Information signsSign no. 4.70OSR art. 89a
What the sign says
The plate marks an emergency call point and the direction to reach it along the road.
The exam trap
The call point has one advantage over a mobile: it locates the caller exactly, without their having to say where they are.

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.
