Driver fatigue accidents: How SIRA handles claims under NSW CTP laws

This article explains how SIRA evaluates driver fatigue accidents under NSW CTP laws, including the evidence required, how fatigue claims differ from other injury types, and practical steps for claimants. It clarifies that SIRA assesses whether fatigue *contributed* to the accident, not just occurred afterward.

Current as at 19 June 2026

Driver fatigue accidents are treated as contributing factors in NSW CTP claims, but SIRA's approach depends on how the fatigue relates to the accident. Under the Motor Accident Injuries Act 2017 (MAIA), claims must show the accident caused injuries, and fatigue is assessed as a potential contributing factor. SIRA evaluates whether the fatigue directly led to the collision or impaired the driver's ability to operate the vehicle safely. This article explains how SIRA interprets driver fatigue claims in Greater Sydney, the evidence required, and practical steps for claimants.

How SIRA assesses driver fatigue claims

  • SIRA does not automatically assume fatigue is a claimable factor. Instead, it requires evidence that the driver's fatigue
  • contributed* to the accident. For example, if a driver fell asleep at the wheel and crashed, SIRA would assess whether the fatigue was a
  • causal factor* in the collision. This is different from claims where the driver was injured in a collision but not at fault.
  • Under the MAIA, claims must establish a
  • connection* between the accident and the injuries. SIRA uses the
  • Motor Accident Guidelines* to determine whether fatigue qualifies as a contributing factor. For instance, if a driver was drowsy and failed to notice a stop sign, SIRA would evaluate whether the fatigue impaired their ability to react in time.

Evidence required for fatigue-related claims

To support a driver fatigue claim, claimants must provide:

  • Medical evidence: A doctor's report confirming the driver was fatigued at the time of the accident. This could include sleep disorder diagnoses or records of drowsiness.
  • Accident reports: Police or witness accounts showing the driver was unresponsive, drifting, or showed signs of drowsiness (e.g., lane weaving).
  • Witness statements: Testimony from others who observed the driver's behavior before the collision.
  • Vehicle data: If available, dashcam footage or telematics showing erratic driving patterns.
  • SIRA does not accept claims where the fatigue was a
  • consequence* of the accident, not a
  • contributing factor*. For example, if a driver became fatigued after the collision, that would not qualify.

How SIRA's approach differs from other injury types

SIRA treats fatigue claims differently from injuries caused by other factors, such as road conditions or other drivers. In fatigue cases, the focus is on whether the driver's state of alertness impacted their ability to operate the vehicle safely. This is distinct from claims where the driver was injured in a collision but not at fault.

For example, if a driver was injured in a collision caused by another vehicle, SIRA would not consider fatigue as a claimable factor. However, if the driver was drowsy and failed to notice a hazard, SIRA would assess whether the fatigue directly contributed to the accident.

Practical steps for claimants

  1. Seek medical attention: Document any injuries and ensure a doctor records the driver's state of alertness at the time of the accident.
  2. Report the accident: Contact the police and obtain an accident report, as this can help establish the driver's condition.
  3. Gather witness statements: Ask witnesses to describe the driver's behavior before the collision.
  4. Notify SIRA: Submit a claim through SIRA's online portal, attaching all relevant evidence.
  5. Review the claim: SIRA may request additional information or ask for a medical report to confirm the fatigue was a contributing factor.

Time limits and disputes

Claims must be submitted within 5 years of the accident under the MAIA. However, SIRA may close a claim if it determines the fatigue was not a contributing factor. If a claimant disagrees with SIRA's decision, they can request a review or seek independent legal advice.

When to seek legal advice

SIRA's interpretation of fatigue claims can be complex, especially when the driver's condition overlaps with other factors (e.g., a medical condition causing drowsiness). A solicitor can help clarify whether the fatigue qualifies as a contributing factor and ensure all evidence is properly submitted.

Conclusion

Driver fatigue accidents in NSW are handled under the MAIA, with SIRA assessing whether the fatigue directly contributed to the collision. While SIRA does not automatically accept fatigue claims, proper evidence can support a claim.
