The Heavy Vehicle National Law and Chain of Responsibility, in plain words
The HVNL applies to vehicles over 4.5 tonnes in every state and territory except Western Australia and the Northern Territory. It does not prescribe a daily check. It asks every party in the chain to ensure safety so far as reasonably practicable, and the expectation of a daily check becomes concrete through accreditation, the Master Code, WHS prosecutions and contracts.
The primary duty (section 26C)
Every party in the chain of responsibility must ensure the safety of its transport activities so far as reasonably practicable. The NHVR says the vehicle owner has the greatest influence over maintenance and continued roadworthiness, and failing to maintain vehicles over time has been prosecuted as a primary duty breach.
Executive due diligence (section 26D, strengthened from 1 August 2026)
Executives owe a due diligence duty for the primary safety duty. From 1 August 2026 that duty is explicit, and a safety management system audit is admissible in court. The practical question an executive will be asked is whether there was a system for daily checks, fault reporting and timely repair, and whether it was used.
Chain of Responsibility
Consignors, packers, loaders, schedulers, operators and drivers all carry the duty. A light fleet business that consigns, packs, loads or schedules heavy vehicles is in the chain even though its own vehicles sit below 4.5 tonnes.
The Master Code and the Vehicles as a Workplace guide
A registered industry code is evidence of what is reasonably practicable, and the NHVR uses the Master Code as the benchmark in investigations. The 2026 edition was released on 21 January 2026. A separate Waste and Recycling Industry Code was registered in June 2024.
Under the WHS Act a vehicle used for work is a workplace and plant, which applies to light vehicles as well. Escudo Fleet is designed with the Master Code and the Vehicles as a Workplace guide in mind.
Defect notices
Notices come as major, minor and self-clearing. The NHVR reported fines of A$5,000 and A$17,000 in 2026 for using vehicles contrary to uncleared notices, and says operators should have policies for reporting and actioning defect and other statutory notices.
Western Australia and the Northern Territory
Both sit outside the HVNL. WA runs its own accreditation with a maintenance module that mirrors NHVAS: a daily check for each vehicle including trailers, with the person acknowledging roadworthiness within the limits of inspection. No daily check rule was found for the NT.

What Escudo Fleet keeps for this
- A daily check per vehicle with the driver identified, stamped at the moment of the check, against the template version in force that day
- Faults with who found, assessed, deferred or cleared them and when, with photos, and the qualification and test note when a safety critical fault is cleared
- A defect notice register with date, place, defect, deadline, repairer and clearer
- An append-only audit log, so the record shows what was known and when
- A PDF evidence pack per vehicle and date range, from the first fault to the repair
- An incident and near-miss register, reported from the phone with photos, other parties and a sketch. Records only: Escudo never decides whether an incident must be reported
- A weekly digest of checks missed, open faults, expiries and services due, with who has pressed "I have read this" each week
Escudo Fleet helps you show a system of work for daily checks, fault reporting and timely repair. It does not make a business compliant with the HVNL, and no software can. The record is yours, and what it proves is up to you.
Fleets this applies to
- Waste and recycling: Compactors, side loaders, rear loaders, hook lifts and street sweepers.
- Bus and coach: School buses, route services, charter and coach operators.
- Truck and freight: Rigids, prime movers, trailers and B-doubles, local and line haul.
- Courier and last mile: Vans and light trucks, franchise networks and subcontractor drivers.
- Trades and service fleets: Utes, vans, trailers and plant for builders, electricians, plumbers and service crews.
- Hire fleets: Car, van, truck and plant hire, and company pool vehicles.
- Councils: Depot fleets of trucks, plant, utes, pool cars and contractor vehicles.
