How SIRA Determines Fault in Rear-End Collisions

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).

In New South Wales, the Motor Accident Injuries Act 2017 (MAIA) governs Compulsory Third Party (CTP) claims. SIRA (State Insurance Regulatory Authority) assesses rear-end collision claims by determining fault based on the 'duty of care' principle. Typically, the driver who struck the vehicle in front is deemed at fault unless there are exceptional circumstances, such as a sudden stop or mechanical failure. SIRA evaluates fault by examining evidence like police reports, witness statements, and the circumstances of the accident.

Evidence Needed for a Successful Claim

To support a rear-end collision claim, you must provide:

  • A police report documenting the accident
  • Medical records confirming injuries
  • Witness statements or contact details
  • Photographs of the damage
  • Proof of income if claiming weekly payments

SIRA prioritizes medical evidence to assess injury severity. For example, if you sustained a soft-tissue injury (like a whiplash), your doctor must confirm it meets the 'threshold injury' criteria outlined in the Motor Accident Guidelines. This ensures your claim aligns with the scheme’s requirements.

Time Limits and Medical Assessments

CTP claims must be submitted within 52 weeks of the accident, unless an extension is granted. SIRA requires medical assessments to determine if your injuries qualify for benefits. If your injuries are below the threshold, you may still claim treatment and care benefits, but weekly payments are limited after 52 weeks. For example, if your only injuries are soft-tissue, you’ll receive treatment benefits for 52 weeks, after which you may no longer qualify for weekly payments.

When to Seek Legal Advice

If your claim is denied or you’re unsure about your entitlements, seek legal advice. SIRA’s Ballina office may take time to process complex cases, especially if there are disputes over fault or injury severity. A legal professional can help you understand your options, including disputing a decision or exploring additional remedies.

Practical Example

Imagine you were rear-ended at a Ballina intersection. The police report notes you were stationary, and the other driver failed to stop. SIRA would likely find the other driver at fault. If your doctor confirms a soft-tissue injury, you could claim treatment benefits for 52 weeks. However, if your injuries are minor and don’t meet the threshold, you may not qualify for weekly payments.

Next Steps

CTP claims depend on the accident date, injury type, and evidence provided. To request contact about your circumstances, complete the quick, no obligation enquiry form.
