How Seatbelt Non-Use Affects CTP Claims in NSW After the 2017 Reforms

After NSW’s 2017 CTP reforms, a passenger not wearing a seatbelt may still claim compensation if their injury was caused by the accident. The claim may be reduced only if medical evidence shows the injury would have been prevented or less severe with a seatbelt. SIRA oversees assessments based on objective evidence, not automatic exclusion. To request contact about your circumstances, complete the quick, no obligation enquiry form.

What Changed in NSW CTP Claims After the 2017 Reforms?

The 2017 reforms to NSW’s Compulsory Third Party (CTP) insurance scheme, governed by the Motor Accident Injuries Act 2017, introduced a more structured and evidence-based approach to assessing claims involving passengers who were not wearing seatbelts at the time of a motor accident. Prior to these reforms, the impact of seatbelt non-use on a claim was often assessed on a case-by-case basis, with limited consistency across insurers and tribunals. The new framework established clearer principles for determining whether a passenger’s failure to wear a seatbelt contributed to their injuries and whether that should affect compensation entitlements.

Under the current scheme, a passenger’s lack of seatbelt use may reduce or limit entitlements only if it is established that the injury would not have occurred, or would have been less severe, had the seatbelt been worn. This is not an automatic bar to a claim. The focus is on causation and contribution, not on fault alone.

How Seatbelt Non-Use Affects a CTP Claim in NSW

A passenger who was not wearing a seatbelt at the time of a motor accident may still be entitled to CTP benefits, including treatment and care, weekly income payments, and damages, provided the injury was caused by the accident and not significantly worsened by the failure to wear a seatbelt.

The Motor Accident Injuries Act 2017 does not automatically exclude a claim because a passenger was not wearing a seatbelt. Instead, the insurer or the State Insurance Regulatory Authority (SIRA) may assess whether the injury was contributed to by the failure to wear a seatbelt. This assessment is based on medical evidence and accident reconstruction, not on a general rule that non-use automatically disqualifies a claim.

If a passenger’s injuries were caused by the impact of the accident, for example, a head injury from striking the dashboard, and medical evidence shows that wearing a seatbelt would have prevented or reduced the severity of that injury, then the claim may be reduced or denied in part. However, if the injury resulted from the vehicle’s sudden stop or change in direction, and was not directly caused by contact with interior components, the lack of a seatbelt may not be considered a contributing factor.

What Role Does SIRA Play in Assessing Claims Involving Seatbelt Non-Use?

SIRA, the State Insurance Regulatory Authority, is the independent body responsible for administering the CTP scheme in NSW. It provides guidance and oversight on claim assessments, including those involving seatbelt non-use.

SIRA’s Motor Accident Claims Guidelines clarify that insurers must consider whether a passenger’s failure to wear a seatbelt contributed to the injury. This assessment must be based on objective medical evidence, including reports from treating medical practitioners, imaging results, and expert opinions on biomechanics and injury mechanisms.

SIRA does not determine entitlements on a blanket basis. Instead, it ensures that claims are assessed consistently and fairly, with a focus on whether the injury was caused by the accident and whether seatbelt non-use played a role in its severity. If a claim is disputed on this basis, the matter may proceed to review or dispute resolution through SIRA’s formal processes.

Practical Steps and Evidence That Matter

To support a CTP claim where a passenger was not wearing a seatbelt, the following evidence is typically required:

  • A detailed medical record from the treating practitioner, including diagnosis, treatment plan, and assessment of injury causation.
  • A report from a medical expert, if available, explaining whether the injury would have been prevented or lessened by seatbelt use.
  • Photographs of the vehicle’s interior and the passenger’s position at the time of impact, if available.
  • Witness statements describing the passenger’s seatbelt status before and during the accident.
  • A copy of the police report, if one was filed, noting the passenger’s position and any observations on seatbelt use.
  • A record of all treatment received, including rehabilitation and medical appointments.

It is important to preserve all documentation and avoid altering or concealing any evidence. The insurer may request access to medical records, accident scene details, and a statement from the passenger.

Time Limits and Dispute Resolution

A claim for CTP benefits must generally be made within three years of the accident date. This time limit applies regardless of seatbelt use. If a claim is not made within this period, it may be barred unless a court grants an extension.

If an insurer denies a claim or reduces entitlements based on seatbelt non-use, the claimant may request a review. SIRA provides a formal dispute resolution process for contested claims. This includes the opportunity to submit additional evidence and, if necessary, a review by a SIRA-appointed reviewer.

In some cases, a claim may proceed to the Civil and Administrative Tribunal (NCAT) if a resolution cannot be reached. The tribunal will assess the evidence and determine whether the claim should be upheld, reduced, or denied.

Hypothetical Example

A passenger in the front seat of a car was not wearing a seatbelt when the vehicle collided with a tree. The passenger sustained a concussion and soft tissue injuries to the neck and back. Medical evidence showed that the head impact with the dashboard caused the concussion, and a biomechanical expert concluded that wearing a seatbelt would have prevented this injury. In this case, the insurer may reduce or deny the claim for the concussion, as it was directly caused by the failure to wear a seatbelt. However, injuries from the sudden deceleration, such as whiplash, may still be compensable, as they were not prevented by seatbelt use.

Next Steps

Every claim depends on its own facts. The impact of seatbelt non-use on a CTP claim in NSW depends on the nature of the injury, the medical evidence, and whether the failure to wear a seatbelt contributed to its severity. The 2017 reforms did not eliminate entitlements for passengers who were not wearing seatbelts, but they introduced a more rigorous standard for assessing contribution.
