Fault and your claim: four situations
The insurer will form a view about who caused the crash, and that view shapes the rest of your claim. Find the situation closest to yours below, then check the detail with someone who can see your evidence.
Situation 1
You were not at fault
If another driver caused the crash, their vehicle's CTP insurer deals with your claim. Having no share of the blame keeps the most options open, including a later damages claim where the injury goes beyond the threshold.
Situation 2
You were partly at fault
Partial fault is common and usually a question of degree. A finding of contributory negligence can lower weekly payments beyond 52 weeks and reduce damages, so the percentage the insurer picks is worth checking.
Situation 3
You were wholly or mostly at fault
'Mostly at fault' means contributory negligence greater than 61%. Weekly payments and treatment and care are then generally limited to the first 52 weeks, with no common law damages. Children 16 and under keep treatment and care for as long as they need it.
Situation 4
No one was clearly at fault
Unexplained crashes sit in a grey area. The 'blameless accident' provisions may allow a claim where no driver was at fault, but they don't fit every situation. Talk it through with someone who knows them before you rule anything out.
General information, not legal advice. Fault and contributory negligence are decided on the evidence. Time limits apply.
Bonnyrigg Heights: local roads, hospitals and evidence of fault
The Hume Highway, the M5 and the M7 carry commuter and freight traffic through Liverpool and Fairfield. In a crash with several vehicles, each insurer may take a different view of who caused it. Whether the crash was on Elizabeth Drive or a quiet side street, fault is decided on the evidence as a whole. Skid marks, damage patterns and the final positions of the cars can say more than either driver's account. Hospitals serving the area include Fairfield Hospital. Wherever you were first seen, describe the crash accurately and consistently. Insurers compare early medical notes with later accounts when they decide who caused a collision.
With bus stops for Bonnyrigg, Cabramatta and Liverpool nearby, buses and other commercial vehicles are a regular part of local traffic. Many carry cameras, so if one was involved in your crash, ask early whether the footage was kept.

Do you need a lawyer for a fault question?
Whether you need legal help depends less on how the crash happened and more on what the insurer decides about fault. Use these points as a rough guide, and the free claim check if you're still unsure.
Often worth talking to a lawyer
- No driver seems to be at fault and you've been told you can't claim
- The insurer puts your share of fault above 61%
- You've been asked for a detailed statement about how the crash happened
- A fault decision has been made and the review deadline is running
You may not need one
- You mainly need a doctor to record your injuries
- Fault isn't argued and your benefits are being paid
- The other driver admitted fault and the insurer accepted it
If what you need now is treatment, start there. Ask us about doctors and allied health, such as GPs, physiotherapists and psychologists, who understand CTP claims and the Certificate of Fitness.

The first hours after a crash, and the question of fault
The insurer that decides fault will not have been there. It relies on what people recorded at the time. So record what you can: the time, the weather, the road surface, the lane markings and the direction each vehicle was travelling. If a witness stopped, ask whether they'll give their name. A note written that evening is worth more than a memory months later.
- The lane each vehicle was in, and any lane change
- Skid marks, debris and the damage to each vehicle
- Names and phone numbers of anyone who saw it
- Weather, light and the road surface at the time

How fault is shown after a car crash
Fault is decided on evidence, not on who sounds more certain. The usual pieces are the police event number and any police record, photos of where the cars stopped, the damage to each vehicle, dashcam footage and independent witnesses. No single piece is always decisive. Together they usually show what happened, even when the drivers tell different stories.
Some evidence only exists for a short time: skid marks, debris, temporary signs and camera footage. Other evidence can be gathered later, such as the police record and witness statements. If fault is disputed, a lawyer can ask for footage and records to be kept and, where the claim justifies it, obtain an expert opinion on how the crash happened.
- The police event number and any police record
- Your own written account from the first days
- Camera footage from nearby shops or homes
- Any messages the other driver sent after the crash
Save footage early
Many dashcams loop and record over older files. Copy the crash footage to another device straight away, and keep the original file untouched.

Why fault matters more for a lump sum than for benefits
Think of the claim in two parts. Statutory benefits come first and, for most people, don't depend on who caused the crash. Common law damages come later and depend heavily on it: another driver must have been at fault, you must not have been mostly at fault, and the injury must be more than a threshold injury. That is why fault is worth attention early.
Rules change
Your accident date decides which rules apply. Accidents before 1 December 2017 fall under the older 1999 Act, and some limits changed again on 1 April 2023.

Several vehicles, several insurers: working out fault
When three or more vehicles are involved, fault can be divided between several drivers. That affects which insurer deals with you and may affect how any damages are shared between insurers later. It generally doesn't stop you receiving statutory benefits while that is argued. If the insurers are still disputing it weeks after you lodge, advice is worth getting.
If you were hit from behind and pushed into the car in front, you may have been blameless in both impacts. Make that clear in your account: which impact came first, and whether you had stopped before being hit. Insurers sometimes treat a chain crash as one event, and the sequence is what shows your own share was nil.

Passengers and fault
A passenger isn't driving, so a passenger is rarely found at fault for the crash itself. The claim goes to the CTP insurer of whichever vehicle was at fault. If your own driver caused it, that's the Green Slip of the car you were in, even when the driver is a friend or family member. The insurer responds to the claim, not the driver personally.
Children in the car are in a special position. Whoever caused the crash, a child aged 16 or under at the time can keep receiving treatment and care for as long as they need it. Usually a parent or guardian lodges the claim for them. Fault can still matter for other entitlements, so keep the police record with the child's medical records.

Contributory negligence: when you share the blame
Insurers look at more than who hit whom. They may ask whether you wore a seatbelt, how fast you were going and whether you were distracted. The finding is usually a percentage. A small one trims damages and later weekly payments. One greater than 61% has a much bigger effect, because it rules out damages altogether.
Check the percentage
A contributory negligence finding is usually expressed as a percentage. A few points either side of the 'mostly at fault' line can decide whether damages are possible at all, so ask how the figure was worked out.

When fault is disputed
If the other driver says you caused the crash, or the insurer won't accept that the other driver did, the evidence decides it. This is the point where an independent lawyer is often worth talking to. They can test the insurer's reasons, gather what's missing and advise whether to ask for a review. Insurers make decisions under the scheme rules, and those decisions can be challenged.

Frequently asked questions
Possibly. NSW has 'blameless accident' rules for crashes where no driver was at fault, for example because of a sudden medical episode or an unforeseeable mechanical failure. In some of these cases, an injured person may be able to claim as if someone were at fault. The rules are technical and depend on the facts, so get advice before assuming there's no claim. Statutory benefits may be available in the meantime.
'Mostly at fault' means your contributory negligence is found to be greater than 61%. If you were wholly or mostly at fault, weekly payments and treatment and care are generally limited to the first 52 weeks, and you can't claim common law damages. For accidents from 1 April 2023, most people in that position still receive those first 52 weeks of statutory benefits. Because so much turns on the line, a finding close to it is worth having reviewed.
Less than it does for adults. A child who was 16 or under at the time of the accident can receive treatment and care for as long as they need it, regardless of fault. Fault can still matter for other entitlements, such as any damages claim. A parent or guardian usually handles the claim. Keep the police record and the child's medical records together, and note which driver the police report points to.
The insurer decides on the evidence, not on which account sounds more confident. It will look at the police record, the damage to each vehicle, where the cars stopped, any footage and any independent witnesses. While that happens, most people can still receive statutory benefits. If the insurer accepts the other driver's version and you think the evidence points the other way, the decision can generally be reviewed. That is a good time to get advice.
Not by itself. An apology can be mentioned, but insurers decide fault on the evidence as a whole: police records, damage patterns, photos, footage and witnesses. People apologise for many reasons, and drivers sometimes change their account later. Write down exactly what was said and when, then collect the harder evidence. If fault is disputed, those records will count for more than the apology.
Usually less than people fear. Being partly to blame is called contributory negligence. It doesn't stop you claiming statutory benefits. It can reduce weekly payments after 52 weeks, and it reduces any damages by your share. It only removes damages altogether if your share is found to be greater than 61%. Ask how the insurer reached its percentage, and get advice if it seems high.
