Multi-vehicle pile-up claims in NSW: What injured people need to know

If you were injured in a multi-vehicle pile-up in the Blue Mountains or Nepean, you may have questions about who is responsible, what compensation you might receive, and how to claim it. Under NSW’s Compulsory Third Party (CTP) scheme, claims after multi-vehicle accidents depend on fault, injury severity, and the specific circumstances of the crash. This article explains how SIRA handles such claims, what evidence is needed, and how liability is determined.

How SIRA assesses claims after multi-vehicle pile-ups

SIRA (State Insurance Regulatory Authority) administers NSW’s CTP scheme, which covers injuries caused by motor vehicles. In multi-vehicle pile-ups, SIRA determines liability by identifying which driver or drivers were at fault. Fault is assessed based on police reports, witness statements, and evidence of traffic violations. For example, if one driver ran a stop sign and caused the collision, they may be held fully responsible.

If multiple drivers contributed to the crash, SIRA splits liability proportionally. For instance, if two drivers were equally at fault, each would be responsible for 50% of the damages. This affects how much compensation you receive, as CTP claims are based on fault.

What evidence matters for your claim

To support your claim, you’ll need to provide:

  • Medical records showing your injuries and treatment
  • Accident reports from the NSW Police or private investigators
  • Witness statements from people who saw the crash
  • Photographs of the vehicles, road conditions, and injuries
  • Income records if you’re claiming lost wages

SIRA also considers the type of injury. Threshold injuries (e.g., soft tissue damage) are treated differently from more severe injuries. If your injuries meet the spinal nerve-root criteria in the Motor Accident Guidelines, you may qualify for additional benefits.

Time limits and when to seek advice

You have 52 weeks from the date of the accident to claim benefits for threshold injuries. After this period, weekly payments and treatment benefits generally stop unless you have a whole-person impairment rating of 10% or more. If your injuries are more severe, you may still be eligible for long-term compensation.

Disputes over fault or injury severity are common in multi-vehicle cases. If SIRA denies your claim or you’re unsure about your rights, seek legal advice. A solicitor can help you challenge a decision or negotiate a better outcome.

Example: Split liability in a pile-up

Imagine a crash involving three cars: Driver A ran a stop sign, Driver B was speeding, and Driver C was distracted. SIRA would assess fault based on traffic laws. If Driver A was 40% at fault, Driver B 30%, and Driver C 30%, each driver’s insurer would cover their share of the damages. This affects how much compensation you receive from each party.
