How SIRA Handles Multi-Vehicle Pile-Up Claims in NSW

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 a multi-vehicle pile-up in New South Wales, the New South Wales government’s State Insurance Regulatory Authority (SIRA) determines your compensation under the Motor Accident Injuries Act 2017. SIRA’s approach focuses on the accident’s circumstances, not just who was at fault. This article explains how SIRA assesses liability, what claims are available, and how your entitlements differ from single-vehicle accidents.

Key Principles of SIRA’s Approach to Multi-Vehicle Claims

SIRA applies the Motor Accident Injuries Act 2017 to multi-vehicle pile-ups by prioritizing the injured person’s circumstances. Under the Act, fault is determined based on the accident’s cause, not the number of vehicles involved. For example, if a chain reaction occurs due to a sudden stop, SIRA evaluates whether each driver’s actions contributed to the crash.

Unlike single-vehicle claims, multi-vehicle pile-ups require SIRA to consider contributory negligence. If your actions (e.g., speeding or not wearing a seatbelt) worsened your injuries, your compensation may be reduced. SIRA also assesses whether your injuries meet the threshold injury definition under the Motor Accident Guidelines, which includes spinal nerve-root injuries with neurological signs.

What Claims Are Available After a Multi-Vehicle Accident?

Victims of multi-vehicle pile-ups may claim:

  • Weekly income benefits for lost wages.
  • Treatment and care benefits for medical expenses.
  • Damages for pain, suffering, and long-term effects (if your injuries exceed threshold injuries).

SIRA also considers lifetime care needs if your injuries require ongoing support. However, if your injuries are limited to threshold injuries, benefits like weekly payments typically stop after 52 weeks, as outlined in the Motor Accident Injuries Act 2017 s 4.4.

Practical Steps to Gather Evidence

To support your claim, collect:

  • Police reports detailing the accident’s cause.
  • Witness statements about vehicle movements.
  • Medical records showing your injuries and treatment.
  • Photographs of the accident scene, vehicle damage, and any visible injuries.
  • Income records to prove lost wages.

SIRA emphasizes that accurate documentation is critical. For example, if you were a pedestrian hit by multiple vehicles, your medical records must clearly link your injuries to the accident.

Time Limits and Dispute Resolution

You have 5 years from the accident date to claim benefits under the Motor Accident Injuries Act 2017. If your claim is denied, you can request a review by SIRA or seek legal advice. SIRA’s review process considers new evidence or errors in the initial assessment.

Example: How SIRA Assesses a Chain Reaction Crash

Imagine a scenario where three cars collide in a car park. The first car brakes suddenly, causing the second to swerve into the third. SIRA would:

  1. Determine the cause of the initial stop (e.g., a hazard or mechanical failure).
  2. Assess whether each driver’s actions (e.g., speeding, distraction) contributed to the crash.
  3. Evaluate your injuries against the Motor Accident Guidelines to decide if you qualify for damages.

When to Seek Legal Advice

If your claim is denied or you’re unsure about your entitlements, consult a solicitor. SIRA’s rules can be complex, especially in multi-vehicle cases where liability is shared. A lawyer can help you understand whether your injuries meet the threshold for damages and whether your contributory fault affects your claim.
