Lanes
Details on Lanes and how to map them can be found on the Lanes Wazeopedia page. Editors should consider using the Lane Tools script to assist in mapping lanes correctly.
In California, Lanes should be mapped for major intersections where it deviates from what is expected. In other words, do not map if you can turn right from the right lane only and/or you can turn left from the left lane only.
Intersections where you should map Lanes:
- There are multiple left or right turn lanes
- In a # or H junction where there is a U-Turn. The addition of lanes combined with lane heuristics enables Waze to announce a
U-Turn, rather than aTurn Left, Turn Left.

Compound guidance
There are a few situations where compound guidance is needed. Compound guidance is needed at intersections where users should be guided to the proper lane in preparation for the next maneuver.
As an example, consider a driver going from
Look forward/backward the distance for Lane Guidance announcement (about ½ mile for MH and ¼ mile for mH and lower) if the intersection loses lanes. The reason is that this could cause a driver to get into the wrong lane too early. Example, Mission entrance to I-680.
Adjust/remove AGCs as needed.
Compound instructions
Place a MC over these areas.
