What the sign says
The driver must carry straight on or turn right. Turning left is ruled out.
The exam trap
These signs are read when you pick your lane, not when you turn: once you are in the wrong one, it is too late to correct.

Signs and road markings
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.
