Fault and your claim: four situations
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
Sharing some of the blame generally doesn't stop a claim. It can reduce weekly payments after the first 52 weeks and cut down any damages in proportion. How much is often argued, which is where advice helps.
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
When a crash was nobody's fault, the claim isn't necessarily over. Under the 'blameless accident' rules, an injured person may be able to claim as if someone were at fault. Whether they apply depends on the facts.
General information, not legal advice. Fault and contributory negligence are decided on the evidence. Time limits apply.
Regentville roads and the question of fault
The M4, The Northern Road and Mulgoa Road carry heavy commuter traffic, joined by construction vehicles around the Western Sydney International Airport site at Badgerys Creek. When fault is disputed, speed and lane position usually decide it. Hospitals serving the area include Nepean 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. 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
- The other driver changed their story after the crash
- A fault decision has been made and the review deadline is running
- No driver seems to be at fault and you've been told you can't claim
- Your injury may be more than a threshold injury and fault will decide damages
You may not need one
- Your question is about treatment, not about who caused the crash
- It was a clear rear-end collision and liability is accepted
- You were a passenger and nobody disputes which driver caused it
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.

What to note near Regentville that bears on fault
You don't need to decide who caused the crash at the scene, and it's wiser not to argue about it there. Swap details, stay calm and avoid guessing about speeds or blame. What helps most later is a clear record: photos of the vehicles' positions, the road layout and any witness who saw it happen, with their name and number.
- 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
- Weather, light and the road surface at the time

Passengers: why the fault question is usually about the drivers
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.

Whose insurer, when fault is shared or unclear
Chain collisions are where fault gets complicated. The driver who started it may carry most of the blame, but a driver behind who was following too closely can share it. Each vehicle has its own Green Slip insurer. Your task is to record every vehicle involved and the order of the impacts; the insurers' task is to sort out which of them responds.
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.

If the insurer says you contributed
Insurers look at more than who hit whom. They may ask whether you wore a seatbelt, how fast you were going and whether you were distracted. The finding is usually a percentage. A small one trims damages and later weekly payments. One greater than 61% has a much bigger effect, because it rules out damages altogether.
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.

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.
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
- Independent witnesses' names and numbers
- Photos of signals, signs and lane markings
- 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
Fault works more like a dial than a switch. A small share reduces some later entitlements. A share above 61% limits benefits to the first 52 weeks and rules out damages. No share at all keeps every option open. Knowing where the evidence puts you on that dial helps you decide whether a lawyer's view is worth having before the insurer settles its position.
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
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
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.
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.
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.
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.
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.
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.
