End of the general 50 km/h limit
Regulatory signsSign no. 2.53.1OSR art. 22 · art. 32
What the sign says
The barred disc ends the general 50 km/h regime. Beyond it, the general limit outside built-up areas — 80 km/h — applies.
The exam trap
It stands from the point where neither side of the road is compactly built up any more. On minor secondary roads, neither sign is needed at all.

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.
