Driving in and around Londonderry: fault in local crashes
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. Fault is decided on the evidence as a whole. Skid marks, damage patterns and the final positions of the cars can say more than either driver's account. Public hospitals serving the area include Nepean Hospital and Mount Druitt 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.
With Western Line (St Marys, Werrington, Kingswood, Penrith, Emu Plains), Blue Mountains Line trains through Penrith and Emu Plains, and Buses, with interchanges at Penrith and St Marys 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.

What to note near Londonderry that bears on 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.
- The lane each vehicle was in, and any lane change
- Skid marks, debris and the damage to each vehicle
- Exactly what the other driver said, written down that day
- Whether you and your passengers wore seatbelts

Chain crashes and split blame
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.
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.

Where fault leaves your claim: four common positions
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
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
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.

Seatbelts, speed and your share of fault
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
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.

Evidence that settles fault
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.
The police event number links your claim to the official record of the crash. The insurer can use it to check who was involved and what was reported. It's worth getting even if the crash seemed minor and police didn't attend, because a record made close to the time is harder to dispute than one pieced together later.
- Photos of both vehicles' damage and final positions
- Camera footage from nearby shops or homes
- Photos of signals, signs and lane markings
- Any messages the other driver sent after the crash
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.
What fault changes in your claim
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.

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.

The other driver blames you: what now?
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.

Do you need a lawyer for a fault question?
Plenty of car accident claims never involve a fault argument. The ones that do often benefit from advice, because fault controls the lump sum. These lists show when a lawyer is commonly worth a call on fault, and when you may manage alone.
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
- The other driver's insurer says you caused the crash
- 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
- It was a clear rear-end collision and liability is accepted
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.

Frequently asked questions
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.
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.
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.
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.
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.
