This tag can be used to show that a way is not a (physical) highway.
In almost all circumstances, this tag is not needed and should be omitted; the absence of a highway=* tag on an object will be sufficient for this purpose.
However, occasionally, there may be ways that one would expect to be highways, but are not. In this case, highway=no can be added to explicitly indicated to other mappers and data users that there is no highway here. This allows us to distinguish between the case of a highway type being unknown and needing to be determined, and the case of the way being known not to be a highway.
For example, in the UK, there are sometimes legal Rights of Way that are inaccessible, resulting in a legal highway that is not physically present or usable on the ground. Due to administrative errors, unauthorised constructions or lack of maintenance, the official line of a legal route may pass through dense woodland, though walls of a building a building or though a lake. highway=no can be used in these cases to explicitly mark the way as not being a highway, while still recording the official line.
