Heavy vehicle modifications

From 10 February 2014, the National Heavy Vehicle Regulator (NHVR) is responsible for the management of modifications to heavy vehicles in participating jurisdictions.

Queensland, New South Wales, Victoria, South Australia, Tasmania and the Australian Capital Territory are the participating jurisdictions from the commencement of the NHVR.

To answer the most commonly asked questions about modifications to heavy vehicles (gross vehicle mass of more than 4.5t), the department has developed a list of frequently asked questions and answers.

For any additional information about heavy vehicle modifications, please visit the National Heavy Vehicle Regulator website.
