The future HVNL should also adopt a risk-based approach to maintaining vehicles to ensure roadworthiness and safety over their lives

Chapter 11 of the RIS explains the options to better address roadworthiness.

Summary of problems and options

Improving roadworthiness assessment and defect clearance processes


Administrative processes for clearing a defect notice, after a defective vehicle has been repaired, can impose delays on the return of the vehicle with no risk to safety to the road. There is no defined defect clearance process under HVNL, however, the NHVR has issued guidance.

The guidance notes that a defect notice may instruct that the defect needs to be formally cleared by the registration authority before a repaired heavy vehicle can be returned to the road. Hence if defects are identified, the vehicle may need to be cleared by the registration authority in the State in which the defect was identified. This can result in significant and unnecessary delays for a repaired vehicle, particularly when it has been defected, and/or repaired in a state other than that in which it is registered.

Addressing inconsistencies in inspection regimes


There are inconsistencies in the way roadworthiness is managed across jurisdictions which relate to differences in jurisdictional inspection regimes. The inspection regimes between jurisdictions vary significantly. In many cases, neither the nature nor the frequency of these inspections is affected by the risk posed by the operation of the vehicle concerned.
