Art. 84 Ordinance of 5 September 1979 on Road Signage (OSR) - Principles
Art. 84 OSR · Principles
On motorways and semi-motorways, directional signs feature white inscriptions on a green background; conversely, signs or sections of signs indicating destinations accessible via other roads feature white inscriptions on a blue background.
Distances on directional signs as well as on signals placed before an ancillary facility or a hazardous location are indicated in meters, except on the "Distance Panel in Kilometers" (4.65).
When a short section of a main road is constructed as a semi-motorway, this section will generally be signaled in the manner of a main road (art. 37).
A short section constructed as a semi-motorway between a section of motorway and a section of main road will generally be signaled in the manner of a semi-motorway (art. 45, para. 1). The connection of a motorway or a semi-motorway with a short section of another motorway or semi-motorway will be signaled as a junction (art. 86), and not as a branch (art. 87).
