Heavy-vehicle operators transitioning from the National Heavy Vehicle Accreditation Scheme to Heavy Vehicle Accreditation need to work from their earliest module expiry date, not the date that is most convenient for the business.
The National Heavy Vehicle Regulator has confirmed that when an access arrangement, notice, permit or PBS Vehicle Approval requires accreditation, the operator must hold that accreditation at all times.
If it expires, the operator is no longer entitled to the benefit and should not continue operating under the affected arrangement until the required accreditation is reinstated.
That can affect Higher Mass Limits, some Performance-Based Standards operations and other notice or permit arrangements containing an accreditation condition.
The earliest module expiry usually controls the transition
Operators holding several NHVAS modules may have different expiry dates. The NHVR says the earliest expiry will typically determine when transition action is required.
The practical instruction is to list every module and every operation that relies on it, then complete the transition before the first relevant accreditation expires. The regulator also recommends considering alignment of modules to reduce repeated audits. Some operators with a current two-year NHVAS accreditation may be eligible for an extension supporting transition.
New accreditation types now go through HVA
Existing NHVAS accreditations remain valid during the transition period, but the old scheme is not open for adding a new accreditation type.
Since the updated Heavy Vehicle National Law commenced, new accreditation applications must be made through HVA. An existing NHVAS operator seeking an additional accreditation type must use the new scheme and follow the transitional arrangements.
Higher GML did not abolish Mass accreditation
The increase in General Mass Limits and removal of Concessional Mass Limits did not erase accreditation conditions attached to HML or other access instruments.
Mass accreditation remains required wherever a notice, permit, PBS approval or other access arrangement specifies it. Operators should not infer from the higher GML baseline that Mass accreditation is no longer relevant to their operation.
The first place to check is the actual document authorising the operation: the PBS Vehicle Approval, notice, permit or other access instrument. Read its conditions together with the vehicle and route requirements.
If the condition is unclear, the NHVR says the operator should seek clarification before operating, either from the regulator on 13 64 87 or from the relevant road manager.
A practical transition check
Before the next job is scheduled, an operator should be able to answer five questions:
- Which NHVAS modules does the business hold, and when does each expire?
- Which vehicles and freight tasks rely on each module?
- Does any HML, PBS, notice or permit document make accreditation a condition?
- Is the business adding an accreditation type that must now be obtained through HVA?
- Has transition been completed before the earliest accreditation-dependent operation reaches expiry?
The risk is not simply an expired certificate. It is continuing an operation after the legal condition supporting its mass or access benefit has fallen away.
