Aquaplaning Accidents in NSW CTP Claims: How SIRA Handles Wet Weather Incidents

This article explains how SIRA handles CTP claims for aquaplaning accidents in NSW, focusing on evidence like weather conditions and vehicle liability. It outlines practical steps, time limits, and when to seek legal advice for wet weather incidents.

How SIRA Assesses CTP Claims for Aquaplaning Accidents

Aquaplaning accidents, where a vehicle loses contact with the road surface due to water accumulation, are handled under the NSW Compulsory Third Party (CTP) scheme. SIRA (State Insurance Regulatory Authority) administers claims under the Motor Accident Injuries Act 2017. To qualify, the accident must involve a motor vehicle and result in injury or property damage. Wet weather conditions are a key factor in assessing whether the incident falls within the CTP scheme.

SIRA evaluates claims by determining if the accident was caused by a motor vehicle. For aquaplaning incidents, the claimant must prove the accident occurred due to road conditions exacerbated by the other vehicle’s operation. For example, if a driver skidded on a motorway due to spray from another vehicle, the claim would be assessed based on the vehicle’s role in creating hazardous conditions.

Practical Steps and Evidence for Wet Weather Claims

To support a CTP claim after an aquaplaning accident, the claimant must gather specific evidence:

  • Weather records: Proof of heavy rain, standing water, or road conditions (e.g., a weather app screenshot or police report).
  • Accident reports: Details from the scene, including vehicle positions and skid marks.
  • Witness statements: Accounts from others who observed the incident.
  • Medical records: Documentation of injuries, even minor ones, to establish the claim’s validity.
  • Vehicle condition: Evidence that the other vehicle’s operation contributed to the hazard (e.g., speeding or failure to maintain control).

For instance, if a cyclist was injured after a car aquaplaned on a wet road, the claimant would need to show the car’s involvement in creating the hazardous conditions. SIRA may also consider the driver’s responsibility, such as failing to reduce speed in wet conditions.

Time Limits, Disputes and When to Seek Advice

CTP claims must be submitted within a reasonable time, though the exact deadline is not specified in the Motor Accident Injuries Act 2017. Delays could jeopardize the claim, especially if the claimant needs to pursue compensation for injuries. If the claimant’s injuries fall within the 'threshold injury' category (e.g., soft tissue injuries), weekly benefits may be limited after 52 weeks under the Act.

Disputes over liability or compensation are resolved through SIRA’s internal review process. Claimants should seek legal advice if they are unsure about the strength of their evidence, the impact of contributory fault, or whether their injuries meet the threshold for benefits. For example, a claimant who suffered a minor injury but has ongoing medical treatment may need to demonstrate how the injury affects their daily life.

How SIRA Handles Wet Weather Incidents

SIRA’s guidelines emphasize that the CTP scheme covers accidents caused by motor vehicles, regardless of the weather. However, the claimant must prove the vehicle’s involvement. In aquaplaning cases, this often requires showing that the other driver’s actions (e.g., speeding, failure to maintain control) created the hazard. For example, if a car’s wipers were faulty, leading to reduced visibility during rain, the claimant would need to establish the vehicle’s role in the incident.

If the accident occurred on a motorway or other high-speed road, SIRA may consider the risk of aquaplaning as a contributing factor. The claimant should also document any traffic signs or road conditions that could have influenced the incident.

Real-World Example: A Wet Weather Claim

Consider a scenario where a motorist loses control of their car on a wet highway, skidding into a barrier. The accident occurred after heavy rainfall, and the driver’s vehicle aquaplaned due to standing water. In this case, the claimant would need to:

  1. Provide a weather report showing the rain intensity.
  2. Submit a police report detailing the accident.
  3. Show evidence of the vehicle’s condition (e.g., wiper functionality).
  4. Document any injuries, such as whiplash or cuts from the barrier.

SIRA would assess whether the accident was caused by the motor vehicle and whether the claimant’s injuries fall within the CTP scheme. If the claimant’s injuries are below the threshold, they may still receive treatment benefits under the scheme.

Next Steps for Claimants

CTP claims depend on the specific circumstances of the accident, including the date of the incident, the nature of the injuries, and the evidence available. If you’ve been involved in an aquaplaning accident and are unsure about your options, it’s important to act promptly. Time limits and procedural requirements may apply, and the claim could be affected by factors like contributory fault or the type of injuries sustained.

Every claim depends on its own facts. To request contact about your circumstances, complete the quick, no obligation enquiry form.
