Regulatory signsSign no. 2.41OSR art. 24

Closing off a right turn with a blue order has the same effect as a red ban — but a blue order is carried out, not worked around.

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.
