A rear-end crash in traffic, a collision at an intersection, a lane change that went wrong: around Box Hill, as anywhere in NSW, the injury claim usually goes to the insurer of the vehicle at fault. 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.

Four ways fault can play out after a car accident
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
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.
General information, not legal advice. Fault and contributory negligence are decided on the evidence. Time limits apply.
Where crashes near Box Hill happen, and why it matters for fault
The M2, the M7, Windsor Road and Old Windsor Road carry much of the Hills traffic. Motorway merges and lane changes at speed can leave two drivers with very different accounts of the same crash. Hospitals serving the area include Blacktown 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 Rouse Hill Metro 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.

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 other driver changed their story after 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 may not need one
- It was a clear rear-end collision and liability is accepted
- The other driver admitted fault and the insurer accepted it
- You were a passenger and nobody disputes which driver caused 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.
- What the traffic lights or give-way signs showed
- Where each car came to rest, photographed before moving if safe
- Names and phone numbers of anyone who saw it
- Exactly what the other driver said, written down that day

If you were the passenger
Passengers usually have the simplest fault position of anyone in a crash. You weren't in control, so the question is only which driver caused it, and that decides which insurer deals with you. Where both drivers share the blame, you may still be blameless yourself. That matters later, because damages depend partly on your own share of fault.
Passengers in a crash between two cars sometimes find that each driver blames the other and neither insurer will accept the claim at first. You don't have to take sides. Give an honest account of what you saw, lodge on time, and let the fault question be worked out between the insurers. If it stalls, that's when advice helps most.

How fault is shown after a car crash
Dashcam footage is often the clearest evidence of fault, but many cameras record over themselves within hours or days. Save the original file as soon as you can, and don't trim or edit it. If another driver or a nearby business may have footage, ask early and in writing, because it may not be kept for long.
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
- Independent witnesses' names and numbers
- Camera footage from nearby shops or homes
- Photos of signals, signs and lane markings
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.

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.

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.
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.

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.
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.
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.
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.
