No motorcycles
Regulatory signsSign no. 2.04OSR art. 19
What the sign says
The ban covers all motorcycles. It often stands where noise is the reason: mountain roads, residential districts, leisure routes.
The exam trap
Partial bans combine on one disc: two or three stacked symbols form a single sign, to be read in full before you conclude.

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.
