Vehicle Modifications in CTP Claims: Key Questions for Injured People in Greater Sydney

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 in New South Wales and your vehicle has modifications such as hand controls or mobility aids, you may have questions about how these affect your CTP compensation claim. This article explains the legal framework, practical steps, and key considerations for injured people in Greater Sydney seeking compensation for vehicle modifications.

The NSW CTP Rules Behind Vehicle Modifications

In New South Wales, motor accident claims are governed by the Motor Accident Injuries Act 2017 (MAIA). Under this scheme, injured road users are entitled to compensation for injuries caused by another driver’s fault. However, the presence of vehicle modifications can influence the types of benefits or damages available.

The New South Wales Motor Accident Claims Authority (SIRA) provides guidance on what can be claimed, including the use of mobility aids or vehicle modifications that assist with daily living. These modifications are not considered a separate claim but may affect the calculation of compensation, especially if they were installed as a result of the injury.

Practical Steps and Evidence That Usually Matter

When making a CTP claim involving vehicle modifications, it’s important to gather and preserve evidence that supports your case. This includes:

  • Medical records confirming your injury and the need for modifications
  • Documentation of the vehicle modifications, such as receipts, invoices, or manufacturer details
  • Statements from medical practitioners or mobility specialists explaining the necessity of the modifications
  • Photos or videos of the modifications, if available
  • Any correspondence with your insurer or SIRA regarding your claim

These records help establish the connection between your injury and the modifications, which is essential for a successful claim.

Time Limits, Disputes and When to Seek Advice

CTP claims in NSW have strict time limits. Generally, you must notify your insurer of the accident within 28 days, and you must make a claim within 6 months of the accident. If your claim involves vehicle modifications, it’s important to act quickly to ensure all evidence is preserved and submitted on time.

If your claim is disputed, you may need to seek legal advice to challenge the insurer’s decision. SIRA provides a dispute resolution process, but it’s often beneficial to consult a solicitor who specialises in CTP claims to understand your options.

A Hypothetical Example

Consider the case of a pedestrian who was injured in a car accident and required the installation of hand controls on their vehicle. The claimant’s injuries were classified as a threshold injury under the Motor Accident Guidelines. The insurer initially refused to cover the cost of the hand controls, arguing that the modifications were not directly related to the accident. After reviewing the medical records and the necessity of the modifications, SIRA approved the claim, recognising that the modifications were essential for the claimant’s recovery and daily living.

When to Seek Legal Advice

If you’re unsure whether your vehicle modifications will be covered under your CTP claim, or if your claim has been disputed, it’s important to seek legal advice. A solicitor can help you understand your rights, ensure all evidence is properly submitted, and challenge any unfair decisions made by your insurer.

Next Steps

CTP claims involving vehicle modifications can be complex, especially when the injury is classified as a threshold injury or when the modifications were made after the accident. The available benefits and the timeline for making a claim depend on the specific circumstances of your case.
