Vehicles operating under a mass or dimension exemption (notice or permit) in South Australia must travel within stated areas and on stated routes.
About the National Network Map
The National Heavy Vehicle Regulator (NHVR) publishes all South Australian heavy vehicle maps on the National Network Map.
The National Network Map is the authoritative location for the heavy vehicle industry to plan journeys within and across participating Australian states and territories.
This NHVR-led initiative aims to improve heavy vehicle access efficiency and decision-making by bringing together the state-based heavy vehicle networks and displaying them in one location.
The interactive mapping system allows you to see what conditions and restrictions that apply across the country.
Help and support is available in the National Network Map, including video tutorials and in-system tour of features.
Contact NHVR if you need help or have questions about the map:
- Phone: 13 NHVR (13 64 87)
