How SIRA Handles Aquaplaning Accidents in NSW CTP Claims

Aquaplaning accidents, where a vehicle loses contact with the road surface due to water, are treated under the NSW Compulsory Third Party (CTP) scheme. SIRA (State Insurance Regulatory Authority) applies the same legal principles across NSW, including the Illawarra and South Coast regions. However, local factors like road conditions, vehicle maintenance, and driver responsibility may influence assessments.

Key Legal Principles for Aquaplaning Claims

Under the Motor Accident Injuries Act 2017, fault is determined by whether the driver breached a duty of care. SIRA considers whether the driver:

  • Maintained appropriate speed for wet conditions
  • Ensured tyres were suitable for the road surface
  • Took reasonable steps to avoid the accident

Aquaplaning is not automatically deemed the driver’s fault. SIRA evaluates whether the driver’s actions (or inactions) contributed to the loss of vehicle control. For example, a driver who ignored warning signs of heavy rain may be found at fault.

Evidence That Matters in Aquaplaning Claims

To support a claim, you’ll need:

  • Accident reports detailing weather conditions and road surface
  • Witness statements about vehicle speed and road conditions
  • Medical records confirming injuries and their connection to the accident
  • Vehicle maintenance records (e.g., tyre tread depth)

SIRA also considers whether the accident occurred on a motorway or other high-speed road, as this may affect the assessment of risk.

Time Limits and Dispute Resolution

You have 6 months from the accident date to notify your insurer of a claim under the CTP scheme. If your claim is disputed, SIRA will review it based on the evidence. If the outcome is unsatisfactory, you may seek legal advice to escalate the matter.

Practical Example: How SIRA Might Assess an Aquaplaning Claim

Imagine a driver on the Illawarra Highway who loses control due to aquaplaning. SIRA would consider:

  • Whether the driver was exceeding the speed limit for wet conditions
  • Whether the road had standing water or poor drainage
  • Whether the driver had a history of similar incidents

If the driver’s actions (e.g., not reducing speed) contributed to the accident, SIRA may reduce compensation. However, if the accident was unavoidable despite proper precautions, the claim may proceed.

When to Seek Legal Advice

Consult a solicitor if:

  • Your claim is rejected or disputed
  • You’re unsure about fault or entitlements
  • You need help navigating SIRA’s review process

Legal professionals can help you understand how SIRA applies the law to your specific circumstances, including regional factors.
