Where fault leaves your claim: four common positions
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
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
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
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.

Where crashes near Mountain Lagoon happen, and why it matters for fault
Windsor Road, Richmond Road and the Hawkesbury Valley Way link the Hawkesbury with Sydney. On rural stretches of Putty Road or Bells Line of Road, your own photos may be the only record of where the cars ended up. 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. 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.

Fault after a crash: when to call a lawyer, and when you may not need one
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
- No driver seems to be at fault and you've been told you can't claim
- A fault decision has been made and the review deadline is running
- 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
- Your question is about payments, not about who caused the crash
- You only need to know which form to fill in
If the insurer says you were mostly at fault, ask for its reasons in writing and note the date on the letter. An internal review is generally due within 28 days of receiving the decision. At fault vs not at fault

What to note near Mountain Lagoon 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.
- The lane each vehicle was in, and any lane change
- Where each car came to rest, photographed before moving if safe
- Whether you and your passengers wore seatbelts
- Weather, light and the road surface at the time

What fault changes in your claim
Think of the claim in two parts. Statutory benefits come first and, for most people, don't depend on who caused the crash. Common law damages come later and depend heavily on it: another driver must have been at fault, you must not have been mostly at fault, and the injury must be more than a threshold injury. That is why fault is worth attention early.
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
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.
Many passengers hesitate to claim because the driver was someone close to them. It helps to know the claim is made against the CTP insurer, which exists for exactly this situation. The driver may be asked for their account, and any fault finding affects their own claim, not your right to make yours. Talk it through if you're worried about how it will land.

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.
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
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 expert evidence 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.

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.
- Dashcam footage, saved as the original file
- The police event number and any police record
- Photos of both vehicles' damage and final positions
- Your own written account from the first days
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.
Fault disputes: when a lawyer is worth a call
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.

Frequently asked questions
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 expert 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.
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.
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 with the other claim papers, and note which driver the police report points to.
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.
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.
