HVNL Chain of Responsibility: A Checklist for Shippers

Under the Heavy Vehicle National Law (HVNL), Chain of Responsibility (CoR) spreads accountability for safe heavy-vehicle operation across every party in the chain — not just the driver and the operator. If you’re a shipper, consignor, packer, loader, scheduler or consignee, CoR applies to you. This post is a practical checklist for shippers: what you must verify, what you must record, what you must avoid.

Who CoR applies to

HVNL Chain of Responsibility applies to anyone who, in the course of their work, exercises — or has the capacity to exercise — control or influence over a heavy vehicle’s use. The named parties include:

• The consignor (you, if you’re sending the freight)
• The packer (whoever puts the load together)
• The loader (whoever puts the load on the vehicle)
• The scheduler (whoever sets pick-up / delivery times)
• The operator (the transport company)
• The driver
• The consignee (whoever receives the freight)

The shipper’s primary duty

The HVNL puts a primary duty on every party: ensure the safety of your transport activities, so far as is reasonably practicable. For a shipper that means: don’t schedule the impossible, don’t overload, don’t mis-declare, don’t pressure the driver to break fatigue rules, and don’t look the other way.

The shipper’s CoR checklist

1. Mass and dimensions

• Calculate weight per pallet and per consignment before booking the load
• Match the load to the trailer’s legal capacity (single-pan, B-double, oversize)
• Don’t book on knowingly incorrect declared weights
• Keep records: weighbridge dockets, manifest, consignment notes

2. Load restraint

• Pack to comply with the National Transport Commission’s Load Restraint Guide
• Cross-check restraint at the loader stage; don’t hand off responsibility blindly
• If a load can move, restrain it; if it can fall, secure it; if it can leak, contain it

3. Driver fatigue

• Don’t schedule pick-ups or deliveries that force a driver to exceed work or rest hour limits
• Build realistic transit times into your bookings — legal hours, not optimistic hours
• Ask your operator which fatigue management module they hold (Standard, BFM or AFM)

4. Speed

• Don’t set delivery windows that can only be hit by speeding
• If the booking implies an illegal average speed, the booking is wrong

5. Vehicle standards

• Use operators who maintain their fleet to NHVAS Maintenance Management standards
• Don’t book operators you know to run unsafe equipment

6. Documentation

• Keep manifest, consignment note, weighbridge docket, and any temperature certificates
• Retain records consistent with HVNL evidentiary expectations

What “reasonably practicable” means

The HVNL doesn’t require perfection. It requires you to do what’s reasonably practicable to manage the risks. That means using competent operators, asking the right questions, keeping records, and stopping a job that’s clearly going to break the law.

Working with an NHVAS-accredited operator

Choosing an NHVAS-accredited transport operator simplifies the CoR conversation. They have an audited fatigue, mass and maintenance regime; you can rely on their compliance evidence; you have one more layer of risk management between your warehouse and the road. DRT Logistics is NHVAS-accredited under all three modules — Basic Fatigue Management, Mass Management and Maintenance Management — and AMCAS-accredited under the Master Code of Practice.
