Road narrows on the right
Warning signsSign no. 1.08OSR art. 7
What the sign says
The road narrows on one side only, the right, or an obstacle juts dangerously into that edge. Passing becomes difficult.
The exam trap
A one-sided narrowing does not say who goes first. Where needed, the width at the narrowest point appears on a supplementary plate.
Study topic
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.
