How SIRA Handles Partial Fault in NSW CTP Claims

If you were injured in a motor accident where more than one driver contributed to the crash, you may be eligible for compensation under NSW’s Compulsory Third Party (CTP) scheme. The New South Wales Motor Accident Injuries Act 2017 and SIRA’s guidelines determine how fault is split between drivers and how this affects your claim. This article explains how SIRA assesses shared liability in partial fault claims, focusing on practical implications for claimants in Bankstown.

SIRA’s Approach to Partial Fault Claims

Under NSW law, SIRA (State Insurance Regulatory Authority) oversees claims under the CTP scheme. When a crash involves multiple parties, SIRA uses a contributory negligence approach to determine how fault is divided. This means the court or SIRA assesses the degree to which each driver contributed to the accident. For example, if Driver A ran a stop sign and Driver B was speeding, SIRA might allocate 60% fault to Driver A and 40% to Driver B.

SIRA’s guidelines state that fault is split based on objective evidence, such as police reports, witness statements, and expert analysis. The goal is to ensure claimants receive compensation that reflects the proportion of fault attributed to each party. This process is distinct from common law claims, where fault is determined by a court.

How Shared Liability Affects Compensation

In partial fault claims, the amount of compensation you receive depends on the fault split. SIRA applies a reduction factor to your claim based on the percentage of fault attributed to you. For example:

  • If you are 20% at fault, your compensation is reduced by 20%.
  • If you are 50% at fault, your compensation is reduced by 50%.

This reduction applies to all benefits, including weekly income payments, treatment and care benefits, and lump sum damages. However, SIRA’s rules do not apply to claims involving Nominal Defendant cases, where the driver is not identified.

Practical Steps and Evidence for Partial Fault Claims

To support your claim, you must provide evidence that demonstrates the fault split. Key documents include:

  • Police reports detailing the accident and fault allocation
  • Witness statements from parties involved
  • Expert reports from accident reconstruction specialists
  • Video footage or traffic camera evidence

In Bankstown, claimants should also note that local traffic conditions or road design may influence fault assessments. For example, a driver who ran a red light at an intersection may be deemed more at fault than a pedestrian who jaywalked.

Time Limits and When to Seek Advice

You have three years from the date of the accident to file a CTP claim under the Motor Accident Injuries Act 2017. However, delays can reduce your chances of securing a fair outcome. If you are unsure about fault allocation or how to calculate your compensation, seek legal advice promptly.

A Hypothetical Example

Imagine a Bankstown crash where Driver A (a car) and Driver B (a motorcycle) collided at an intersection. Police reports indicate Driver A ran a red light (60% fault) and Driver B failed to yield (40% fault). SIRA would reduce Driver B’s compensation by 40% to account for their share of responsibility. This ensures claimants are not unfairly penalized for accidents involving multiple contributors.

Next Steps for Claimants

If your claim involves shared liability, it is essential to:

  • Gather all available evidence of fault
  • Submit your claim to SIRA within three years of the accident
  • Seek legal advice if you are unsure about fault allocation or compensation calculations

Every claim depends on its own facts. To request contact about your circumstances, complete the quick, no obligation enquiry form.

Why Bankstown Matters

While SIRA’s rules apply statewide, local factors in Bankstown, such as traffic density, road conditions, or specific accident patterns, can influence fault assessments. Claimants should be aware that evidence from the local area may carry more weight in determining liability splits.

Conclusion

SIRA’s approach to partial fault claims ensures that compensation reflects the proportion of fault attributed to each party.
