How NSW CTP Insurance Funds Treatment Costs for Aquaplaning Injuries

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 were injured in an aquaplaning accident in New South Wales, the state’s Compulsory Third Party (CTP) insurance scheme may cover your treatment costs. Aquaplaning, where a vehicle loses traction on a wet road surface, is a common cause of motor accidents, and the NSW CTP rules apply to these incidents as they do to all road accidents. This article explains how treatment costs are funded under the Motor Accident Injuries Act 2017 (MAIA), the evidence needed to claim funding, and practical steps to take after an aquaplaning accident.

Legal Framework for Aquaplaning Claims

Under NSW CTP laws, the Motor Accident Injuries Act 2017 governs claims for injuries caused by motor vehicle accidents, including those involving aquaplaning. The key principles are:

  • CTP insurance covers treatment costs for injuries caused by motor accidents, regardless of fault. This includes medical treatment, rehabilitation, and related expenses.
  • SIRA guidelines (State Insurance Regulatory Authority) outline how claims are assessed, including documentation of injuries and treatment needs.
  • Wet weather conditions are considered during accident investigations, but they do not affect the right to claim treatment costs under CTP.

The MAIA does not require proof of fault for treatment funding. Even if the accident was caused by a driver’s error, the CTP insurer must cover eligible treatment costs. However, claims for compensation beyond treatment (such as damages for pain or loss of income) depend on meeting specific legal thresholds.

Evidence Needed for Treatment Funding Claims

To claim funding for treatment costs after an aquaplaning accident, you must provide evidence of:

  • Medical records confirming the injury and treatment plan. This includes doctor notes, imaging reports, and prescriptions.
  • Accident details such as the date, location, and circumstances. Police reports, witness statements, and dashcam footage can help establish the incident.
  • Proof of treatment costs such as invoices from medical practitioners, physiotherapists, or psychologists.
  • Documentation of income loss if treatment affects your ability to work. This includes payslips, employment records, and medical opinions on work capacity.

For example, if you suffered a soft-tissue injury (like a sprained wrist) from aquaplaning, your treating doctor must confirm that the injury is a result of the accident and that treatment is necessary. SIRA guidelines specify that injuries must meet the definition of a 'threshold injury' under the MAIA to qualify for treatment funding.

Time Limits and Dispute Resolution

CTP claims must be made within 52 weeks of the accident date. After this period, weekly benefits for treatment-related income loss are generally not available, though treatment costs themselves may still be recoverable. If your claim is disputed, you can:

  • Request a review from the CTP insurer, providing additional evidence.
  • Seek independent medical assessment if the insurer questions the severity of your injury.
  • Contact SIRA for guidance on dispute resolution processes.

If the insurer refuses to fund your treatment, you may need to consult a legal professional to explore further options. However, note that CTP claims are not the same as common law damages claims, they are governed by statutory rules, not general tort law.

When to Seek Legal Advice

Legal advice is recommended if:

  • Your injury is classified as a 'threshold injury' but the insurer disputes the treatment costs.
  • You have suffered a whole-person impairment (WPI) and are seeking compensation beyond treatment.
  • You are unsure whether your aquaplaning accident falls under the CTP scheme.

Legal professionals can help you understand whether your claim meets the criteria for treatment funding, and whether you are eligible for additional benefits such as weekly income payments or lump sum compensation.

Next Steps for Claimants

After an aquaplaning accident, take the following steps:

  1. Seek immediate medical attention to document your injuries.
  2. Report the accident to the police and obtain a report.
  3. Notify your CTP insurer as soon as possible.
  4. Keep detailed records of all treatment costs and income loss.
  5. Review your claim with SIRA or a legal professional if you face delays or disputes.

CTP claims can be complex, especially when wet weather conditions or vehicle dynamics are involved. Understanding the legal framework and gathering the right evidence are essential to securing funding for treatment.
