Understanding CTP coverage for aquaplaning injuries in NSW
If you were injured in a motor vehicle accident caused by aquaplaning in Greater Sydney, your treatment costs may be covered under the NSW Compulsory Third Party (CTP) insurance scheme. This coverage applies regardless of who was at fault, as long as the accident occurred in a motor vehicle and resulted in injury. The Motor Accident Injuries Act 2017 (MAIA) governs all CTP claims in NSW, including those involving wet weather conditions such as aquaplaning. Under this law, treatment and care benefits are available to cover reasonable and necessary medical and allied health treatment related to injuries sustained in the accident.
What treatment costs are covered under CTP
CTP insurance in NSW covers a range of treatment costs following an aquaplaning accident. These include medical treatment such as visits to a general practitioner, specialist consultations, physiotherapy, chiropractic care, psychological services, and rehabilitation. The coverage extends to diagnostic services like MRI scans, X-rays, and blood tests that are directly linked to the injury. All treatment must be reasonable and necessary, as determined by a qualified medical practitioner and approved by the CTP insurer. This includes treatment for injuries such as whiplash, back strain, fractures, and soft tissue injuries commonly associated with sudden braking or evasive manoeuvres during aquaplaning.
Evidence required to claim treatment funding
To access treatment funding under CTP, you must provide evidence that the injury occurred in a motor vehicle accident and that the treatment is directly related to that injury. Key evidence includes:
- A medical certificate from a registered medical practitioner confirming the injury and its connection to the accident.
- A detailed treatment plan outlining the type, frequency, and duration of treatment.
- Records of all medical appointments, prescriptions, and diagnostic tests.
- A written account of the accident, including weather conditions, road surface, and vehicle speed at the time.
- Photographs of the vehicle damage, road conditions, and any visible hazards such as standing water or poor drainage.
- Witness statements, if available, describing the accident and the driver’s actions.
SIRA, the NSW State Insurance Regulatory Authority, confirms that CTP insurers must assess claims based on medical evidence and reasonable treatment needs. Claims for treatment costs are not automatically approved and may be subject to review if the insurer questions the necessity or proportionality of the treatment.
How SIRA handles aquaplaning claims in Greater Sydney
SIRA’s approach to motor accident claims, including those involving wet weather and aquaplaning, is consistent across NSW, including Greater Sydney. The authority emphasises that CTP insurers must act in good faith and provide timely assessments. For aquaplaning incidents, the insurer must consider whether the driver’s actions were reasonable under the circumstances, such as whether they were driving at a safe speed for the weather, using appropriate braking techniques, and maintaining a safe distance from other vehicles.
SIRA does not treat aquaplaning claims differently from other motor accident claims in terms of eligibility for treatment benefits. However, the insurer may investigate whether the driver was negligent in failing to adjust to wet road conditions, particularly if the accident occurred on a known high-risk stretch of road such as a motorway or steep gradient. This does not affect entitlement to treatment and care benefits, which are available regardless of fault.
Time limits and procedural steps
There is no strict time limit to notify your CTP insurer about an accident, but it is important to report the injury and begin treatment as soon as possible. Delays in reporting may affect the insurer’s ability to verify the claim or access evidence such as weather reports or traffic camera footage. The insurer must respond to a claim within 28 days of receiving a completed claim form and supporting evidence.
If treatment is denied or delayed, you may request a review from the insurer. If the dispute remains unresolved, you can apply to the NSW Civil and Administrative Tribunal (NCAT) for a determination. The process for review or dispute is governed by the Motor Accident Injuries Regulation 2017 and the Motor Accident Injuries Act 2017.
When to seek independent advice
While CTP insurance covers treatment costs for aquaplaning injuries, the process of claiming can be complex, particularly if the insurer disputes the nature or extent of the injury. It is advisable to seek independent legal or claims advice if:
- The insurer refuses to cover a treatment you believe is necessary.
- You are asked to undergo a medical assessment that you believe is not in your best interest.
- There is a dispute over whether the injury was caused by the accident.
- You have ongoing symptoms that are not resolving despite treatment.
An example: A driver in Sydney’s western suburbs was involved in an aquaplaning incident on a wet motorway in June 2026. The vehicle skidded and collided with a barrier, resulting in a diagnosed soft tissue injury to the neck and back. The driver sought physiotherapy and psychological support. The CTP insurer initially delayed approval for treatment, citing a lack of objective evidence. After the driver submitted a medical report and video footage from the vehicle’s dashboard camera, the insurer approved all requested treatment.
