What does S1-4 require?

Operating limits are what distinguish ACA fatigue: rather than resting on prescriptive hours alone, the limits are built around the particular fatigue risks of the operator's work, allowing for the nature and length of tasks, the recovery periods needed, cumulative fatigue across sequences of work, and the way time of day affects fatigue and sleep. Approved limits are watched and reviewed as operations change, and any exceedance in defined circumstances happens inside a controlled framework with countermeasures and oversight. Five things are looked for: limits reflect the applicant's own fatigue risk profile and operating context; they allow for task demands, recovery, cumulative fatigue and time of day; they are monitored and reviewed so they stay suitable; exceedances are controlled, justified and backed by countermeasures; and work and rest records are checked to confirm compliance with the approved limits.

Other controls in Schedule 1 Alternative compliance accreditation, fatigue (requirements 2 to 10) – Australia Heavy Vehicle National Law Safety Management System Standard 2026

S1-10 ACA fatigue, evidence: documented and controlled fatigue policies, procedures and instructions that are current and accessible, records demonstrating compliance with operating limits, implementation of controls, training and competence, and review and corrective action outcomes, with records that credibly reflect actual operations and are retained in a form and for a period supporting oversight
S1-2 ACA fatigue, responsibility and accountability: fatigue authorities and responsibilities defined and assigned, senior management exercising informed judgement with visibility of fatigue intelligence such as breach rates and roster variances, non-reprisal reporting of fatigue and incidents, and information exchange between drivers and leadership
S1-3 ACA fatigue, scheduling and rostering: rosters and schedules compliant with approved alternative compliance hours, documented, monitored and reviewed, planned so work is safe within operating limits under foreseeable conditions, with processes for schedule changes, extended work and unplanned events, driver scope to adjust for rest, and exceedances only in defined circumstances within approved limits with countermeasures
S1-5 ACA fatigue, technology-enabled controls: where fatigue technology is used it is integrated into the fatigue management system, supports rather than replaces effective practice and oversight, and does not diminish operator accountability
S1-6 ACA fatigue, fitness for duty, health and wellbeing: medical certification under Austroads Assessing Fitness to Drive including sleep disorder assessment at least every three years to age 49 and annually from 50, additional in-service assessment where indicated, driver self-assessment and notification, consideration of lifestyle, health and medical advice in work allocation, promotion of health and wellbeing, and specific arrangements for two-up driving and overnight vehicle rest
S1-7 ACA fatigue, workplace and vehicle conditions: cabins and sleeper berths that support comfort and restorative rest, facilities for recovery away from home, compliance with safety and vehicle standards affecting fatigue, and additional controls where drivers sleep in vehicles away from home
S1-8 ACA fatigue, training and competency: fatigue knowledge for all personnel in the fatigue system, demonstrated competence with TLIF0030 (drivers) and TLIF0031 (schedulers and supervisors) or an equivalent or a pre-July 2018 recognised qualification, fatigue responsibilities in inductions, refresher and reactive training after fatigue incidents, and verified application in the operating environment
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
