This guide explains how to add conditions or restrictions to road segments using the standard conditions library in a Network Update Request. It describes when to use a condition versus a restriction and how to search, configure and save condition or restriction text. It also highlights how these tools support compliance with the Heavy Vehicle National Law (HVNL).

1. Open the relevant network and create or open a Network Update Request so the network is in Edit mode.

2. Use a Network Management tool (Pan and Select, Area tool, Route Selection tool, or All in My Area of Responsibility) to select the segment or group of segments that need a condition or restriction.

3. Right-click on the selected segment(s) and choose the option to Add condition. This opens the standard conditions library.

4. In the conditions library, use the search field to narrow down the condition you need. The list has been streamlined to reduce duplication and make it easier to find the right condition.

5. Select the appropriate standard condition. For some conditions, enter specific parameters (for example time-of-day or speed-related details) as prompted.

6. Review the proposed condition text shown in the lower panel. If required, edit the text to make it accurate for the road segment while remaining compliant with the Heavy Vehicle Law.

7. Click Add Condition to apply the condition to the selected segment(s) within the Network Update Request. This step records the condition as part of the request but does not yet change the published network.

8. To add more than one condition, repeat Steps 3–7 for the same segment(s), using new search terms to find additional standard conditions.
​

9. If there is no access allowed for a road for a particular vehicle, use a Restriction instead of a condition. Right-click the segment(s), choose the restriction option and follow the same process using the restriction library.

10. If none of the standard entries match your needs, use the free text condition option and draft wording that complies with your jurisdiction’s requirements and the HVNL.

Use a condition when operators are allowed to use the road but must follow specific requirements (for example time windows or speed limits). Use a restriction when access for that vehicle is not permitted.

The standard conditions library has been reviewed so that wording is consistent and compliant with the Heavy Vehicle Law; prefer standard entries over free text where possible.

Remember that Add Condition/Add Restriction applies the condition or restriction only within the Network Update Request; no change is applied to the live map until the request is submitted, approved by the Access Policy team and published.

If you need to adjust a condition after saving, right-click the segment and choose the view/edit option to update the text or add further conditions.

Check your organisation’s internal policies for standard condition wording and when restrictions should be applied.

Contact the NHVR Access Policy or Network Management support team if you are unsure which standard condition or restriction to choose.
