One-way street with contraflow cycling
Information signsSign no. 4.08.1OSR art. 46
What the sign says
The street is one-way for vehicles, but a symbol names the class allowed to ride against the flow — here, cyclists.
The exam trap
One-way no longer guarantees that nobody comes towards you. The risk concentrates on pulling out of parking spaces and in tight bends.

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.
