Unsigned exit numbers
In California, highway forks and ramps sometimes lack exit number signage. Unsigned information generally does not belong in Waze instructions, but Caltrans has committed to marking exit numbers throughout California over time.
In simple situations where there is little chance of driver confusion, editors may add documented but unsigned exit numbers in expectation of their eventually appearing on signage. In complex situations, however — for example, when a highway comes to an end, changes designation, or joins a shared alignment — adding unsigned exit numbers to Waze instructions could confuse drivers. In such cases it is better to omit exit numbers until they become signed.
Editors may have added unsigned exit numbers even in complex, potentially confusing situations. These should not be removed without careful review, preferably based on personal experience and/or driver reports. There is no campaign to remove unsigned exit numbers from the Waze map of California.
