How Vehicle Modifications Affect CTP Compensation in NSW

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 vehicle accident and rely on vehicle modifications like hand controls or mobility aids, you may have questions about how these impact your CTP compensation. Under NSW law, vehicle modifications can influence the types of benefits you're entitled to, but the rules depend on the nature of your injury and the evidence you provide. This article explains how SIRA assesses claims involving modified vehicles, what evidence matters, and how to avoid common mistakes.

Key CTP Rules for Modified Vehicles

The Motor Accident Injuries Act 2017 governs CTP claims in NSW. If your injury meets the 'threshold injury' definition, such as a spinal nerve-root injury with neurological signs, you may be eligible for treatment and care benefits, weekly income payments, or compensation for permanent impairment. However, vehicle modifications are treated as part of your rehabilitation plan, not as a separate claim. SIRA guidelines state that modifications must be clinically justified and directly related to your injury to qualify for benefits.

Evidence to Prove Vehicle Modifications

To support a claim involving vehicle modifications, you'll need:

  • Medical records confirming your injury and its link to the modification
  • Documentation from a specialist (e.g., physiotherapist or occupational therapist) explaining the need for the modification
  • Proof of the modification's cost (e.g., invoices or receipts)
  • Evidence that the modification improves your mobility or safety

For example, if you require hand controls after a spinal injury, your doctor must confirm that this device is medically necessary and not a personal preference. SIRA will assess whether the modification is 'reasonably necessary' under the guidelines.

Common Mistakes with Modified Vehicles

Injured drivers in Ballina often overlook the importance of documenting their vehicle modifications. Failing to provide clear evidence can lead to claims being denied or delayed. For instance, if you install a mobility aid without medical approval, SIRA may reject it as an unnecessary expense. Always ensure your modification is clinically justified and that you have records to support its necessity.

Time Limits and Dispute Options

CTP claims must be made within 52 weeks of the accident if your injuries are classified as 'threshold injuries' under the Motor Accident Injuries Act 2017. If your injury exceeds the threshold (e.g., a 30% whole person impairment), you may have longer to claim. If you disagree with SIRA's assessment of your modification, you can request a review or seek independent medical advice to challenge their decision.

When to Seek Legal Advice

Vehicle modifications can complicate CTP claims, especially if your injury overlaps with workers' compensation or if the accident involved multiple parties. A solicitor can help you navigate SIRA's requirements, ensure all evidence is properly submitted, and challenge decisions that unfairly limit your benefits. Always act promptly, as time limits apply to most claims.
