An NHVR audit is more than just paperwork — it’s how the National Heavy Vehicle Regulator (NHVR) ensures that your business is running safe, compliant systems under the National Heavy Vehicle Accreditation Scheme (NHVAS).

There are different types of NHVR audits you should know about:

• Entry Audit – conducted at the very beginning of your accreditation.
• Initial Audit – conducted 6 months after accreditation begins to confirm your systems are working in practice.
• Compliance Audit – required every two years to maintain accreditation.
• Spot Audit – an unannounced audit conducted at any time.
• Triggered Audit – conducted if a serious event, breach, or incident occurs.

Being prepared for all five audit types is critical to keeping your accreditation, protecting contracts, and staying on the road legally.

Here are the 10 essential things you should check today.

1. Current NHVAS Manual and Policies

Your NHVAS compliance manual must:

• Be current, version controlled, and consistent across all sites.
• Match the latest NHVR Business Rules & Standards.
• Be available at all depots, workshops, and locations where accredited vehicles operate.

Outdated or inconsistent manuals are one of the causes of non-conformance during audits.

2. Vehicle Register Accuracy

Every accredited operator must keep a vehicle register with:

• Vehicle make, model, type of unit, and year of manufacture.
• VIN/unique ID and rego (including state).
• Tare, GVM, GCM or ATM.
• Owner details (including subcontracted vehicles).
• NHVAS label number and scheme entry/exit dates.

Subcontracted vehicles must also appear on the register, with evidence that they comply under your accreditation.

3. Daily Vehicle Check Records

Auditors want to see proof that daily vehicle inspections are actually happening. Records must show checks of:

• Tyres, wheels, and rims.
• Lights and reflectors.
• Mirrors, windows, and wipers.
• Brakes, couplings, leaks, and bodywork integrity.
• Presence and condition of NHVAS label.
• Etc. — all items necessary to demonstrate that the vehicle is roadworthy before use.

These checks can be recorded on paper or electronically, but they must be retrievable and legible.

4. Fault Reporting and Repairs

Your fault management process must show:

• When, where, and how a fault was detected.
• Who reported it and who was responsible for repair.
• How the fault was prioritised (critical vs minor).
• Repair details and close-out date.
• Suspension or defect notices logged and tracked to completion.

Every step must be documented so there is no gap between fault discovery and closure.

5. Maintenance Schedules and Annual Inspections

Your maintenance management system must prove that vehicles are maintained to a safe, roadworthy standard:

• Service schedules that meet or exceed manufacturer intervals (time and kilometres).
• A table of tolerances and wear limits for safety-critical components.
• A documented annual mechanical inspection for every nominated vehicle, recorded using the NHVR Heavy Vehicle Inspection Checklist (or equivalent).
• Inspections and servicing must be done by a qualified mechanic. If work is completed in-house, you must keep a copy of the mechanic’s qualifications on file for audit purposes.

This demonstrates that your fleet is maintained properly and inspected by competent people.

6. Mass Management Trip Records

If you operate above General Mass Limits (GML), your trip records must include:

• Vehicle registration or fleet number.
• Date of trip.
• Loading and destination locations.
• Established axle and gross mass (from weighbridge/scales).
• Name of loader or loading company.
• Any breaches recorded in a contraventions register.

Auditors will use these trip sheets to verify that your system controls vehicle mass and complies with NHVR rules.

7. Mass Verification

You must regularly confirm that your loading system works. At least twice per year, loaded vehicles must be weighed using a certified weighbridge or calibrated portable scales (calibration within 12 months).

This proves that estimated loading methods are accurate and that axle/gross limits are not exceeded.

8. Suspension Maintenance Records

A suspension defect register must show:

• Vehicle rego and VIN.
• Date, time, and place of defect notice.
• Contravention details.
• Repairer name, date, and method.
• Clearance authority details.

This helps auditors confirm that suspension faults are being monitored, prioritised, repaired, and closed out properly.

9. Fatigue Management Training and Medicals

For BFM or AFM Fatigue Management accreditation, you must demonstrate:

• Drivers hold TLIF0005 – Apply a Fatigue Risk Management System.
• Schedulers hold TLIF0006 – Administer a Fatigue Risk Management System.
• Certificates are from an NHVR-approved RTO.
• Driver medicals are current in line with Assessing Fitness to Drive standards.

Auditors may also review rosters, schedules, and work diaries/EWDs against fatigue management rules.

10. Internal Reviews and Quarterly Compliance Statements

Your business must show active monitoring by:

• Completing annual internal reviews for each module.
• Preparing quarterly compliance statements (signed by a responsible officer).
• Retaining records for at least three years.

Auditors use these documents to confirm that your accreditation is being actively managed, not just documented.

Common Non-Conformances in NHVR Audits

The most frequent findings include:

• Manuals out of date or inconsistent across depots.
• Incomplete or inaccurate vehicle registers.
• Daily checks performed but not recorded.
• Faults reported but not closed out.
• Missing qualified mechanic evidence for servicing.
• Trip sheets missing axle or gross mass records.
• Expired driver medicals or missing TLIF training.

Final Thoughts

NHVR audits are a normal part of life for accredited operators. They ensure your systems for Mass Management, Maintenance Management, and Fatigue Management are working in practice — not just on paper.

By covering the above, your business will be well prepared for an Entry Audit, Initial Audit, Compliance Audit, Spot Audit, or Triggered Audit.
