Seatbelt Non-Use in CTP Claims: How Insurers Assess Passenger Claims in NSW

A passenger not wearing a seatbelt in an NSW motor accident may still claim CTP compensation. Insurers may reduce benefits if they believe non-use worsened the injury, but must provide medical evidence to support this. Practical steps include preserving medical records, accident evidence, and challenging decisions through review or SIRA. Time limits apply, and independent advice may be needed.

How Seatbelt Non-Use Affects CTP Claims for Passengers in NSW

Passengers who were not wearing a seatbelt at the time of a motor accident in NSW may still be entitled to compensation under the Compulsory Third Party (CTP) insurance scheme. However, insurers may reduce or deny benefits if they determine that not wearing a seatbelt contributed to the injury. The Motor Accident Injuries Act 2017 (MAIA) and the Motor Accident Injuries Regulation 2017 govern these claims. Insurers assess whether the injury would have been avoided or less severe if the seatbelt had been worn, using medical evidence and accident details. This assessment is not automatic and does not prevent a claim from being made.

Legal Framework for CTP Claims Involving Seatbelt Non-Use

Under the MAIA, a claim for compensation is not barred simply because a passenger was not wearing a seatbelt. The insurer must assess whether the injury was caused or worsened by the failure to wear a seatbelt. This is a factual and medical determination, not a legal bar to compensation. The insurer must consider whether the injury would have occurred in a similar way even if the seatbelt had been worn, and whether the injury was more severe than it would have been otherwise.

The Motor Accident Injuries Regulation 2017 allows for a reduction in benefits if the claimant’s failure to wear a seatbelt contributed to the injury. This reduction is not automatic and must be supported by medical evidence. Insurers cannot deny a claim solely on the basis of non-use; they must demonstrate a causal link between the non-use and the injury severity.

What Insurers Consider When Assessing Fault and Injury

Insurers assess several factors when evaluating a claim involving seatbelt non-use. These include:

  • The nature and severity of the injury, particularly whether it was caused by impact with the vehicle interior, such as the dashboard, window, or seat.
  • Medical evidence showing whether the injury would have been less severe if a seatbelt had been worn.
  • The circumstances of the accident, including speed, type of collision, and whether the vehicle was travelling at a low speed.
  • Whether the passenger was seated in a position where a seatbelt would have provided protection.

Insurers may request a medical report from a treating practitioner or a specialist to assess the causal relationship between seatbelt non-use and injury. A report that confirms the injury was not significantly worsened by non-use may support a full claim.

Practical Steps and Evidence to Support a Claim

To strengthen a claim, a passenger should:

  • Seek medical treatment immediately after the accident and keep all records, including diagnostic imaging and treatment notes.
  • Preserve any photographs of the vehicle interior, seatbelt buckles, or injury sites.
  • Provide details of any witnesses who observed the passenger not wearing a seatbelt.
  • Retain any correspondence with the insurer, including written decisions or explanations.

A passenger should not assume that not wearing a seatbelt automatically reduces their entitlement. The insurer must provide a reasoned explanation for any reduction in benefits. If the insurer claims that not wearing a seatbelt caused or worsened the injury, the claimant may request a review or seek an independent medical assessment.

How to Challenge an Insurer’s Decision

If an insurer reduces or denies benefits based on seatbelt non-use, the claimant may challenge the decision. This can be done by:

  • Requesting a formal review from the insurer, citing the need for medical evidence to support the causal link.
  • Applying to the State Insurance Regulatory Authority (SIRA) for a review of the decision, particularly if the insurer refuses to reconsider.
  • Seeking a second medical opinion to assess whether the injury would have occurred or been less severe with seatbelt use.

SIRA provides guidance on how to make a claim and what to include in a submission. The claimant must provide all relevant evidence, including medical reports, accident scene details, and insurer correspondence.

Hypothetical Example: Passenger Injured in a Rear-End Collision

A passenger in a car in Greater Sydney was not wearing a seatbelt during a low-speed rear-end collision. The passenger sustained a whiplash injury and a minor concussion. The insurer initially reduced the weekly income payment by 20% on the basis that not wearing a seatbelt contributed to the injury. The passenger provided a medical report from their treating doctor stating that the injury pattern was consistent with a low-speed impact and that a seatbelt would not have prevented the whiplash. The insurer later withdrew the reduction after reviewing the medical evidence. This example shows that a claim can proceed even if a seatbelt was not worn, provided medical evidence supports that the injury was not significantly worsened by non-use.

Time Limits and When to Seek Advice

There are time limits for making a CTP claim. A claim must generally be made within three years of the accident date. However, if the injury was not immediately apparent, the time limit may begin from the date the injury was first diagnosed. The claimant should not delay in seeking medical attention or notifying the insurer.

Insurers may not always apply the law correctly. If a claim is denied or reduced without sufficient evidence, or if the insurer refuses to provide a clear explanation, the claimant should seek independent legal advice. The process can be complex, and a failure to act within time limits may affect entitlement.
