What the sign says
The general limit outside built-up areas. It applies from the end of the built-up area, with no disc required.

It is also the limit for cars towing a trailer, motorway included — the trailer does not follow the section limit.

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.
