What does S3-5 require?

Suspension systems are critical to mass compliance and road infrastructure protection, so the operator ensures suspensions on all relevant vehicles, trailers and third-party vehicles included, are maintained and repaired to appropriate technical standards reflecting manufacturer specifications or qualified professional advice and, where applicable, industry codes or inspection manuals; the system supports timely identification, reporting and repair of suspension faults with prioritisation of serious defects, and clear decision-making and sign-off ensure repairs are completed and verified before vehicles continue under accreditation, with evidence giving confidence that other parties' vehicles meet the standard. The criteria: suspension systems on accredited vehicles are maintained to appropriate technical standards and specifications; suspension faults are identified, reported, prioritised and repaired so as to manage mass risk; repairs and maintenance are done by suitably qualified or supervised persons; suspension maintenance and repair decisions have appropriate oversight and sign-off; and for vehicles supplied by other parties the operator holds evidence that suspension maintenance meets the standard before they operate under the accreditation.

Other controls in Schedule 3 Alternative compliance accreditation, mass (requirements 2 to 9) – Australia Heavy Vehicle National Law Safety Management System Standard 2026

S3-2 ACA mass, responsibility and accountability: mass management responsibilities allocated across management, operation and verification, leadership visibility of mass risks such as overload incidents and equipment failure, responsibilities actively discharged with governance visibility of compliance outcomes, and leadership oversight of workforce capability for mass tasks
S3-3 ACA mass, vehicle identification and capability: all vehicles and trailers under the accreditation identifiable at any time, current documented details including subcontractor vehicles sufficient for audit, information showing identity, configuration and applicability of mass concessions or authorisations, vehicles demonstrably capable of operating within axle and gross mass limits, current network access authorisations, and controls securing subcontractor vehicles to the operator's accreditation
S3-4 ACA mass, vehicle use: mass determined before departure by a method giving objective assurance of compliance with axle and gross mass limits, loading decisions based on defined repeatable methods rather than estimates, foreseeable variation in density, volume, quantity and distribution accounted for, no trip commencing until compliance is confirmed, and records of suspension-related regulatory non-conformance
S3-6 ACA mass, verification: the accuracy of mass assessment methods periodically confirmed against certified or calibrated means producing auditable evidence, or, where periodic re-weighing is not relied on, demonstration that loading controls consistently ensure axle and gross mass compliance for every load and trip, with verification sufficient for confidence in the mass management system
S3-7 ACA mass, training and competence: persons with mass responsibilities understand the policies, procedures and instructions for their roles and why they exist, training appropriate to responsibilities and mass risks, evidence that training was delivered and competence maintained as systems or conditions change, and training that supports consistent application of mass controls
S3-8 ACA mass, review and continuous improvement: monitoring of weighbridge, onboard scale and load plan variance data to confirm consistent control, pattern detection prompting changes to loading instructions or calibration, corrective action at underlying causes rather than blaming loaders, reviews at intervals appropriate to risk and scale including quarterly oversight and annual assessment, demonstrated effectiveness of changes, and documented communicated procedure changes
S3-9 ACA mass, evidence: trip logs, weighbridge dockets or load plans credibly reflecting actual mass determinations and showing compliance for trips above general mass limits, evidence identifying the vehicles and the mass determination method per trip, current information on vehicles and personnel with mass responsibilities (integrable with existing records), evidence of action on mass defects and infringements, and documentation accessible and understandable to those who need it
