Local context for a fault question in St Marys East
On Castlereagh Road, Erskine Park Road or the Great Western Highway, rear-end crashes in commuter traffic are common. Even when fault seems obvious, the insurer will want evidence before it accepts it. Public hospitals serving the area include Mount Druitt Hospital and Nepean Hospital. Ambulance and emergency notes usually record how the crash was described on the day, which can matter if the other driver's account changes later. Streets near St Marys station carry buses, taxis and drop-offs that stop and start without much warning. In a crash with a vehicle pulling out from the kerb, fault often depends on who had to give way.

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.

- Where each car came to rest, photographed before moving if safe
- Skid marks, debris and the damage to each vehicle

What fault changes in your claim
Most people hurt in a car crash can claim statutory benefits regardless of fault, covering weekly payments and reasonable and necessary treatment. Fault matters most for the lump sum. Common law damages are only possible if another driver was at fault, you were not mostly at fault, and your injury is more than a threshold injury. So a fault finding against you can close off damages even while benefits are paid.
Rules change
The fault rules and benefit limits described here apply to accidents from 1 April 2023. Earlier accidents can have different limits, so check the rules for your accident date.

Where fault leaves your claim: four common positions
People often assume that being at fault means getting nothing. That isn't how the NSW scheme generally works. The four situations below show what usually changes as your share of the blame goes up.
Situation 1
You were not at fault
Your claim goes to the CTP insurer of the vehicle that caused the crash. You can receive statutory benefits, and if your injury is more than a threshold injury, a common law damages claim may also be open to you.
Situation 2
You were partly at fault
Sharing some of the blame generally doesn't stop a claim. It can reduce weekly payments after the first 52 weeks and cut down any damages in proportion. How much is often argued, which is where advice helps.
Situation 3
You were wholly or mostly at fault
For accidents from 1 April 2023, a driver found wholly or mostly at fault generally still receives statutory benefits for the first 52 weeks, but cannot claim damages. A child aged 16 or under at the time is still covered for the treatment and care they need, however long that is.
Situation 4
No one was clearly at fault
Some crashes happen without any driver being at fault, for example after a sudden medical episode or an unforeseeable mechanical failure. NSW has 'blameless accident' rules that may let an injured person claim in some of these cases. They are technical, so get advice.
General information, not legal advice. Fault and contributory negligence are decided on the evidence. Time limits apply.

Talk through who caused the crash
Tell us what happened and what the insurer has said about fault. We'll point you to the right help, whether that's a lawyer, a doctor or neither.

Dashcam, witnesses and the police record
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.
The police event number links your claim to the official record of the crash. The insurer can use it to check who was involved and what was reported. It's worth getting even if the crash seemed minor and police didn't attend, because a record made close to the time is harder to dispute than one pieced together later.
- The police event number and any police record
- Independent witnesses' names and numbers
- Photos of signals, signs and lane markings
- Any messages the other driver sent after the crash
Save footage early
Shops, buses and homes with cameras often keep footage only briefly. Ask in writing as soon as you can, giving the date, time and exact spot.
If you were the passenger
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.
Many passengers hesitate to claim because the driver was someone close to them. It helps to know the claim is made against the CTP insurer, which exists for exactly this situation. The driver may be asked for their account, and any fault finding affects their own claim, not your right to make yours. Talk it through if you're worried about how it will land.

Contributory negligence: when you share the blame
A seatbelt argument is the classic example. If the insurer says your injuries were worse because you weren't belted in, it may reduce what you receive. The percentage isn't set by a formula. It's argued on the evidence, including medical opinion about how each injury happened, which makes it worth checking rather than simply accepting.
Check the percentage
If the insurer puts your share of fault above 61%, damages are off the table and benefits are generally limited to 52 weeks. Most insurer decisions can be internally reviewed, generally within 28 days of receiving the decision.

Several vehicles, several insurers: working out fault
Chain collisions are where fault gets complicated. The driver who started it may carry most of the blame, but a driver behind who was following too closely can share it. Each vehicle has its own Green Slip insurer. Your task is to record every vehicle involved and the order of the impacts; the insurers' task is to sort out which of them responds.
The police event number is often the thread that ties a multi-vehicle crash together. It links the drivers, the vehicles and any statements taken at the scene. Keep it with your registration notes. CTP Assist, a free SIRA service on 1300 656 919, can help identify an insurer when you're unsure, though it won't decide fault for you.

Fault disputes: when a lawyer is worth a call
Being told you caused a crash when you believe you didn't is stressful, especially when damages depend on it. Before you respond, gather what you have: the event number, photos, footage, witness details and your own notes. Then get advice. An independent lawyer can say whether the finding looks sound and what challenging it would involve.

Fault after a crash: when to call a lawyer, and when you may not need one
A lawyer isn't a box to tick after every crash. When fault is clear and accepted, many people run their own claim. When it's argued, split or pinned on you, advice is often worth having.
Often worth talking to a lawyer
- The other driver's insurer says you caused the crash
- The insurer puts your share of fault above 61%
- Your injury may be more than a threshold injury and fault will decide damages
- You've been asked for a detailed statement about how the crash happened
You may not need one
- The other driver admitted fault and the insurer accepted it
- You mainly need a doctor to record your injuries
- It was a clear rear-end collision and liability is accepted
Fault may be the legal question, but your injuries are the heart of the claim. We can point you to doctors and allied health who work with CTP claims, including the Certificate of Fitness the insurer needs.

Frequently asked questions
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.
If your claim is against that vehicle's CTP insurer, you'll deal with them to run it, so a call is normal. Stick to facts, don't guess about speeds or injuries you're unsure of, and keep a note of the call. If you're asked for a detailed recorded statement about how the crash happened, you can ask for time to get advice first, especially if they're questioning who caused it.
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.
By looking at the order of events and what each driver did. In a chain crash, the driver who started it often carries most of the blame, but others can share it, for example by following too closely. Each vehicle has its own CTP insurer, and the insurers may split responsibility between them. Your part is to record every registration, the order of impacts and the police event number, and to lodge on time.
Generally, yes. You claim against the CTP insurer of the vehicle at fault, which here is the Green Slip insurer of your friend's car. The claim is against the insurer, not against your friend personally. Passengers are rarely found at fault, though contributory negligence can still be raised in limited cases, for example if you knew the driver had been drinking. Your friend may be asked for their account, which is normal.
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.
