Hard shoulder running
Information signsSign no. 4.77.2OSR art. 59
What the sign says
The panel says the hard shoulder may be used: it temporarily becomes an ordinary running lane.
The exam trap
Without that express authorisation, the hard shoulder may be used only in case of absolute necessity — never to gain a place in a jam.
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.
