National Heavy Vehicle Inspection Manual
The National Heavy Vehicle Inspection Manual (NHVIM) is a document developed by the National Heavy Vehicle Regulator (NHVR) to establish a single national approach for ensuring heavy vehicle roadworthiness. It applies to all vehicles with a gross vehicle mass or aggregate trailer mass greater than 4.5 tonnes and details practical information regarding wear, damage, or changes to important systems.
The purpose is to provide authorised officers and approved vehicle examiners with a nationally consistent set of failure criteria for heavy vehicle inspections.
It applies to all heavy vehicles that have a gross vehicle mass or aggregate trailer mass greater than 4.5 tonnes.
Vehicle Standards, including ADRs and original manufacturer specifications, take precedence over the requirements of the NHVIM.
