What the sign says
On motorways and expressways without a hard shoulder, this sign marks the bays for stops forced by circumstances.
The exam trap
Voluntary stopping and parking are forbidden there: it is a breakdown bay, not a rest area. The sign is repeated as an advance sign.

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.
