Four ways fault can play out after a car accident
Fault rarely decides whether you can claim at all. Most injured people get statutory benefits whoever caused the crash. What fault changes is how long those benefits can run and whether a lump sum is possible. These four positions cover most car accidents.
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
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
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.
Harris Park: local roads, hospitals and evidence of fault
The M4, the Great Western Highway, Church Street and James Ruse Drive carry heavy traffic through Parramatta and Cumberland. On routes this busy, a chain collision can leave fault shared across several drivers. Public hospitals serving the area include Westmead 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 Harris Park 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.

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
- Your injury may be more than a threshold injury and fault will decide damages
- A seatbelt or speed argument is being used to cut your claim
- Fault is split between several drivers and no insurer will take the claim
- The other driver changed their story after the crash
You may not need one
- You were a passenger and nobody disputes which driver caused it
- You mainly need a doctor to record your injuries
- Fault isn't argued and your benefits are being paid
Before any fault argument, get the right care. We can connect you with doctors and allied health experienced with CTP claims, who can treat you and complete a clear Certificate of Fitness whatever happens with fault.

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.
- The lane each vehicle was in, and any lane change
- 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

Chain crashes and split blame
In a two-car crash, the injury claim usually goes to the CTP insurer of the car at fault, which is your own vehicle's insurer if you caused it. When fault is shared or unclear, the insurers may not agree at first. That shouldn't hold up your claim. Lodge with the insurer that fits the evidence you have, and let the fault question be worked out as the claim proceeds.
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.

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.
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.

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.

Evidence that settles fault
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.
Your own account matters too, and consistency is what gives it weight. Write down what happened soon after the crash and keep that note. When you later describe the crash to a doctor, the insurer or a lawyer, tell it the same way. Differences between early and later accounts are one of the first things an insurer looks for.
- Dashcam footage, saved as the original file
- The police event number and any police record
- Photos of both vehicles' damage and final positions
- 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.
If the insurer says you contributed
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
If the other driver says you caused the crash, or the insurer won't accept that the other driver did, the evidence decides it. This is the point where an independent lawyer is often worth talking to. They can test the insurer's reasons, gather what's missing and advise whether to ask for a review. Insurers make decisions under the scheme rules, and those decisions can be challenged.

Frequently asked questions
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 automatically, although it can help. A traffic fine or a criminal charge is a separate process from your claim, and the insurer generally looks at all the evidence rather than relying on it alone. A conviction can be strong support for your account. A charge that is dropped, or no charge at all, doesn't mean the other driver wasn't at fault. Keep a copy of any police paperwork you receive.
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.
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.
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.
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.
