What is a heavy-vehicle defect notice?
Short answer
A heavy-vehicle defect notice is an enforcement notice identifying a vehicle defect and the restrictions, repair and clearance steps required before unrestricted use can resume.
Plain English
The HVNL recognises self-clearing, minor and major defect notices. The category reflects the assessed safety consequence and determines the restrictions and clearance process stated in the notice.
A self-clearing notice does not require a separate vehicle inspection, but it still must be cleared in the required way. A minor or major notice may restrict use, specify a repair period or require inspection and clearance. The exact notice controls what the vehicle may do.
What this means operationally
Read every notice immediately, isolate the vehicle if required, notify the responsible fleet and maintenance people, follow movement restrictions, repair the listed defects, retain evidence and complete the required inspection or clearance. Check that the notice is actually cleared before returning the vehicle to normal service.
Who it applies to
Heavy-vehicle owners, registered operators, drivers, fleet and maintenance managers, repairers and anyone controlling whether the defective vehicle is used.
Example
An authorised officer issues a major notice for a serious brake defect. The vehicle may be moved only as the notice permits, repaired and cleared through the required process before normal operation resumes.
Exceptions and traps
Booking a repair does not itself authorise driving. A vehicle may be moved only within the notice terms and other applicable law. Clearing the listed notice also does not excuse a different unsafe condition discovered during the repair.
What changed
The current tiered system uses self-clearing, minor and major categories. Operators should follow the category and instructions on the current notice rather than relying on older terminology or a previous defect process.
Previous rule
The lowest tier was previously referred to in some NHVR reporting as a formal warning before the self-clearing terminology was standardised.
Legal foundation
Heavy Vehicle National Law Part 9.3 Division 6, including ss 525-530, and the notice-specific requirements and movement restrictions

Frequently asked questions
What are the defect-notice categories?
Self-clearing, minor and major.
Does a self-clearing notice need an inspection?
Not a separate inspection, but the defect must still be repaired and the notice cleared as required.
Can I drive a vehicle with a major defect notice?
Only to the extent and in the circumstances expressly allowed by the notice and applicable law.
Who must arrange clearance?
The owner or operator should ensure repairs, evidence, inspection where required and formal clearance are completed.
Does clearing one notice prove the whole vehicle is safe?
No. Any other unsafe or non-compliant condition must also be addressed.
