Common questions after a multi-vehicle pile-up 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).

Injured people involved in multi-vehicle pile-ups in Greater Sydney often ask whether they can claim compensation, who is responsible, and how long they can receive support. These questions arise because multiple vehicles and drivers are involved, which can complicate the process of identifying the insurer and establishing liability. Under NSW law, the Compulsory Third Party (CTP) insurance scheme covers injuries caused by motor vehicle accidents, regardless of fault. This means that even if no single driver is clearly at fault, injured individuals may still be entitled to benefits. The key issue for claimants is not who caused the crash, but whether the injury resulted from a motor vehicle accident and whether it meets the legal thresholds for compensation.

How the NSW CTP system handles multi-vehicle claims

The Motor Accident Injuries Act 2017 (MAIA) governs CTP claims in NSW. When multiple vehicles are involved in a single crash, the CTP insurer of the vehicle that caused the injury is responsible for providing benefits. If it is not possible to determine which vehicle caused the injury, the claim may be referred to a Nominal Defendant. This is a legal entity established by the Motor Accident Injuries Regulation 2017 to handle claims where fault cannot be established. The SIRA (State Insurance Regulatory Authority) oversees the CTP scheme and ensures that claims are processed according to the MAIA and the Motor Accident Injuries Guidelines.

In a multi-vehicle pile-up, the insurer of the vehicle that caused the injury will assess the claim. If the injured person was a driver, passenger, pedestrian, cyclist, or motorcyclist, they may be eligible for benefits. The insurer must determine whether the injury occurred during a motor vehicle accident and whether it qualifies for statutory benefits. This includes treatment and care benefits, weekly income payments, and, in some cases, damages for non-economic loss.

What injured people can claim after a pile-up

Under the CTP scheme, injured people may claim several types of benefits. These include:

  • Treatment and care benefits: to cover reasonable and necessary medical, rehabilitation, and allied health services.
  • Weekly income payments: if the injury prevents the person from working, they may receive payments to replace lost income. These are generally limited to 104 weeks unless a permanent impairment is assessed.
  • Damages for non-economic loss: if the injury is a threshold injury, the person may be eligible to claim damages for pain and suffering, loss of enjoyment of life, and other non-financial impacts. The threshold injury must meet the criteria in the Motor Accident Injuries Guidelines, including a spinal nerve-root injury with neurological signs other than radiculopathy.

If the injury is not a threshold injury, the person may still receive treatment and care benefits and weekly income payments, but will not be able to claim damages. The 52-week rule applies where only threshold injuries are sustained: weekly benefits and treatment and care benefits are generally limited after 52 weeks, unless a permanent impairment is assessed.

Practical steps and evidence that matter

After a multi-vehicle pile-up, the following steps are essential to support a CTP claim:

  • Seek medical attention immediately and keep all records, including diagnosis, treatment plans, and progress notes.
  • Report the accident to the police if it was not already reported. Obtain a copy of the police report, which may include statements from witnesses or details of vehicle damage.
  • Collect contact details from any witnesses, including other drivers and passengers.
  • Take photographs of the scene, vehicle damage, and any visible injuries.
  • Notify the CTP insurer of the vehicle that caused the injury as soon as possible. If the vehicle is unknown, notify the insurer of the vehicle you were in or the one that struck you.
  • Keep all correspondence with insurers, medical practitioners, and employers.

The SIRA provides guidance on what evidence supports a claim. This includes medical reports, income statements, and records of out-of-pocket expenses related to the injury. The insurer may request a medical assessment to determine the nature and extent of the injury.

Time limits and dispute options

There is a 3-year time limit from the date of the accident to commence a claim for damages under the MAIA. This applies to all CTP claims, including those from multi-vehicle pile-ups. For statutory benefits such as treatment and care, there is no time limit to apply, but claims for weekly income payments must be made within 104 weeks of the accident.

If an insurer refuses to pay a claim or disputes the extent of the injury, the claimant may request a review under the SIRA process. If the review is unsuccessful, the claimant may apply to the NSW Civil and Administrative Tribunal (NCAT) for a determination. The SIRA provides a formal dispute resolution pathway for CTP claims.

When to seek legal advice

A multi-vehicle pile-up often involves complex issues of liability, injury causation, and insurer responsibility. While the CTP scheme is designed to provide automatic support, the process can be challenging to navigate, especially when fault is disputed or when a claim for damages is being considered. Injured people may benefit from independent advice to understand their rights, assess the value of a claim, and ensure that all evidence is properly documented and submitted.

A hypothetical example: A pedestrian in Sydney was struck by a car during a pile-up on the M4 motorway. The vehicle that hit them was not identified, and the insurer of the vehicle they were in declined to accept liability. The claim was referred to a Nominal Defendant under the MAIA. The person received treatment and care benefits and weekly income payments for 52 weeks. After a medical assessment, a permanent impairment of 12% was recorded, and they were able to claim damages for non-economic loss.
