This guide explains how to start a Network Update Request from an existing vehicle network in NHVR Go. It shows you how to move from viewing a network in read only mode into edit mode so that changes can be proposed. It also outlines how the Network Update Request is reviewed for safety and compliance with the Heavy Vehicle National Law (HVNL).

NHVR Go (NHVR Portal) account with Road Manager access.

Access to Access management in NHVR Go.

The network you want to change already exists and appears in your Vehicle networks list (see “Searching for an existing network”).

1. Open NHVR Go in your browser and log in with your Road Manager account.

2. From the menu, select Access management, then select Vehicle networks to open the Vehicle Networks table.

3. In the Vehicle networks table, locate the network you want to update and click the hyperlink under Vehicle Network Name to open it in view-only mode.

4. Once the network is open, look at the bottom of the left-hand panel and select Update Network.

5. Read the information displayed in the Network Update Request text boxes. These explain that:

a) All changes to networks are made through a Network Update Request.

b) Each request involves selecting road segments to be added, removed, or updated with conditions or restrictions.

c) Every Network Update Request is reviewed by the NHVR Access Policy team to ensure it does not contravene safety or the HVNL and to check for errors (for example missed segments or conditions).
​

6. After reading the information, enter a clear and meaningful name for the Network Update Request in the free text field. Choose a name that will be easy to recognise later (for example including location and purpose).

7. Confirm the creation of the Network Update Request (as prompted on screen).

8. Once the request has opened, check the left-hand panel: it now shows that the network is in Edit mode and displays information about the update request itself rather than the parent network. This indicates you are working inside a Network Update Request.
​

9. From here, you can begin using the network management tools (Pan and Select, Area, Route Selection, All in My Area of Responsibility) to select segments and propose changes as required.
​

Remember that a Network Update Request is a proposal only; no changes apply to the live network until the request is approved by the NHVR Access Policy team.

Choose a consistent naming convention (for example “Region – Road – Change type – Month Year”) if multiple people create Network Update Requests under the same road manager account. This makes it easier to find requests later.

If you cannot see the Update Network option, confirm that you have opened the network in view mode and that you have the correct permissions for that network.

If you intend to update several networks with the same changes, start with one network and complete this process; the duplication and cloning functions are available later from the workflow area.

Check your organisation’s internal guidance on who is authorised to initiate Network Update Requests.

If you are unsure whether a proposed change complies with safety or the HVNL, seek advice from your internal engineering or access team before submitting.

If the Update Network function or edit mode does not appear to work as expected, contact the NHVR using your usual support channels.
