No skiing
Regulatory signsSign no. 2.15.1OSR art. 19
What the sign says
The sign bans skiing in every form. It closes to skiers a road or crossing that traffic makes dangerous.
The exam trap
It is seasonal: the ordinance requires removing it at the end of the winter season. A sign gone in summer has not been revoked, just put away.

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.
