When a family member is injured in a highway merge accident, caregivers and families may be eligible for support under NSW's Compulsory Third Party (CTP) scheme. This article explains how to claim benefits for care needs, understand eligibility for weekly income payments and treatment benefits, and navigate the claims process. Families should act promptly to submit evidence and seek legal advice if their claim is disputed.

What Families Can Claim Under NSW CTP Laws

Under the Motor Accident Injuries Act 2017, families may claim benefits for care needs arising from a motor vehicle accident. Weekly income payments and treatment benefits are available for injuries meeting the 'threshold injury' definition, which includes soft tissue injuries and certain psychological injuries like adjustment disorder or acute stress disorder (s 1.6). Caregivers may also claim for additional support if the injured person requires ongoing assistance with daily living tasks. However, CTP claims are limited to injuries caused by a motor vehicle accident and not all family-related expenses are automatically covered.

Assessing Care Needs for CTP Claims

To qualify for caregiver-related benefits, families must demonstrate a direct link between the injury and the need for assistance. For example, if a cyclist sustains a soft-tissue injury from a merge collision, their family must show that the injury has caused functional limitations requiring daily support. The Motor Accident Guidelines specify that spinal nerve-root injuries producing neurological signs may still qualify as soft-tissue injuries, even if they do not meet the traditional definition. Families should work with medical professionals to document how the injury impacts the injured person’s ability to live independently, as this directly affects eligibility for caregiver-related benefits.

Evidence and Practical Steps for Caregiver Claims

To support a CTP claim for family care needs, caregivers must gather specific evidence. This includes medical records confirming the injury’s severity, accident reports detailing the merge collision, and witness statements if available. Families should also keep records of additional costs incurred due to the injury, such as transportation to medical appointments or home modifications. SIRA’s 'Making a motor accident claim' guide emphasizes that claims must be submitted within 52 weeks of the accident for certain benefits, although this timeframe may vary depending on the injury’s nature. If the injured person’s only injuries are threshold injuries, weekly benefits and treatment care generally cease after 52 weeks as the Act provides.

Time Limits and When to Seek Advice

CTP claims have strict time limits. Under the Motor Accident Injuries Act 2017, claims for injuries must be made within 52 weeks of the accident, unless the injured person’s condition worsens after that period. Families should note that the 52-week rule applies only to injuries that meet the threshold injury definition. If the injured person’s condition improves or stabilizes within this timeframe, they may no longer be eligible for certain benefits. For caregivers, it is crucial to act promptly to ensure all necessary documentation is submitted before deadlines expire. If an insurer denies a claim or disputes the need for family support, families should consider seeking legal advice. A solicitor can help challenge an insurer’s decision or pursue a claim for additional compensation if the injury meets the criteria for a whole-person impairment rating.

Example: Caregiver Claims in a Merge Collision

Consider a scenario where a family member is injured in a highway merge accident. The injured person requires assistance with daily tasks such as cooking, cleaning, and personal hygiene. Their family must demonstrate that the injury has caused a functional limitation requiring ongoing care. Medical records would show the injury’s impact, while the family’s evidence of time spent caregiving would support the claim. If the injured person’s condition improves after 52 weeks, the family may need to re-evaluate their claim for continued support. This example highlights the importance of accurate documentation and timely action in CTP claims.
