How NSW CTP Insurers Evaluate Fault in Claims

NSW CTP insurers assess liability by examining fault, evidence, and legal criteria outlined in the Motor Accident Injuries Act 2017. Key factors include whether the accident involved a motor vehicle, the nature of injuries, and the role of SIRA guidelines. Insurers prioritize evidence such as police reports, medical records, and witness statements to determine fault.

Key Factors in Liability Assessment

Insurers evaluate claims based on three main factors:

  • Fault determination - Whether the accident involved a motor vehicle and if the driver breached a duty of care.
  • Injury severity - Whether injuries meet the threshold injury definition under the Motor Accident Guidelines, including spinal nerve-root injuries.
  • Evidence quality - Police reports, medical documentation, and witness accounts are critical to proving liability.

Practical Steps for Claimants

To support a claim, injured persons should:

  • Gather police reports and accident details
  • Document medical treatment and recovery progress
  • Preserve witness contact information
  • Maintain records of income loss or care costs

Insurers often request these documents to assess the validity of a claim. For example, a pedestrian hit at a car park must show the accident involved a motor vehicle and that the driver breached a duty of care.

Time Limits and Dispute Options

CTP claimants have 52 weeks from the accident date to claim weekly benefits for threshold injuries. After this period, benefits may be limited unless the injury meets higher impairment thresholds. If an insurer disputes a claim, claimants can:

  • Request a review by the Claims Assessment Service
  • Seek mediation through the NSW Civil and Administrative Tribunal (NCAT)
  • Consult a solicitor for legal representation

When to Seek Legal Advice

Claimants should consider legal assistance if:

  • The insurer disputes liability or benefits
  • The claim involves complex injuries or long-term care needs
  • The accident date predates the current CTP scheme (1 January 2018)
  • There are disputes over medical evidence or fault

Example of Liability Assessment

Consider a cyclist hit at a Western Sydney intersection. Insurers would assess:

  • Whether the driver failed to yield (fault determination)
  • Whether the cyclist sustained a spinal nerve-root injury (threshold injury criteria)
  • Whether the accident involved a motor vehicle (as required by CTP rules)

If the cyclist has a 10% whole person impairment, they may qualify for both weekly benefits and damages. However, if injuries are limited to soft tissue with no neurological signs, benefits may be restricted after 52 weeks.
