For people in Petersham North, we explain how fault is weighed in a NSW claim and help you decide whether the question needs a lawyer. Often it doesn't. When it does, we'll connect you with one.

Four ways fault can play out after a car accident
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
No share of the fault is the strongest position. Benefits come from the at-fault vehicle's insurer, and a lump sum damages claim may follow if your injury isn't a threshold injury. The insurer still needs evidence before it accepts fault.
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
'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
When a crash was nobody's fault, the claim isn't necessarily over. Under the 'blameless accident' rules, an injured person may be able to claim as if someone were at fault. Whether they apply depends on the facts.

Local context for a fault question in Petersham North
Parramatta Road, City West Link and Victoria Road are stop-start for much of the day, and the WestConnex interchanges add complex merges. Rear-end crashes here can still end in an argument about sudden braking. If you were taken to Royal Prince Alfred Hospital, the ambulance and emergency records often note the type of impact, such as being hit from behind or side-on. That early description can support your version of how the crash happened. Around Petersham station, traffic slows for pick-ups, bus stops and people crossing. A low-speed collision in that setting can still raise real questions about who should have given way, so note what each vehicle was doing.

At the scene: what to notice for fault
Once everyone is safe and anyone hurt has help, your memory of the crash is at its sharpest. Note which lane each car was in, what the lights or signs showed, roughly how fast you were going and where the vehicles came to rest. Write down anything the other driver said about how it happened. These details can decide fault later, and they fade within days.
- The lane each vehicle was in, and any lane change
- What the traffic lights or give-way signs showed
- Whether you and your passengers wore seatbelts
- Weather, light and the road surface at the time

Seatbelts, speed and your share of fault
Contributory negligence means you are found to have contributed to the crash or to your own injuries. Common examples are not wearing a seatbelt, speeding, or travelling with a driver you knew had been drinking. It doesn't usually stop a claim. It can reduce weekly payments after 52 weeks and reduce damages, and above 61% you are treated as mostly at fault.
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.

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.
- Dashcam footage, saved as the original file
- Photos of both vehicles' damage and final positions
- Photos of signals, signs and lane markings
- 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
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
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.
Passengers and drivers caught in the middle of a chain crash often feel stuck between insurers. Your claim generally shouldn't stall while the insurers sort out their shares. Keep a note of every call, who you spoke to and what they said. If no insurer will take responsibility, that is a good moment to ask for advice.

Passengers: why the fault question is usually about the drivers
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.

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.

Frequently asked questions
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.
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.
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.
It can reduce your claim, but it usually doesn't end it. Not wearing a seatbelt is a classic example of contributory negligence. Weekly payments after 52 weeks may be reduced for it, and any damages can be reduced too. How much depends on the evidence, including medical opinion on whether a seatbelt would have changed your injuries. Get advice before you accept the percentage the insurer puts forward.
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.
