Status: de facto

The access=no tag indicates that the object is not to be used by the general public, with stronger interdiction than the access=private tag (see explanation). For example, a stretch of roadway may be closed with a "Road Closed" sign and barricades due to a serious damage to a road or a long-term construction project. There may be a physical reason why no one would realistically be able to traverse the road. If applicable, also map any barriers that prevent anyone from entering or traversing the road.

access=no, as any other access=* value may be overridden by more specific access tags. See access=* to see in detail how access restrictions are defined. E.g. a road tagged access=no and psv=yes generally withdraws any legal right of way but permits public service vehicles. A routing program in psv mode may use this way.

Note that difference between access=no and access=private is subtle and may not be applied by many mappers.

Illegal objects

Illegal railway crossing (with "illegal railway crossing, 2 people died here and 2 were injured" sign). Such highway=footway needs access=no to make clear that it should not be used, for example, in typical routing. Railway-path shared node can be marked with crossing=no

This tag is a proper method to mark existing objects such as path as existing but illegal to use. It includes illegal railway crossings, illegal paths through nature reserves etc. Such objects can be mapped but should be tagged as illegal to use by adding access=no.
