Documenting Injuries from Modified Vehicles in NSW CTP Claims

If you've been injured in a motor accident involving a modified vehicle, you'll need to provide detailed documentation to support your CTP claim. The NSW government's State Insurance Regulatory Authority (SIRA) provides specific guidance for modified vehicles, which differs from standard CTP claims. This checklist outlines the key evidence required to establish your injury and vehicle modifications.

What Documentation Matters for Modified Vehicle Claims

  1. Medical Evidence
  • Detailed medical records showing your injury's connection to the accident.
  • Specialist reports confirming the injury's severity, including any spinal nerve-root injuries (per SIRA guidelines).
  • Evidence of long-term consequences, such as chronic pain or mobility issues.
  1. Vehicle Modification Records
  • Proof of modifications (e.g., hand controls, ramps, or adaptive devices).
  • Documentation from a qualified mechanic or vehicle modification specialist.
  • Evidence of the modification's purpose (e.g., aiding mobility after an injury).
  1. Accident and Scene Details
  • Police report or accident report from the scene.
  • Witness statements or contact information.

  1. Financial and Income Records
  • Proof of income loss due to the injury.
  • Records of expenses related to vehicle modifications or medical treatment.
  1. SIRA-Specific Requirements
  • SIRA's
  • Motor Accident Claims* page outlines that modified vehicles may require additional evidence to prove the injury's link to the accident.
  • For threshold injuries (soft tissue injuries), ensure your medical records include spinal nerve-root qualification details (per SIRA's
  • Motor Accident Guidelines*).

Key Differences for Modified Vehicles

Unlike standard CTP claims, modified vehicle cases require evidence showing:

  • How the modification was affected by the accident (e.g., a ramp damaged during the crash).
  • The modification's role in your pre-accident mobility (e.g., a hand control system used before the injury).
  • SIRA's
  • What You Can Claim* page clarifies that modified vehicles may qualify for additional benefits, such as extended treatment and care payments.

Time Limits and Dispute Resolution

CTP claims must be submitted within 52 weeks of the accident, unless an extension is granted. If your claim is disputed, contact SIRA directly or seek legal advice to challenge the decision.

Example Scenario

A cyclist with a modified vehicle (e.g., hand controls) crashes and sustains a spinal injury. To prove the injury's link to the accident, the cyclist must show:

  • Medical records confirming the spinal nerve-root injury.
  • Evidence that the hand controls were damaged during the crash.
  • How the injury affects their ability to use the modified vehicle.

When to Seek Legal Advice

Consult a solicitor if:

  • Your claim is denied without clear reasoning.
  • You need help navigating SIRA's documentation requirements.
  • You're unsure about the 52-week deadline or dispute process.

Every claim depends on its own facts. To request contact about your circumstances, complete the quick, no obligation enquiry form.
