The following description was taken from Glossary of common terms by NHVR :
This glossary is intended to assist anyone who would like to understand common terms used in the heavy vehicle industry. The terms and definitions provide a single common reference point. Entries are organised alphabetically and, where relevant, the source of the definition is referenced. A list of acronyms is provided in Section 2, while the detailed list of terms can be found in Section 3. Terms used in this glossary do not supersede or replace those in the Heavy Vehicle National Law (HVNL) but are meant to help users develop a common understanding of terminology particular to the heavy vehicle industry.
In developing this Glossary, the following references have been used:
- Heavy Vehicle National Law (HVNL)
- Heavy Vehicle National Regulations
- Austroads Glossary of Terms.
Definitions for which a source is not provided have been drafted by the NHVR for the sole purpose of this Glossary.
These definitions have been drafted using existing policy documents and guidelines issued by the NHVR.
