Current as at 5 October 2026

Vehicle modifications after a disabling injury can significantly impact caregiver responsibilities and family support. Under NSW Compulsory Third Party (CTP) law, vehicle modifications are assessed as part of compensation claims, but the process involves specific legal considerations. This article explains how vehicle modifications affect caregiver duties, what evidence is required, and how SIRA evaluates these claims. It also outlines time limits and when to seek legal advice for families in Ashfield NSW.

How CTP Rules Apply to Vehicle Modifications

NSW CTP claims under the Motor Accident Injuries Act 2017 cover injuries resulting from motor vehicle accidents. Vehicle modifications, such as hand controls or mobility aids, are considered when assessing the need for ongoing support. SIRA (State Insurance Regulatory Authority) evaluates whether these modifications are medically necessary to enable the injured person to perform daily activities. For example, if a car accident caused a spinal injury requiring a wheelchair, the modification would be reviewed to determine its role in reducing caregiver burden.

Caregiver responsibilities are factored into claims through the 'care and assistance' category. SIRA considers how modifications affect the injured person’s ability to live independently, which in turn influences the level of family support required. However, modifications are not automatically approved; they must meet specific medical criteria outlined in the Motor Accident Guidelines.

Practical Steps and Evidence for Vehicle Modifications

To support a CTP claim involving vehicle modifications, families should gather:

  • Medical reports confirming the need for modifications
  • Documentation from a medical practitioner about how the modification improves mobility or independence
  • Evidence of how the modification reduces caregiver tasks (e.g., reduced need for assistance with transfers)
  • Records of any costs incurred for the modification

For instance, if a cyclist requires a hand control device after a head injury, medical evidence must show that this modification enables them to operate the vehicle safely, thereby reducing the need for constant supervision. Families should also keep records of how the modification impacts daily routines, such as meal preparation or personal hygiene.

Time Limits, Disputes and When to Seek Advice

CTP claims must be submitted within 52 weeks of the accident, though extensions may apply in exceptional circumstances. If a modification is disputed by SIRA, families should seek legal advice promptly. Disputes often arise when modifications are deemed unnecessary or not medically justified. A solicitor can help challenge a decision by presenting expert medical opinions or demonstrating how the modification directly reduces caregiver responsibilities.

Families in Ashfield NSW should also be aware of the 52-week limit for weekly income benefits. If the injured person’s only injuries are threshold injuries (e.g., soft tissue damage), benefits may stop after 52 weeks, even if modifications are still needed. This distinction is critical for long-term planning.

Next Steps for Families

Vehicle modifications in CTP claims require careful documentation to show their impact on caregiver duties. Families should act quickly to submit evidence and seek legal guidance if disputes arise. The process involves balancing medical necessity with legal requirements, making it essential to consult a specialist solicitor for complex cases.
