What are the HVNL speed compliance duties?
Short answer
Drivers must obey applicable speed limits, and businesses must ensure their transport activities, requests and contracts do not cause or encourage a heavy-vehicle driver to speed.
Plain English
Speeding is not only a driver issue. Under the Primary Duty, each Chain of Responsibility party must eliminate or minimise the public risks from the transport activities it controls or influences and must not cause or encourage a driver to exceed a speed limit.
Section 26E separately prohibits a person from making a request, direction or requirement, or entering a contract, that the person knows or ought reasonably to know would cause or encourage speeding. Unrealistic delivery windows, loading delays, poorly designed time slots, incentives and payment arrangements can all create speed risk.
What this means operationally
Plan routes and schedules with lawful travel, rest, traffic, weather, loading and queuing time; provide a safe escalation process for delays; review contracts and incentive structures; monitor speed information in context; investigate patterns and correct the system rather than merely warning the driver. Never use a speed limiter as the only control.
Who it applies to
Drivers under the applicable road rules and all Chain of Responsibility parties, executives and other people making requests or contracts that can influence heavy-vehicle speed.
Example
A customer sets a delivery slot that cannot be met without speeding after predictable loading delays. The scheduler and customer must change the slot or transport plan rather than leave the driver to absorb the risk.
Exceptions and traps
A late delivery, customer penalty or missed slot is not a defence to speeding. Telematics can support risk management but a single data point needs proper investigation, and fitting a compliant speed limiter does not remove scheduling, contracting or Primary Duty obligations.
What changed
The risk-based Primary Duty has applied since 1 October 2018. The 1 August 2026 amendments updated s 26E for fatigue and fitness-to-drive wording, while its prohibition on causing or encouraging speeding remains.
Previous rule
Before the 2018 Chain of Responsibility reforms, speed obligations were framed through more prescriptive speed-compliance duties rather than the current overarching Primary Duty model.
Legal foundation
Heavy Vehicle National Law ss 26C and 26E and s 93 for speed-limiter tampering; applicable state or territory road rules and speed limits

Frequently asked questions
Is speeding only the driver's responsibility?
No. Businesses and other parties must not create or encourage speed risk through their transport activities, requests or contracts.
Can a delivery contract create an offence?
Yes, if a person knows or ought reasonably to know it would cause or encourage the driver to speed.
What should a scheduler allow for?
Lawful travel, rest, traffic, weather, loading, queuing and realistic delay recovery.
Is a speed limiter enough?
No. It does not replace safe schedules, contracts, monitoring, investigation and other risk controls.
What should happen after a speed alert?
Investigate the data and surrounding work system, address the immediate event and correct any recurring cause.
