When a user is routed through an unnamed segment (other than a parking lot segment), Waze will automatically use the name of the next named segment on the route (a.k.a. road name inheritance). This is useful for getting instructions for ramps and turn lanes. However, this can be confusing in other areas, like large parking lots without road names.
Be sure to understand how unnamed segments operate during navigation before adding names to unnamed segments already on the map.
When Waze gives navigation instructions to "turn", "exit", or "keep" onto an unnamed segment, it will look for a name it can use. If there is a named segment further along your route, it will use (inherit) that name in the instruction. Named segments connected to the unnamed segment which are not part of your provided route, are not relevant.
The inherited name is only used in the displayed and spoken instruction prompts, it does not affect the actual name of the segment.
This always works for Freeways and Ramps .
This never works for Parking Lot Roads .
As of October 2018[update], on all other road types (any road type which is not a Freeway, Ramp, or Parking Lot), this feature only works if:
- The combined length of the consecutive unnamed segments is shorter than 400 meters (1,312 feet),
AND - There are 3 or fewer unnamed segments in a row.
To explain the above conditions from another perspective:
If the consecutive unnamed segments measured together are longer than 400 m (1,312 ft), or if there are 4 or more unnamed segments in a row, Waze will not show or speak a name in the instructions.
