Australia Heavy Vehicle National Law Safety Management System Standard 2026 S1-9: ACA fatigue, review and continuous improvement: monitoring of work and rest records, roster variances and driver feedback, review that detects patterns of rising fatigue risk, investigation of incidents and near misses for fatigue contribution, corrective action at underlying causes, outcomes fed into policies, rosters and training, and periodic reviews at intervals commensurate with risk

What does S1-9 require?

Structured internal review lets the operator verify that its fatigue management system works and find improvements: periodic review of practice against documented policies and operating limits, mechanisms to identify, report, investigate and record non-conformances, investigation of incidents for fatigue contribution, and corrective action to prevent recurrence, with ongoing monitoring including work and rest records rather than annual checks alone. The criteria: the operator monitors fatigue data including work and rest records, roster variances and driver feedback to verify controls operate as intended day to day; review processes detect not only clear non-conformances but patterns of increasing fatigue risk before an incident; incidents and near misses are investigated for the extent of fatigue contribution; corrective actions target underlying causes such as unreasonable scheduling or inadequate training rather than symptoms; monitoring and investigation outcomes update fatigue policies, rosters or training; and periodic reviews of the fatigue system run at intervals commensurate with the risk of the work and rest arrangements.
