Viewing turn by turn instructions – How to display detailed turn by turn instructions and infrastructure information for a route
What this guide does
This guide explains how to display turn by turn instructions for a route in the National Network Map (NNM) Route Planner. This guide shows how to access the list of instructions, including distances for each segment. This guide also explains how infrastructure and conditions are displayed in the instruction’s drawer.
Prerequisites
A web browser with internet access.
Access to the National Network Map and the Routes tab.
A saved or active route with at least two waypoints.
Date of last review
Date of last review: [25 02 2026]
Step-by-step instructions
Open the National Network Map and go to the Routes tab for your chosen Class 2 vehicle.
Open an existing route or complete your waypoint setup so the route line and summary are visible on the map.
Locate the Directions option associated with the current route.
Click Directions to open the turn-by-turn instructions drawer.
5. Review the list of instructions. For each step you will see:
a) The driving instruction (for example turn, continue, exit).
b) The distance to travel for that segment.
Look for any infrastructure information (for example structures or clearances) that appears in the instructions. Infrastructure on the route is also noted in this list.
Check the route on the map; the route line clearly shows any conditions or restrictions, which are also reflected in the instruction’s drawer.
Tips and common issues
Use the turn-by-turn instructions to brief drivers or confirm that a proposed route is practical before permit applications.
If instructions do not appear, ensure the route has been fully calculated and that you have clicked Directions for the correct route.
Where infrastructure is critical (for example low bridges), cross-check the map and instructions together before relying on the route.
Where to get help
Discuss route instructions with your internal logistics or safety team for complex or unusual routes.
Contact the NHVR Route Planner support team if infrastructure or conditions do not appear correctly in the instructions.
