No overtaking by lorries
Regulatory signsSign no. 2.45OSR art. 26
What the sign says
Only lorries and heavy work vehicles are covered: they may not overtake multi-track vehicles that are moving.
The exam trap
A private car is not concerned and may overtake as usual. The ban lifts only at the end-of-ban-for-lorries sign.

Overtaking and passing
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.
