European route number plate
Information signsSign no. 4.56OSR art. 56
What the sign says
A white E and number on green: the stretch belongs to the European through-route network.
The exam trap
The European number is layered on the Swiss one rather than replacing it: the same motorway often carries both plates side by side.

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.
