Understanding How Insurers Assess Vehicle Modifications in CTP Claims

Where a person's only injuries resulting from the accident are threshold injuries, weekly benefits and treatment and care generally cease after 52 weeks (ss 3.11 and 3.28).

If you've suffered a disabling injury and need vehicle modifications to drive safely, you may wonder how insurers evaluate claims for these changes. In New South Wales, the Motor Accident Injuries Act 2017 and SIRA guidelines govern how insurers assess claims involving hand controls, ramps, or other adaptations. This article explains the legal principles insurers apply, how to challenge unfair decisions, and what evidence matters.

Key Legal Principles for Vehicle Modifications

Under NSW CTP rules, insurers must consider whether modifications are 'reasonably necessary' to allow you to drive safely. This is determined by assessing:

  • Medical evidence confirming your injury prevents you from driving safely
  • Clinical records showing the modification enables safe operation of the vehicle
  • SIRA's guidelines on 'reasonable necessity' for vehicle adaptations

Insurers cannot refuse claims for modifications simply because they are 'costly' or 'not standard'. The focus is on whether the modification allows you to drive safely, not on the type of equipment used.

What Evidence Matters for Vehicle Modifications?

To support your claim, gather:

  • Medical reports from a specialist confirming your injury prevents safe driving
  • Documentation from a registered medical practitioner about the modification's necessity
  • Receipts or invoices for modifications (if disputing insurer valuations)
  • Evidence of how the modification enables safe driving (e.g., a driver's assessment)

Insurers may challenge claims by arguing the modification is 'not essential' or 'not reasonably necessary'. This requires a detailed medical assessment to counter.

How to Challenge Unfair Decisions on the Central Coast

If an insurer denies or limits your claim for vehicle modifications, you can:

  1. Request a review using the insurer's internal dispute process
  2. Seek independent medical advice to challenge the insurer's assessment
  3. Appeal to SIRA if the insurer refuses to reconsider

SIRA's guidelines state that modifications must be 'reasonably necessary' to allow safe driving. This means the modification must:

  • Be directly related to your injury
  • Enable you to operate the vehicle safely
  • Be a practical solution for your specific condition

Time Limits and Practical Steps

You have 52 weeks from the accident date to claim most benefits under the Motor Accident Injuries Act 2017. However, claims for vehicle modifications may require longer timelines if:

  • The modification is not immediately practical
  • Further medical assessments are needed

It's crucial to notify your insurer promptly and keep detailed records of all communications. If you're unsure whether your modification qualifies, seek advice before submitting a claim.

When to Seek Legal Advice

Insurers may apply strict interpretations of 'reasonably necessary' to deny claims. If you believe your modification meets the legal criteria but the insurer refuses to pay, consider consulting a solicitor. Legal advice can help you:

  • Challenge the insurer's interpretation of SIRA guidelines
  • Navigate the formal dispute process
  • Ensure your claim reflects your medical needs
