Correcting the evidence record
What if the police crash report is wrong?
Identify the exact error and put reliable contrary evidence on the record
A police crash report can be important evidence, but it does not finally decide civil fault or the outcome of a NSW CTP claim. Obtain the available police record, identify the precise factual error, contact NSW Police about providing corrected or supplementary information, and give the CTP insurer the competing evidence. If the insurer relies on the error in a written decision, respond through the appropriate review or Personal Injury Commission process.
A useful challenge is specific. Saying that the report is "wrong" is less effective than identifying the page, sentence, diagram, registration, direction of travel, witness or statement that is inaccurate and showing what reliable evidence supports the correction.
The insurer is responsible for assessing liability under the motor accidents scheme. NSW Police explains that insurers investigate civil and property-fault issues and do not rely solely on the police report. Medical causation, treatment and work capacity are also separate from the police description of the collision.

How do I find out what the police record says?
Keep the event number and ask NSW Police what record is available. An application for an incident report may be made using the current police process. The material available to a party can depend on the nature and stage of the investigation.
Compare the report with your own statement, the scene, dashcam, CCTV, photographs, vehicle damage and independent witnesses. A minor spelling error may have no practical effect, while an incorrect vehicle movement, location or driver identification can be central to liability.
Can the police report be corrected?
Contact the officer, station or Police Assistance Line identified for the event and ask how corrected or supplementary information should be provided. Keep the request factual and attach the supporting material. NSW Police decides how its operational record is maintained; a claimant cannot simply rewrite the report.
Even if police do not amend the original record, preserve proof that the error was raised and give the insurer the correction material. An insurer must assess relevant evidence rather than treating one report as conclusive.
What if the insurer has already relied on the error?
Ask for the written decision, reasons and relied-on material. Identify whether the decision concerns fault, mostly-at-fault status, injury causation, treatment, weekly benefits or damages. Different decisions can have different review routes and periods.
A focused internal review request should match each insurer reason to the correcting evidence. If the dispute remains, the Personal Injury Commission may be able to determine the relevant merit, medical or miscellaneous issue. The correct stream depends on the statutory character of the decision, not the label used by the claimant.
Practical next steps
A practical correction sequence
Build a clear evidence trail rather than sending repeated argumentative emails.
Obtain the available report
Use the police event number and current NSW Police process to request the record available to you.
List each material error
Quote the exact passage or mark the diagram, then state the correction in neutral factual language.
Attach objective support
Use original dashcam, CCTV, photographs, maps, vehicle damage and independent witness evidence.
Provide the correction to police and insurer
Keep proof of delivery, any supplementary statement and the insurer's acknowledgement.
Challenge the actual insurer decision
If the error affects an adverse decision, use the stated review rights and address the insurer's reasons point by point.
Evidence
Evidence checklist
Evidence made close to the accident is usually more persuasive than a later general recollection.
- Police event number, report and any supplementary statement or correction request.
- Original dashcam, CCTV and photographs, preserved without editing.
- Scene measurements, road markings, traffic controls and a marked map.
- Independent witness contact details and signed accounts where appropriate.
- Vehicle repair assessments and damage-pattern photographs.
- Ambulance and hospital records containing an early accident history.
- The insurer's decision, reasons and list of material relied upon.
- A concise chronology showing when each item was created or obtained.
Common problems
- Do not alter an original photograph, video or document. Keep a working copy for annotations.
- Do not assume the police conclusion binds the CTP insurer, court or Commission on civil fault.
- Do not ask a witness to adopt your account. Record their independent recollection in their own words.
- Do not combine a liability challenge with unrelated treatment or PAWE arguments unless the decision genuinely contains several issues.
- A correction request does not automatically pause an insurer review or Commission deadline.
Timing
Reporting and review timing
Act early because video and witness evidence can disappear even where the formal claim period has not expired.
- A crash is generally reported to police within 28 days unless police attended.
- A statutory benefits claim is generally lodged within three months, with 28-day lodgement significant for backdating weekly payments.
- A written insurer decision can carry its own internal-review or dispute period. Read the decision and use its date and review notice.
- Request CCTV and other third-party evidence promptly; its retention period may be much shorter than a legal limitation period.
Frequently asked questions
- Does a police report decide who was at fault?
- No. It is evidence, but the CTP insurer and any later decision-maker assess the complete record for the legal issue before them.
- Can I ask police to change the report?
- You can contact NSW Police to provide corrected or supplementary information and supporting evidence. Police decides whether and how its record is updated.
- What if the diagram has the vehicles reversed?
- Identify the exact diagram error and provide objective scene, damage, video and witness material. Give the correction to both police and the CTP insurer.
- Can I still lodge the CTP claim before the report is corrected?
- Yes. Do not miss the claim period while waiting. Lodge the approved form with the information currently available and promptly provide the correction material.
- What if my own first statement was inaccurate?
- Correct it promptly and transparently. Explain what was wrong, why the mistake occurred and what reliable evidence supports the corrected account.
- Can the PIC correct the police report?
- The Commission does not manage police records. It may assess a motor-accident dispute using the relevant evidence, including why a police entry is said to be unreliable.
