What the sign says

The same warning as its mirror image, but on the left: the road narrows there, or an obstacle encroaches on that edge.

The exam trap

The loss of a lane where several run in the same direction is not announced by this triangle but by the lane-layout panel.

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.
