Vehicle Modifications and Daily Activities in NSW CTP Claims

Vehicle modifications after a motor accident can affect NSW CTP claims. SIRA assesses how modifications impact daily activities, income, and rehabilitation. Evidence like medical reports and cost documentation is essential. Seek legal advice if your claim is disputed or if modifications affect your ability to work.

Vehicle modifications can significantly impact your ability to return to daily activities after a motor accident. In New South Wales, the Compensation for Victims of Motor Accidents (CTP) scheme determines entitlements based on how injuries affect your ability to work, live independently, and perform everyday tasks. This article explains how vehicle modifications are assessed under NSW law, what evidence is needed to support claims, and when to seek legal advice.

How SIRA Assesses Daily Activity Limitations

The State Insurance Regulatory Authority (SIRA) evaluates claims under the Motor Accident Injuries Act 2017. When vehicle modifications are involved, SIRA considers:

  • Whether the modification was necessary due to a disabling injury
  • How the modification affects your ability to perform daily activities
  • Whether the modification impacts rehabilitation timelines

For example, if a driver requires hand controls after a spinal injury, SIRA will assess whether this modification limits their ability to work or manage household tasks. Modifications must be medically necessary and directly related to the injury caused by the accident.

Evidence Required for Modifications Claims

To support a claim involving vehicle modifications, you must provide:

  • Medical reports confirming the injury and need for modifications
  • Documentation from a medical practitioner about how the modification affects daily activities
  • Evidence of the modification's cost (e.g., invoices, receipts)
  • Statements from occupational therapists or rehabilitation specialists

SIRA may also request details about your pre-accident mobility and how the modification improves or limits your functionality. Keep records of all medical appointments, therapy sessions, and any correspondence with insurers.

Time Limits and Dispute Resolution

You have 52 weeks from the accident date to claim certain benefits under the CTP scheme. After this period, weekly income payments and treatment benefits are generally limited unless you have a whole person impairment rating of 10% or more. If your claim involves vehicle modifications, it's critical to notify your insurer promptly and provide all required documentation within the statutory timeframe.

Disputes over modifications are resolved through SIRA's assessment process. If your claim is rejected, you may request a review or seek independent medical opinions. It's important to note that SIRA's decisions are not binding unless challenged through formal legal channels.

When to Seek Legal Advice

Vehicle modifications can complicate CTP claims, especially if:

  • The modification affects your ability to work
  • You're unsure if the modification meets SIRA's medical necessity criteria
  • The insurer disputes the link between the modification and your injury

A solicitor specialising in NSW CTP claims can help you navigate SIRA's assessment process, challenge unfair decisions, and ensure you receive appropriate compensation for lost income and rehabilitation costs.

Practical Example

Consider a cyclist in Bathurst who requires a hand control modification after a road accident. SIRA will assess whether the modification allows them to work as a mechanic (their pre-accident job) or if it limits their ability to perform tasks like lifting tools. If the modification prevents them from working, they may be entitled to income support payments.

Next Steps

CTP claims involving vehicle modifications depend on the accident date, injury type, and evidence of how the modification impacts daily life. To request contact about your circumstances, complete the quick, no obligation enquiry form.
