Self-clearing defects from July 1

From July 1 self-clearing defects do not require an inspection of the vehicle by an approved person for the purpose of having the self-clearing defect notice cleared. For more information read Compliance bulletin 4 – Heavy vehicle defects (PDF, 96KB)

On-road compliance and enforcement

Under the Heavy Vehicle National Law (HVNL), on-road compliance and enforcement covers a broad range of activities including (but not limited to) the:

Heavy vehicle drivers and operators benefit from a greater level of consistency in on-road compliance and enforcement outcomes under the HVNL. For heavy vehicle drivers, no matter who conducts an inspection, or in which state or territory it is conducted, drivers and operators should experience consistent and transparent outcomes from on-road compliance and enforcement activities for:

  • Defective heavy vehicles - a consistent tiered vehicle defect notice categorisation scheme (self-clearing defect, minor, major and major grounded) and promoting more standardised defect notices
  • Driver fatigue and the National Driver Work Diary - consistent interpretation and application of driver fatigue and work diary requirements
  • Load restraint - consistent application of the National Transport Commission’s Load Restraint Guide
  • Mass and dimensions - a focus on applying measurement adjustments for all on-road inspections delivering consistent weighing and measuring assessments
  • Restricted access vehicles - uniform, national processes for on-road inspections of Class 1, 2 and 3 vehicles operating under mass or dimensions exemptions (notices or permits)

Before the introduction of the HVNL, on-road compliance and enforcement activities varied between states and territories. The NHVR worked collaboratively with state and territory road transport authorities and police agencies to harmonise a range of these processes under the HVNL with the aim of delivering consistent on-road compliance and enforcement, aiming for the same outcome in the same circumstances.

What stayed the same?

  • On-road compliance and enforcement activities across the country did not change significantly under the HVNL. For example, the processes for weighing, measuring, inspecting and assessing vehicles and drivers, largely remained the same.
  • Police officers continue to comply with other legislation that regulates their powers and responsibilities. Police officers may possess additional enforcement powers and responsibilities such as enforcing road rules. Police officers determine the necessary action for any on-road compliance and enforcement activity.
  • State and territory police, and enforcement officers continue to monitor heavy vehicle activities under the HVNL while legal and court processes largely remain the same as they were prior to the HVNL.
  • Matters relating to heavy vehicle registration, inspections, driver licensing and carriage of dangerous goods, remain with the relevant state or territory road transport authority.
