How NSW CTP insurers assess multi-vehicle pile-up claims
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).
When multiple vehicles are involved in a single crash, determining liability and compensation can be complex. Under NSW’s Compulsory Third Party (CTP) scheme, insurers must assess claims based on fault, injury severity, and statutory rules. This article explains how SIRA handles these scenarios using real-world examples from across NSW.
Key legal principles for multi-vehicle pile-ups
NSW CTP claims are governed by the Motor Accident Injuries Act 2017 (MAIA) and SIRA guidelines. In multi-vehicle pile-ups, liability is determined by:
- Fault allocation: Each driver’s contribution to the crash is evaluated. For example, if a car swerves into a stationary truck and a pedestrian is hit, all parties may share responsibility.
- Threshold injuries: Injuries meeting the MAIA’s soft-tissue threshold (e.g., whiplash) are eligible for statutory benefits. SIRA uses clinical guidelines to assess whether a spinal nerve-root injury qualifies.
- No-fault coverage: CTP insurers must pay for injuries caused by another driver, regardless of fault. However, claims for 'threshold injuries' are limited to 52 weeks of weekly benefits unless the injury meets the whole-person impairment threshold.
Practical examples from NSW
Example 1: A 2023 pile-up on the M1 near Sydney involved three vehicles. SIRA determined that the lead car’s driver was 60% at fault for failing to brake, while the second car’s driver was 30% at fault for tailgating, and the third car’s driver was 10% at fault for misjudging the gap. All three drivers received claims for soft-tissue injuries, with benefits capped at 52 weeks.
Example 2: In a 2022 incident on the Princes Highway near Wollongong, a cyclist was struck by two cars. SIRA assessed the cyclist’s injuries as meeting the threshold injury definition under the MAIA and approved 52 weeks of weekly benefits. The insurers disputed the cyclist’s claim for 'exceeding the 52-week limit, ' but SIRA upheld the decision after confirming the injuries were not classified as whole-person impairment.
Evidence and steps for claimants
To support a CTP claim after a multi-vehicle pile-up, claimants should:
- Document the accident: Obtain police reports, witness statements, and photographs of the scene.
- Seek medical attention: Ensure injuries are recorded in medical records. SIRA requires clinical evidence to confirm threshold injuries.
- Notify insurers: Contact the at-fault driver’s CTP insurer within 52 weeks of the accident. Delays may reduce benefits.
- Review SIRA guidelines: Visit SIRA’s claims page for detailed rules on multi-vehicle claims.
Time limits and dispute resolution
CTP claims must be submitted within 52 weeks of the accident. If a claimant exceeds this period, they may lose access to statutory benefits, though they can still pursue a common law damages claim if eligible. Disputes over liability or injury severity can be resolved through SIRA’s dispute resolution process or by seeking independent legal advice.
When to seek legal help
Complex multi-vehicle pile-ups may involve overlapping claims, interstate drivers, or disputes over fault. Legal advice is recommended if:
- The claimant is unsure whether their injuries meet the threshold injury definition.
- The accident involved more than three vehicles.
- The claimant has suffered long-term injuries requiring ongoing treatment.
Next steps for claimants
CTP claims after multi-vehicle pile-ups depend on the accident date, injury type, and evidence collected. While SIRA provides a statutory framework, individual circumstances can affect outcomes. To request contact about your circumstances, complete the quick, no obligation enquiry form.
