The National Heavy Vehicle Inspection Manual (NHVIM) provides authorised officers and industry with consistent criteria for heavy vehicle inspections. The use of the NHVIM will ensure a nationally consistent approach to improve vehicle standards compliance and help reduce vehicle downtime.
Publication of the NHVIM provides inspectors and operators access to the same standards and criteria for which vehicles will be inspected nationally. Developed with extensive industry consultation, all participating states and territories have adopted the NHVIM into their inspection regimes.

In Queensland, South Australia and Tasmania there are additional inspection criteria for certain vehicles due to legislation outside of the Heavy Vehicle National Law.
Queensland - Vehicle mounted lifting systems fitted to heavy vehicles and inspected in Queensland are subjected to additional requirements as listed in Appendix Q – Stabilisers/outriggers mounted on heavy vehicles (PDF, 351KB)
South Australia - Every bus registered in South Australia must also comply with the Code of Practice for Buses which can be downloaded from www.sa.gov.au/topics/transport-travel-and-motoring/motoring/vehicles-and-registration/vehicle-types-and-specifications/code-of-practice-for-buses
Tasmania - There are additional vehicle requirements for buses, motorhomes, caravans and campervans used on Tasmanian roads as detailed in the National Heavy Vehicle Inspection Manual - Tasmanian Supplement which can be downloaded from www.transport.tas.gov.au/vehicles/vehicle_inspections/ais/ais_inspection_manuals

Heavy vehicle standards and the NHVIM
The Heavy Vehicle National Law (HVNL) requires that all heavy vehicles used on a road must comply with heavy vehicle standards (s60). Use of a heavy vehicle on a road that does not comply with the standards can result either in the issue of an infringement or the issue of a defect notice.
The heavy vehicle standards, which include both the requirements of the Australian Design Rules (ADRs) and the Heavy Vehicle (Vehicle Standards) National Regulation, are detailed technical standards that set out the minimum safety, emissions and anti-theft requirements that apply to heavy vehicles. While quite detailed and comprehensive, these standards are technical documents and are often not easily read or applied by inspectors, operators or drivers. To assist industry understand the heavy vehicle standards and understand when a vehicle may not comply, the NHVR publishes the NHVIM. The NHVIM also details practical information about wear, damage or change to important systems as a result of their in-service use.
While the NHVIM is not referenced in the HVNL, each of the reasons for rejection included is linked to a heavy vehicle standard. For example, the reasons for rejection outlined in Section 3 Couplings of the NHVIM can be directly related back to a requirement of either the national regulation or ADRs 62 or 63.
Furthermore, while the NHVIM comprehensively summarises the requirements of the heavy vehicle standards, it is not exhaustive and must be read in conjunction with both vehicle and component manufacturer’s specifications.
The criteria set out in the NHVIM reflect current consultation with road user groups, road transport authorities, police agencies, manufacturers and suppliers.
A consistent national standard for heavy vehicle roadworthiness
The development and implementation of the NHVIM as the national standard for vehicle inspections is the first part of the National Heavy Vehicle Roadworthiness Program. The program is a national initiative that seeks to improve the roadworthiness of the heavy vehicle fleet by taking a risk-based approach for auditing, monitoring and inspecting heavy vehicles.
