident and provide all the information you have, including photos, footage and witness statements. Be sure to request a copy of the police report, as it can be useful when dealing with insurance.

If you’re still having a hard time getting a hold of the at-fault driver and therefore cannot claim directly through their car insurer, it’s time to lodge a claim with your own insurance provider, if you have one. Provide them with as much information as possible, including the police report. From there, your insurer can determine whether your coverage, along with the information you have, will cover the damage to your car.

If your car insurer happens to find information about the at-fault driver and is able to have them lodge a claim so the costs of the damage are recoverable, you can contact Carbiz for a replacement car while your car is being repaired or until it’s been deemed a total loss. This ensures you’re not left without a car during this time, giving you peace of mind and the ability to keep your life moving.

What It Means When Your Car Is Declared A Write-Off After An Accident

Updated 6 October 2026.

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.

Contact Carbiz to discuss your accident replacement vehicle options. For a practical checklist, read what to do after receiving a write-off decision.
