Double bend, first to the left
Warning signsSign no. 1.04OSR art. 4
What the sign says
Two linked bends, the first to the left. The sign covers the whole sequence: set your speed once, before the first one.
The exam trap
Where more than two bends follow one another, a supplementary plate gives the length of the winding stretch: the sign is not repeated at every curve.

Overtaking and passing
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.
