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.

Where fault leaves your claim: four common positions
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
Your claim goes to the CTP insurer of the vehicle that caused the crash. You can receive statutory benefits, and if your injury is more than a threshold injury, a common law damages claim may also be open to you.
Situation 2
You were partly at fault
Partial fault is common and usually a question of degree. A finding of contributory negligence can lower weekly payments beyond 52 weeks and reduce damages, so the percentage the insurer picks is worth checking.
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
Some crashes happen without any driver being at fault, for example after a sudden medical episode or an unforeseeable mechanical failure. NSW has 'blameless accident' rules that may let an injured person claim in some of these cases. They are technical, so get advice.
General information, not legal advice. Fault and contributory negligence are decided on the evidence. Time limits apply.
Local context for a fault question in St Clair
On Castlereagh Road, Erskine Park Road or the Great Western Highway, rear-end crashes in commuter traffic are common. Even when fault seems obvious, the insurer will want evidence before it accepts it. If you were taken to Mount Druitt 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. With St Marys station and Mount Druitt station nearby, buses and other commercial vehicles are a regular part of local traffic. Many carry cameras, so if one was involved in your crash, ask early whether the footage was kept.

Do you need a lawyer for a fault question?
A lawyer isn't a box to tick after every crash. When fault is clear and accepted, many people run their own claim. When it's argued, split or pinned on you, advice is often worth having.
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's insurer says you caused the crash
- 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 were a passenger and nobody disputes which driver caused it
- You mainly need a doctor to record your injuries
- You only need help identifying the at-fault vehicle's insurer
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
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.
- Where each car came to rest, photographed before moving if safe
- Skid marks, debris and the damage to each vehicle
- Whether you and your passengers wore seatbelts
- Weather, light and the road surface at the time

Dashcam, witnesses and the police record
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.
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.
- The police event number and any police record
- Photos of both vehicles' damage and final positions
- Your own written account from the first days
- 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.

Fault, statutory benefits and damages
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.

If you were the passenger
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.
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.

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.

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.
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
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.
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.
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.
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.
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.
