No parking
Regulatory signsSign no. 2.50OSR art. 30
What the sign says
A single red bar: parking is forbidden, stopping is still allowed. A stop is for letting people in or out or loading, without leaving the vehicle.
The exam trap
The difference is the number of bars: one bar forbids parking, two crossed bars forbid stopping as well.

Parking and stopping
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.
