How SIRA assesses fault in roundabout collision claims
In New South Wales, the outcome of a Compulsory Third Party (CTP) claim following a roundabout collision depends on establishing who was at fault, not on proving negligence in a court. The State Insurance Regulatory Authority (SIRA) uses the Motor Accident Injuries Act 2017 to determine liability. Under this law, fault is assessed based on the conduct of the drivers involved, including who had the right of way, whether they followed road rules, and whether they acted reasonably under the circumstances. SIRA does not require a court finding of fault to process a claim. Instead, it relies on evidence such as police reports, witness statements, and vehicle damage patterns to determine responsibility.
Roundabouts are designed to reduce collision severity, but they still involve complex interactions between vehicles. SIRA considers whether a driver failed to yield to traffic already in the roundabout, entered at an unsafe speed, or made an incorrect lane choice. These factors are assessed under the Road Rules 2014, which apply to all motor vehicle movements, including those in roundabouts. The presence of traffic signs, road markings, or camera evidence may also support a determination of fault.
Evidence that supports a CTP claim after a roundabout collision
To establish a valid CTP claim, claimants must provide evidence that supports both the occurrence of the accident and the nature of their injuries. The most critical evidence includes:
- A completed police report, if one was made at the scene
- Photographs of the vehicle damage, road conditions, and any visible road signs or markings near the roundabout
- Witness contact details and statements, if available
- Medical records showing the injury, including diagnosis, treatment, and any ongoing symptoms
- A written statement from the claimant describing how the collision occurred and the immediate aftermath
SIRA requires that medical evidence be provided by a registered medical practitioner. This includes a report confirming the diagnosis, the treatment received, and the impact of the injury on daily activities. For claims involving soft tissue injuries, SIRA applies the Motor Accident Guidelines to assess whether the injury meets the threshold for compensation. These guidelines define specific clinical signs, such as neurological deficits, that must be present to qualify as a threshold injury.
How SIRA’s CTP rules apply to roundabout collisions
SIRA’s approach to CTP claims in roundabout collisions follows the general framework of the Motor Accident Injuries Act 2017. The law provides for three main types of benefits: treatment and care, weekly income payments, and damages. These are not automatic entitlements but depend on the nature of the injury and the claimant’s circumstances.
Treatment and care benefits cover medical treatment, rehabilitation, and support services. These are available regardless of fault, provided the injury resulted from a motor accident. Weekly income payments are available if the injury prevents the claimant from working for more than 13 weeks. The claimant must provide proof of income loss, such as a letter from their employer or pay slips.
Damages for pain and suffering, loss of enjoyment of life, and future care needs are only available if the claimant has a threshold injury. This includes injuries that cause a permanent impairment of at least 10% to the whole person. For soft tissue injuries, SIRA applies a strict definition: a spinal nerve-root injury must produce neurological signs other than radiculopathy to qualify. Radiculopathy alone does not meet the threshold under the Motor Accident Guidelines.
Where a claimant’s only injuries are threshold injuries, the law limits weekly benefits and treatment and care benefits to 52 weeks from the date of the accident. This rule applies regardless of whether the injury is still affecting the claimant. The 52-week limit is not a cap on total compensation but a time limit on certain statutory benefits.
Practical steps after a roundabout collision in Ballina
If you were involved in a roundabout collision in Ballina and believe you have sustained an injury, take the following steps immediately:
- Seek medical attention, even if symptoms appear minor. Delayed symptoms are common after motor accidents.
- Report the incident to the police if it was not already reported. A police report may be essential for a claim.
- Take photographs of the vehicles, road signs, and any visible damage.
- Collect contact details from any witnesses.
- Notify your CTP insurer as soon as possible. SIRA does not require a claim to be made through a solicitor, but early notification helps preserve rights.
If you are uncertain about fault or the value of your claim, contact SIRA directly through its website. SIRA provides information and guidance on making a claim, including how to submit evidence and what to expect during the assessment process.
When to seek independent advice
A roundabout collision may involve complex issues of right of way, driver conduct, and injury causation. SIRA’s assessment is based on available evidence, but it does not guarantee a favourable outcome. If you believe the insurer has misapplied the law, failed to consider evidence, or made a decision that contradicts the Motor Accident Guidelines, you may request a review.
Independent legal advice is recommended if:
- You have a threshold injury and are seeking damages
- You believe the insurer has incorrectly assessed your fault or income loss
- You are disputing a decision about treatment and care benefits
- You have ongoing symptoms that were not initially recorded
SIRA provides a formal review process for disputed decisions. You must request a review within 28 days of receiving the decision. The review is conducted by SIRA’s internal review team, and you may be required to provide additional evidence.
Hypothetical example: A roundabout collision in Ballina
A 38-year-old cyclist was struck by a car while crossing a roundabout in Ballina. The driver claimed they did not see the cyclist, but a witness reported the car had slowed but did not stop. The cyclist sustained a whiplash injury and was diagnosed with a cervical spine soft tissue injury. Medical records showed neurological signs consistent with a spinal nerve-root injury, but not radiculopathy.
The claimant submitted a police report, photographs of the scene, and a medical report confirming the injury. SIRA accepted the claim and approved treatment and care benefits. Because the injury met the threshold under the Motor Accident Guidelines, the claimant was also eligible for damages. The claim was not barred by the 52-week rule because the injury was not the only one sustained.
