NSW CTP unidentified-vehicle claims

What Does “Due Inquiry and Search” Mean in a NSW CTP Claim?

A person injured by an unidentified vehicle may need to prove that reasonable and timely efforts were made to identify it. This guide explains the legal requirement, the evidence to preserve and what happens if the Nominal Defendant disputes the search.

Evidence used to prove due inquiry and search in an unidentified vehicle NSW CTP claim
A useful search file records the scene, vehicle description, police report, CCTV locations and every follow-up in date order.

The result

The search can be sufficient even when the vehicle remains unidentified.

The standard

What was reasonable depends on the accident, available leads and the injured person’s condition.

Separate issues

Acceptance of the search does not automatically prove fault, causation, benefits or damages.

A vehicle strikes a pedestrian and drives away. A motorcyclist is forced off the road by a vehicle that does not stop. A driver sees only part of a registration plate before the other vehicle disappears. In each situation, an injured person may still have a claim through the Nominal Defendant.

Where the vehicle cannot be identified, section 2.30 of the Motor Accident Injuries Act 2017 requires due inquiry and search to establish its identity. This is more than reporting an accident to police. It is a legal condition that can determine whether an unidentified-vehicle claim can proceed.

The meaning of due inquiry and search

In plain Australian English, it means taking the reasonable steps available in the circumstances to try to identify the motor vehicle involved in the accident. There is no universal list. The search is assessed against the actual accident and the actual injured person, not an ideal investigation imagined later with the benefit of hindsight.

Relevant considerations can include:

  • the person’s injuries, shock and mental condition
  • the time and opportunity to observe the vehicle
  • the information available immediately afterwards
  • whether witnesses or cameras were nearby
  • whether the driver stopped or immediately left
  • whether useful leads were followed promptly
  • whether delay has a supported explanation
  • whether a proposed step had any realistic prospect of assisting

The search does not have to succeed. A claimant can satisfy the requirement even though the vehicle remains unidentified. The important question is whether enough was done in the circumstances.

What the current NSW legislation says

Section 2.30 permits an action against the Nominal Defendant where death or injury was caused by the fault of an owner or driver using or operating a motor vehicle on a road in NSW, but the vehicle’s identity cannot be established. Section 2.30(2) says a claim cannot be made under that provision unless due inquiry and search has been made. Under section 2.30(4), the inquiry or search may be proved orally or by affidavit from the person who conducted it.

Section 1.10A applies the Act’s Nominal Defendant liability provisions to statutory benefits in the same way as damages, subject to necessary or prescribed modifications. Due inquiry and search can therefore affect both statutory benefits and a damages claim. It is still only one issue. A claimant may separately need to establish a motor accident, the unidentified vehicle’s involvement and fault, causation of injury, and eligibility for the particular benefits or damages claimed.

The accident-location requirement is considered separately. Read the guide to what counts as a road or road-related area and the guide to proving the exact accident location.

Unidentified and uninsured vehicles are not the same

Section 2.29 concerns a motor vehicle that can be identified but was not insured. Section 2.30 concerns a vehicle whose identity cannot be established. The express due inquiry and search requirement appears in the unidentified-vehicle provision.

Identified but uninsured

The registration or vehicle is known, but CTP insurance is absent. Section 2.29 may be relevant.

Vehicle cannot be identified

The vehicle drove away or available details do not establish its identity. Section 2.30 and due inquiry and search may apply.

If the vehicle is known but the driver’s name is not, that does not necessarily mean the vehicle itself is unidentified. Compare the uninsured-vehicle claim guide before treating the matter as a hit-and-run claim.

When does the issue commonly arise?

  • hit-and-run accidents
  • a driver stops briefly but leaves without details
  • no-contact crashes caused by a vehicle forcing evasive action
  • an incomplete or incorrectly recorded registration
  • a witness sees a vehicle but cannot identify it
  • debris or a load falls from an unidentified vehicle
  • false vehicle or driver details are supplied
  • CCTV is not secured before being overwritten

A physical impact with the unidentified vehicle is not always required. The Act’s definition of motor accident includes action taken to avoid a collision and a dangerous situation caused by the driving of a vehicle. That does not remove the need to prove the vehicle’s involvement and fault. See the hit-and-run claim guide and the guide to lodging a CTP claim without registration details.

How much searching is enough?

The Court of Appeal has described the inquiry as one that should be prompt and thorough so far as the circumstances permit. Reasonably practical inquiries should be made while useful evidence remains available and in places where there is a realistic prospect of obtaining identifying information.

The requirement does not ordinarily mean a claimant must:

  • undertake a dangerous search or personally confront a suspected driver
  • access information that is not legally available to them
  • conduct every theoretically possible inquiry
  • repeat an inquiry that has produced a final negative result
  • perform a ritual step that could not realistically identify the vehicle

Whether a step was reasonable depends on the prospect that it could identify the vehicle. The authorities recognise that a plainly futile or purely ritual inquiry is not necessarily required, but an obvious, available lead should not be ignored without explanation.

What should you do at the accident scene?

Personal safety and emergency assistance come first. Do not chase a fleeing vehicle, enter traffic or confront a driver. If you are physically and mentally able, record what can be safely observed:

  • full or partial registration number
  • make, model, colour and body type
  • unusual markings, branding, damage or modifications
  • driver and passenger descriptions
  • direction of travel and exact time
  • precise accident point and road position
  • witness names and contact details
  • nearby vehicles or premises that may hold footage

A short voice note made immediately afterwards may preserve details that are later affected by medication, treatment, pain or shock.

What should be done after leaving the scene?

1. Report the accident to police

Give police the location, time, direction, registration details, vehicle and driver description, witnesses and camera locations. Keep the event number and all follow-up communications.

2. Preserve original electronic evidence

Save dashcam and vehicle-camera files, photographs, videos, emergency-call records, location history, rideshare or delivery records and contemporaneous messages. Keep original files where possible.

3. Identify nearby CCTV quickly

Consider shops, petrol stations, homes, apartments, councils, car parks, transport operators, schools, construction sites and commercial vehicles. Ask the holder to preserve footage even if it will only be released to police or under a formal process.

4. Follow up witnesses and useful leads

Record what each witness saw and whether they noted a registration, branding, damage, direction or destination. A company logo, distinctive plate combination or turn into a nearby property may justify a focused inquiry.

5. Keep a dated search log

For every step, record the date, person or organisation, contact method, information requested, response, follow-up and supporting document.

Is reporting the accident to police enough?

A prompt police report is important but is not automatically sufficient. Further steps may be reasonable where there is an obvious witness, visible camera, partial registration, identifiable business or available dashcam. Conversely, a police report may be especially significant where there were no cameras, witnesses, identifying details or other realistic avenue of inquiry.

The test is not whether a particular item appears on a checklist. It is whether the overall response was reasonable in the claimant’s circumstances.

Does the claimant have to conduct every search personally?

No. Relevant inquiries may be performed by or on behalf of the injured person. Depending on the circumstances, police, family, friends, a lawyer, an investigator, a witness, the insurer or another person acting in the claimant’s interests may conduct part of the search.

This is particularly important where the claimant is hospitalised, unconscious, seriously injured, a child or otherwise unable to investigate personally. Keep records showing who made each inquiry, when it was made, what was requested and what the inquiry found. The fact that another person performed the work does not make the evidence less important.

What if the claimant was injured, shocked or confused?

The claimant’s physical and mental condition is highly relevant. The question is not what an uninjured observer might have done with hindsight. It is what was reasonable for that injured person at the time, having regard to pain, shock, medication, disorientation, memory and the need to obtain emergency assistance.

Evidence about capacity at the scene can include:

  • ambulance and emergency department records
  • fractures, bleeding, head injury or loss of consciousness
  • pain scores and medication administered
  • disorientation, shock or memory loss
  • witness observations
  • how long the other vehicle remained
  • what the claimant was doing while it remained

What if the driver stopped but the claimant did not obtain the registration?

This is fact-sensitive. The insurer may examine how long the vehicle remained, whether the claimant spoke with the driver, whether the driver appeared willing to exchange details, whether the claimant understood they were injured, whether they were capable of taking a photograph, why details were not obtained and what was done afterwards.

What if the claimant is young or does not initially realise the injury is serious?

Age, injury, the information available at the time and when the seriousness of the injury became apparent can affect what was reasonably required. Delay still needs to be explained, but the assessment must be made in the claimant’s actual circumstances.

Does delay automatically defeat the claim?

No, but unexplained delay can create serious problems. CCTV may be overwritten, witnesses may forget details, contact information may be lost, vehicles may be repaired, social media material may disappear and the accident location may change. Reasonable inquiries should begin promptly while useful evidence remains available.

Delay may be explicable because of matters such as:

  • hospitalisation or head injury
  • impaired memory or severe symptoms
  • the claimant’s age
  • language barriers
  • initial advice that the injury was minor
  • a delayed diagnosis
  • reliance on someone else to investigate
  • not being informed of the requirement

The evidence should explain both when the need to investigate was understood and what was done once the claimant became able to act.

What if the CCTV has already been deleted?

The loss of CCTV does not automatically prevent a finding that due inquiry and search was made. Record when the camera was first identified, when its owner was contacted, whether preservation was requested, what the ordinary retention period was, whether police or the insurer also sought the footage, and why an earlier request was not reasonably possible.

Keep the email, message or file note showing the request and response. A documented negative result is still evidence that the lead was followed. If the footage was unavailable before the claimant could reasonably request it, explain that directly rather than leaving an unexplained gap.

What if a business refuses to release footage?

A business may say it will release footage only to police, an insurer or under a formal process. Ask it to preserve the footage, record the name of the person contacted, confirm the request in writing, provide the police event number where appropriate, notify police and the insurer, and keep the business’s response.

The requirement is to make reasonable efforts. It does not ordinarily require the claimant to obtain material that the holder is not legally willing or able to release directly, but the attempt and the refusal should be documented.

What should be sent to the insurer?

A useful response is a clear chronology supported by documents, not a folder of unexplained attachments.

Accident information

  • date, time and precise location
  • how the accident occurred
  • all known vehicle and driver details
  • direction of travel
  • why full identification was not obtained

The claimant’s condition

  • injuries, pain, shock or confusion at the scene
  • ambulance and hospital treatment
  • medication administered
  • whether the claimant could move or use a telephone
  • why particular steps were not possible

Search chronology

  • police event number and follow-up
  • witness, CCTV and dashcam inquiries
  • business, resident or community inquiries
  • partial registration and vehicle checks
  • the date and result of every step

Supporting documents

  • emails, call notes, screenshots and negative replies
  • witness details and CCTV responses
  • telephone records, photographs and original files
  • medical records explaining inability or delay
  • the dated search log

Identify any inquiry that could not be completed and explain why. If the insurer letter sets a response date or contains a formal decision, do not assume that the date is optional.

What must the insurer do?

Motor Accident Guidelines clauses 4.136–4.141 require the insurer acting for the Nominal Defendant to explain the requirement in writing and promptly advise whether it considers the search satisfied. If it says the requirement is not met, it must identify the deficiency and how the claimant could satisfy it.

The decision must be based on the available information, be consistent with the facts and contain sufficiently detailed reasons. The insurer must act as a model litigant in Nominal Defendant claims. A bare statement that the requirement is not established may not explain the alleged deficiency adequately.

Questions to put back to the insurer

  • Which particular inquiry does the insurer say should have been made?
  • When does it say that inquiry should have occurred?
  • What identifying evidence does it say was reasonably obtainable?
  • How could that step now identify the vehicle?
  • Has it considered the claimant’s injuries, age and condition?
  • What additional material would cause it to reconsider?

The Nominal Defendant’s two-month decision periods

Section 2.31 may cause the Nominal Defendant to lose the right to reject on the due inquiry and search ground if it does not, within two months after the claim is made, reject on that ground or ask the claimant to conduct due inquiry and search.

It may also lose that right if it does not, within two months after being notified of the claimant’s efforts, refuse to accept that those efforts amount to due inquiry and search. Carefully record the dates of the claim, insurer request, claimant’s response and insurer decision.

These provisions concern the insurer’s right to reject on this particular ground. They do not automatically establish fault, injury, causation, statutory benefits or damages.

What happens if the insurer rejects the search?

Schedule 2 clause 3 identifies whether due inquiry and search has been made, and whether the Nominal Defendant lost the right to reject under section 2.31, as miscellaneous claims assessment matters for the Personal Injury Commission.

The filing sequence depends on the decision wording, internal review position, claim stage and applicable time limit. An application should answer the insurer’s stated reasons and include the full chronology, supporting documents, and evidence explaining capacity and delay. Read the PIC guide, the CTP disputes guide and the case note on Raad v Nominal Defendant [2026] NSWPIC 173.

What happens if court proceedings have commenced?

Section 2.31 allows the Nominal Defendant to apply to dismiss proceedings for failure to conduct due inquiry and search. The application generally must be made within two months after service of the statement of claim and cannot be made if the Nominal Defendant has already lost the right to reject on that ground.

If a valid application is made, the court must dismiss the proceedings unless satisfied that due inquiry and search has been made. This is why the issue should be addressed with evidence early, rather than left unresolved until litigation.

Common mistakes in unidentified-vehicle claims

Waiting for the insurer to investigate everything

The claimant should not assume the insurer will preserve every source of footage or witness evidence.

Relying only on a police event number

The number proves a report exists, but not what information was provided or whether other useful inquiries remained.

Failing to obtain written responses

Without emails, names or file notes, it may be difficult to prove what was requested and what the holder said.

Giving a general statement without dates

A dated record identifying each inquiry and response is more useful than saying only that nearby shops were contacted.

Failing to explain the claimant’s condition

Medical and witness evidence may explain why vehicle details were not obtained even where the driver stopped.

Treating negative results as irrelevant

A response that no footage, record or witness was available helps prove that the lead was followed.

Confusing vehicle identity with driver identity

The statutory inquiry is directed to identifying the motor vehicle, not merely obtaining the driver’s name.

A practical due inquiry and search checklist

  1. Report the accident to police and retain the event number.
  2. Write down every remembered vehicle and driver detail.
  3. Save original photographs, videos and dashcam files.
  4. Obtain witness names and contact details.
  5. Ask nearby camera operators to preserve footage.
  6. Give partial registration and distinctive details to police and the insurer.
  7. Follow credible leads about direction, ownership or business markings.
  8. Record every inquiry and response in a dated search log.
  9. Obtain medical evidence if injury, pain or shock affected the search.
  10. Respond to the insurer with a chronology and supporting documents.

The checklist is a starting point. The appropriate investigation depends on the particular accident and the leads actually available.

Frequently asked questions

Is a police report sufficient due inquiry and search?
Not automatically. A prompt police report is important evidence, but the overall question is whether other reasonably available leads also needed to be followed. If there were no witnesses, cameras, registration details or other realistic leads, the police report may carry greater practical weight.
Do I have to identify the driver as well as the vehicle?
Section 2.30 is directed to establishing the identity of the motor vehicle. If the registration and vehicle can be identified, the fact that the driver’s name is not immediately known does not necessarily make it an unidentified-vehicle claim.
Can I make a claim if I only saw part of the registration?
Potentially. Give the partial registration, vehicle description, location, time, direction and any images promptly to police and the insurer. Whether the vehicle can be identified will depend on what those details and further inquiries reveal.
Can I claim if the other vehicle did not hit me?
Potentially. The statutory definition of motor accident includes action taken to avoid a collision and a dangerous situation caused by the driving of a vehicle. You must still prove that the unidentified vehicle was involved, that its owner or driver was at fault, and that the accident caused your injury.
Do I have to knock on every door near the accident?
Not necessarily. The requirement is reasonable inquiry and search in the circumstances, not every imaginable inquiry. Obvious and potentially useful sources should not be ignored without explanation, but a step that is unsafe, unavailable or plainly futile may not be required.
What if I was taken away by ambulance?
Your injuries, pain, shock and inability to investigate at the scene are relevant. Police, family members, witnesses, lawyers or others may conduct inquiries on your behalf. Keep medical and witness evidence explaining what you were able to do at the time.
What if the vehicle was identified but had no insurance?
That may be an uninsured-vehicle claim under section 2.29 rather than an unidentified-vehicle claim under section 2.30. The vehicle identity, registration and insurance evidence should be checked before choosing the Nominal Defendant pathway.
Does a failed search mean I cannot claim?
No. The search does not have to identify the vehicle. The issue is whether reasonable and timely efforts were made in the circumstances. A well-documented search can satisfy the requirement even though every inquiry produces a negative result.
Can the insurer simply say my search was inadequate?
The Motor Accident Guidelines require sufficiently detailed written reasons. The insurer should identify the deficiency and explain how it says the requirement could be satisfied. Ask the insurer to identify the particular missing inquiry and the evidence it says could still identify the vehicle.
Can the Personal Injury Commission decide the issue?
Yes. Schedule 2 clause 3 identifies due inquiry and search, and whether the Nominal Defendant lost the right to reject on that ground, as miscellaneous claims assessment matters. The correct filing sequence depends on the decision, internal review position and claim stage.

The bottom line

Due inquiry and search is not determined by counting emails or businesses contacted. The real question is whether the claimant, or people acting for them, took the reasonable steps available in the circumstances to try to identify the vehicle.

A strong response shows what information was available, what the claimant could physically and mentally do, what inquiries were undertaken, when they occurred, what each inquiry found, why any further step was impossible or unlikely to assist, and why the vehicle still cannot be identified.

Have you received a due inquiry and search letter?

Review the letter before the evidence or deadline is lost

NSW CTP Claim can review the insurer’s letter, the searches already performed, missing CCTV or witness evidence, the claimant’s condition at the scene, the section 2.31 timing issues and the available review or PIC procedure.
