Roadworthiness Program

The Roadworthiness Program is a package of eight projects being delivered by the NHVR on behalf of Transport and Infrastructure Council (TIC).

The objective of the program is to reduce the social, environmental and economic impacts resulting from unroadworthy heavy vehicles by changing industry behaviour to ensure they proactively maintain and operate their vehicles adhering to the heavy vehicle safety standards.

The program is being undertaken to implement a risk-based approach for ensuring compliance to vehicle standards by auditing, monitoring and inspecting heavy vehicles on a common basis.

National Roadworthiness Baseline Survey (NRBS)

The objective of the project was to gather sufficient information about the Australian heavy vehicle fleet to judge the standard of roadworthiness and identify causal factors that will result in adverse impacts.

The project was undertaken to provide a national baseline for the condition of the heavy vehicle fleet against which future reform initiatives can be measured.

The data will inform the development of policies developed as part of the implementation of a risk-based inspection regime. Read more ...

Roadworthiness Data Collection

The objective of the project is to cost effectively identify and collect data that can be used to:

  • assess the performance of heavy vehicle inspections in addressing the consistency of vehicle safety standards; and
  • manage the allocation of scarce inspection resources (people, facilities and equipment) to delivering the greatest benefit in reducing impacts.

The project will also identify what data is required to manage the assessment of the efficiency and effectiveness of Inspections in reducing impacts caused by unroadworthy heavy vehicles.

Roadworthiness Criteria

The objective of the project is to develop a consistent, risk-based methodology for assigning a particular vehicle issue (component or system) to an enforcement outcome.

This will ensure that the severity of a defect issued correlates with an evidence-driven, risk assessment of the issue with a vehicle component or system which resulted in the defect notice, to achieve improved national consistency and efficiency of the inspection regime.

Inspection Types

The objective of the project is to provide consistently applied guidance on standardised inspection types that can be applied as required to verify whether the vehicle components and systems are at a standard that does not result in excessive impacts.

The project is being undertaken to guide Inspectors on the extent of an inspection they should conduct and to ensure a common approach to inspection and to the recording of TMR inspect results.

Inspection Competency Standards

The objective of the project is to establish the minimum competencies for Inspectors to undertake the different Inspection Types that determines the standard of vehicles safety.

The project is being undertaken to ensure Inspections are conducted by Inspectors with the required competencies which they will apply to assess vehicle safety to a common standard.

Management and Clearance of Defects

The objective of this project is to develop a nationally-consistent approach for the recording and clearance of defects.

To achieve national consistency on defect clearing, including clearance of defects by inspection by suitable persons outside of the issuing jurisdiction.

National Risk-Based Inspection Criteria

The aim of this project is to bring together all the elements of the National Heavy Vehicle Roadworthiness Program into a cohesive framework for the identification, frequency, selection and method of inspection for heavy vehicles utilising a risk-based criteria (matrix).

The risk-based criteria will guide the NHVR on what, when, why and how heavy vehicles are targeted rated on the impact they pose.

National Heavy Vehicle Inspection Manual (NHVIM)

Developed with extensive industry consultation, the National Heavy Vehicle Inspection Manual (NHVIM) provides a single, consistent national standard for heavy vehicle inspections.
