How Vehicle Modifications Affect CTP Compensation in NSW

If you've been injured in a motor vehicle accident and require modifications to your car, such as hand controls, ramps, or adaptive driving aids, you may have questions about how these changes impact your CTP compensation claim. Under New South Wales law, vehicle modifications are treated as part of your injury-related needs, but their inclusion in compensation depends on specific legal criteria. This article explains how SIRA (State Insurance Regulatory Authority) assesses such claims and outlines practical steps for injured people in Western Sydney.

The Legal Framework for CTP Claims Involving Modifications

New South Wales’ Motor Accident Injuries Act 2017 governs CTP claims. Section 4.4 of the Act specifies that compensation includes "treatment and care benefits" and "weekly income payments" for injuries resulting from a motor accident. However, modifications to a vehicle are not automatically included in compensation. Instead, they are evaluated under the SIRA Motor Accident Guidelines, which outline what constitutes a "reasonable and necessary" modification.

SIRA considers whether the modification is directly related to your injury. For example, if you sustained a spinal injury that limits mobility, hand controls may be deemed necessary. However, if the modification is for convenience rather than medical necessity, such as a custom car seat, it may not qualify. The key question is: Does the modification address a functional limitation caused by your injury?

Practical Steps and Evidence for Modifications Claims

To claim compensation for vehicle modifications, you must provide evidence that:

  • The modification was necessary due to an injury from the accident
  • The modification improves your ability to use the vehicle safely
  • The modification was obtained within a reasonable time after the accident

Important evidence includes:

  • Medical reports confirming your injury and mobility limitations
  • A statement from a medical practitioner about the need for the modification
  • Proof of the modification’s cost (e.g., invoices)
  • A description of how the modification helps you use your vehicle

For example, if you broke your leg in a car crash and now need a ramp to enter your vehicle, you must show that the ramp is essential for your recovery. If the injury was minor and the ramp is for comfort, it may not qualify.

Time Limits and Dispute Resolution

CTP claims have strict time limits. You must notify your insurer within 28 days of the accident. If you’re seeking compensation for modifications, you must also submit your claim within this period. Delays can result in the insurer refusing to cover certain costs.

If your claim is disputed, SIRA may request further evidence. For instance, if the insurer questions whether a modification is "reasonable, " they may ask for a second medical opinion. You can also request a review of the decision by SIRA’s internal appeals process.

When to Seek Legal Advice

Vehicle modifications can be complex. SIRA’s guidelines are technical, and proving the necessity of a modification often requires detailed medical evidence. If you’re unsure whether your modification qualifies for compensation, or if your insurer is disputing your claim, it’s important to seek legal advice. A solicitor can help you:

  • Gather and organise medical and financial evidence
  • Challenge an insurer’s refusal to cover a modification
  • Navigate SIRA’s claims process

Vehicle modifications are not automatically included in CTP compensation. They must be directly related to your injury and meet SIRA’s criteria for "reasonable and necessary" modifications. If you’re in Western Sydney and have questions about how your specific modification fits within these rules, seek professional advice. Every claim depends on its own facts.
