Steep ascent

Warning signsSign no. 1.11OSR art. 8 · OCR art. 38

What the sign says

A marked climb, its gradient shown on the sign. Change down before you lose momentum, not once the engine is already labouring.

The exam trap

Meeting head-on on a slope works against intuition: the vehicle heading down reverses, unless the one climbing is near a passing place.

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.
