Aquaplaning Accidents in NSW: What Evidence and Records to Keep for a CTP Claim

Drivers involved in aquaplaning accidents in Greater Sydney should preserve photographs of the scene, weather data, medical records, and insurer correspondence to support a CTP claim. SIRA’s guidelines confirm that evidence of road and weather conditions may help establish the cause of the accident, while medical evidence is critical for injury assessment under the Motor Accident Injuries Act 2017.

Understanding Aquaplaning and CTP Claims in NSW

If you were involved in a motor vehicle accident in Greater Sydney due to aquaplaning, where a vehicle loses traction on wet roads and slides on a layer of water, you may be entitled to compensation under the NSW Compulsory Third Party (CTP) insurance scheme. The Motor Accident Injuries Act 2017 (MAIA) governs all CTP claims in NSW, including those arising from weather-related incidents like aquaplaning. To support a claim, you must gather and preserve specific evidence and records that demonstrate the accident occurred, the nature of your injuries, and the impact on your life. This includes details about the weather, road conditions, vehicle performance, and medical treatment.

Key Evidence to Collect After an Aquaplaning Accident

Immediate actions after an accident can significantly affect your ability to claim compensation. You should:

  • Take photographs of the vehicle’s position, tyre marks, and road surface immediately after the incident.
  • Record the weather conditions, including rainfall intensity and duration, using a weather app or official Bureau of Meteorology data.
  • Note the time, location, and road conditions (e.g., standing water, surface drainage, road gradient) at the time of the accident.
  • Obtain contact details from any witnesses, including other drivers, pedestrians, or emergency personnel.
  • Report the accident to the police if it involved property damage, injury, or a collision with a fixed object.

These details help establish that the accident was caused by wet weather and road conditions, which may be relevant to proving the accident occurred as a result of aquaplaning.

Essential Records for a CTP Claim

To support your claim, you must retain and provide a range of records. These include:

  • Medical records from your first visit to a doctor, hospital, or emergency department after the accident.
  • A record of all subsequent medical treatment, including visits to a general practitioner, specialist, physiotherapist, or psychologist.
  • A copy of any accident report submitted to the police or insurer.
  • Documentation of lost income, including payslips, employer letters, or tax returns if you were unable to work.
  • Records of out-of-pocket expenses related to the accident, such as transport costs, medication, or home modifications.
  • Correspondence with your insurer, including claim forms, letters, and email exchanges.

SIRA, the NSW regulator for motor accident claims, confirms that a claimant must provide evidence that supports the nature and extent of their injuries and how those injuries have affected their daily life and capacity to work.

How SIRA Guides CTP Claims Involving Wet Weather

SIRA’s guidance on motor accident claims states that claims arising from wet weather conditions, including aquaplaning, are assessed under the same legal framework as all other CTP claims. The focus is on whether the injury was caused by the accident, not on the weather itself. However, evidence of weather and road conditions may help establish that the accident occurred as a result of loss of vehicle control due to water on the road.

SIRA notes that claims involving soft tissue injuries, such as whiplash or back strain, are subject to the threshold provisions in the MAIA. This means that if your only injuries are soft tissue injuries, you may not be eligible for damages unless you meet the threshold for a permanent impairment. Evidence of neurological signs, such as numbness, weakness, or altered reflexes, may be critical in establishing that an injury extends beyond simple soft tissue damage.

Time Limits and Procedural Requirements

There is a strict time limit to begin a CTP claim. You must notify your insurer and start the claim process within three years of the accident date. While you are not required to file a claim immediately, delaying may affect your ability to obtain evidence or medical treatment. The sooner you begin, the better your chance of securing accurate records and timely support.

If your claim is denied or you disagree with the insurer’s assessment, you may apply to the NSW Civil and Administrative Tribunal (NCAT) for a review. You must file a review application within 12 months of receiving the insurer’s decision. It is important to keep all correspondence and decisions from the insurer to support any review.

When to Seek Legal Advice

While not required, seeking advice from a legal professional can help you understand your rights and ensure you meet all procedural requirements. A solicitor can assist in gathering evidence, interpreting medical reports, and navigating disputes with insurers. This is particularly important if your injuries are complex, you have a history of similar injuries, or if the insurer disputes liability or the extent of your injuries.

Hypothetical Example

A driver in Sydney’s western suburbs was involved in a single-vehicle accident on a motorway during heavy rain. The vehicle skidded on a stretch of road with poor drainage, resulting in a collision with a barrier. The driver reported neck and back pain immediately after the accident. Medical records confirmed soft tissue injuries, but also noted neurological signs in the right arm. The driver kept photos of the road, a weather report showing 20mm of rain in one hour, and a police report. These records were critical in supporting a claim for treatment and care benefits and later in establishing eligibility for damages under the threshold provisions.
