Interchange number plate
Information signsSign no. 4.59.1OSR art. 56
What the sign says
Black symbol and number on white, as for junctions, but for a point where two motorways split or meet.
The exam trap
Junctions and interchanges are not signposted alike: a junction links the motorway to the ordinary network, an interchange links two motorways to each other.
Study topic
Motorway and expressway
The signs are the official depictions by the Federal Roads Office, from the annexes of the Signalling Ordinance (SR 741.21): official works, unprotected under Art. 5 of the Copyright Act. The explanations, by contrast, are written from federal law — never taken from a third-party catalogue.
