Vehicle Modifications and Injury Documentation for NSW CTP Claims

Where a person's only injuries resulting from the accident are threshold injuries, weekly benefits and treatment and care generally cease after 52 weeks (ss 3.11 and 3.28).

A threshold injury under the Motor Accident Injuries Act 2017 (NSW) includes a soft tissue injury and a psychological or psychiatric injury that is not a recognised psychiatric illness (adjustment disorder and acute stress disorder are the usual examples; s 1.6 and Motor Accident Guidelines Part 5).

If you've been injured in a motor accident involving vehicle modifications on the Central Coast, documenting your injuries is critical to a successful Compulsory Third Party (CTP) claim. SIRA guidelines require specific evidence to support claims related to hand controls, mobility aids, or other modifications. This checklist explains what documentation matters, how SIRA evaluates vehicle modification-related injuries, and steps to take on the Central Coast.

Key CTP Rules for Vehicle Modifications

Under the Motor Accident Injuries Act 2017, CTP claims cover injuries caused by motor vehicles, including those requiring modifications like hand controls or ramps. SIRA guidelines state that injuries must meet the 'threshold injury' definition, meaning they must result in a significant and lasting impact on daily life. For vehicle modifications, this includes injuries that necessitate permanent changes to a vehicle to maintain mobility.

If your injury required a modification (e.g., a hand control system for a wheelchair user), you must prove the modification was directly caused by the accident. SIRA assesses whether the injury would have been 'reasonably foreseeable' without the accident, which can affect eligibility for benefits.

Essential Documentation for Vehicle Modification Claims

To support your claim, gather these documents:

  • Medical records showing the injury's impact on mobility and the need for vehicle modifications.
  • Vehicle modification records (e.g., invoices, receipts, or quotes for hand controls, ramps, or other aids).
  • Accident reports from the Central Coast CTP insurer, including details of the incident and vehicle condition.
  • Witness statements or photographs of the accident scene and vehicle modifications.
  • Income records if you've lost wages due to the injury or modification costs.
  • SIRA claim forms completed accurately, with specific notes on how the accident necessitated the modification.

Time Limits and Dispute Resolution

CTP claims must be submitted within 52 weeks of the accident for most benefits, though some claims can extend beyond this period. If your injury requires long-term modifications, you may need to apply for 'lifetime care' benefits under the Motor Accident Injuries Act 2017. Disputes over vehicle modification claims are resolved by SIRA's independent review process, which includes written submissions and, if needed, a hearing.

When to Seek Legal Advice

If your injury required vehicle modifications and you're unsure how to document the link to the accident, consult a solicitor. On the Central Coast, local SIRA offices can provide guidance, but legal advice ensures your claim meets all SIRA requirements for vehicle modification-related injuries.
