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
If you contributed to the crash or your injuries, for example by not wearing a seatbelt, the insurer may argue contributory negligence. Weekly payments after 52 weeks may be reduced, and any damages can be reduced by your share.
Situation 3
You were wholly or mostly at fault
Being at fault doesn't leave you with nothing. Statutory benefits generally continue for the first 52 weeks, but a damages claim is off the table. The same applies once contributory negligence is found to be greater than 61%.
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.

Willmot: local roads, hospitals and evidence of fault
Rooty Hill Road, Wallgrove Road and Old Windsor Road carry commuters alongside logistics traffic from Eastern Creek. If a commercial vehicle was involved, note the company name, because its records may help show what happened. Intersections along Carlisle Avenue and Buckwell Drive can involve turning arrows, give-way signs and changing lights. If fault is argued, a photo of the signals and lane markings taken on the day is hard to dispute. Public hospitals serving the area include Mount Druitt Hospital and Blacktown 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.
Around Mount Druitt 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.

A car accident lawyer for fault: when it helps
Plenty of car accident claims never involve a fault argument. The ones that do often benefit from advice, because fault controls the lump sum. These lists show when a lawyer is commonly worth a call on fault, and when you may manage alone.
Often worth talking to a lawyer
- You've been asked for a detailed statement about how the crash happened
- A seatbelt or speed argument is being used to cut your claim
- Your injury may be more than a threshold injury and fault will decide damages
- Fault is split between several drivers and no insurer will take the claim
You may not need one
- You only need help identifying the at-fault vehicle's insurer
- You mainly need a doctor to record your injuries
- It was a clear rear-end collision and liability is accepted
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.

At the scene: what to notice for fault
Fault arguments are built from small details. Before the cars are moved, if it is safe, photograph where each one stopped and the damage to each. Look for skid marks, debris and the traffic signals. Then write a short account in your own words: where you were going, what you saw, and when you first noticed the other vehicle. Keep it factual and keep it.
- The lane each vehicle was in, and any lane change
- What the traffic lights or give-way signs showed
- Names and phone numbers of anyone who saw it
- Weather, light and the road surface at the time

Fault, statutory benefits and damages
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.

Whose insurer, when fault is shared or unclear
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
Being a passenger doesn't make fault irrelevant. It shifts the question to the drivers. If the driver of your car and another driver both contributed, your claim may involve both vehicles' insurers. Your own conduct can still come up in limited ways, such as not wearing a seatbelt or travelling with a driver you knew was affected by alcohol.
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.

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.
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.
- Photos of both vehicles' damage and final positions
- Camera footage from nearby shops or homes
- 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.
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
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
A fault finding isn't final just because the insurer has made it. Most insurer decisions can go to internal review, generally within 28 days of receiving the decision, and then to the Personal Injury Commission. Before you accept a finding that you were mostly at fault, have someone look at whether the evidence supports it, because so much turns on that line.

Frequently asked questions
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.
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.
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.
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.
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.
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.
