When that is obvious, many people never need a lawyer. When the drivers disagree or the insurer says you contributed, advice is often worth having. Our free check helps you tell which situation you're in.

Fault and your claim: four situations
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
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
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
'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.
Where crashes near Hornsby Heights happen, and why it matters for fault
On winding roads such as Galston Road, Bobbin Head Road and the Old Pacific Highway north of Berowra, a crash may have no witnesses. Photos of the road and the car positions help settle fault. Hospitals serving the area include Hornsby Ku-ring-gai 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. Streets near Hornsby 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.

Fault after a crash: when to call a lawyer, and when you may not need one
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
- Your injury may be more than a threshold injury and fault will decide damages
- A fault decision has been made and the review deadline is running
- Fault is split between several drivers and no insurer will take the claim
- A seatbelt or speed argument is being used to cut your claim
You may not need one
- The other driver admitted fault and the insurer accepted it
- Your question is about treatment, not about who caused the crash
- You only need help identifying the at-fault vehicle's insurer
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.

At the scene: what to notice for 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.
- What the traffic lights or give-way signs showed
- Skid marks, debris and the damage to each vehicle
- Names and phone numbers of anyone who saw it
- Whether you and your passengers wore seatbelts

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.

If you were the passenger
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.
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.

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.

How fault is shown after a car crash
An independent witness, someone with no link to either driver, can carry real weight. Get their name and phone number at the scene if you can. If you can't, the police record may have their details. Photos of the final positions of the vehicles also matter, since damage patterns often show the angle and order of impact.
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.
- Dashcam footage, saved as the original file
- The police event number and any police record
- Photos of both vehicles' damage and final positions
- 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.
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
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.

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
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.
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.
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.
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.
Keep the original file safe first. Many dashcams record over older footage, so copy it to another device or cloud storage straight away, without trimming or editing it. Tell the insurer you have footage, and give it to police if they're investigating. If fault is disputed, the footage can be one of the strongest pieces of evidence you have, because it shows the crash rather than anyone's memory of it.
