The National Heavy Vehicle Regulator (NHVR) publishes materials to provide advice and guidance on how to do business with us and comply with the Heavy Vehicle National Law (HVNL). We are aware that on occasion, businesses imply a connection or affiliation with a government agency by way of the presentation and wording of their advertising material, where no such connection exists. If you are uncertain of whether an entity has a legitimate connection with the NHVR, please contact us to discuss, before dealing with them.
