Steep descent
Warning signsSign no. 1.10OSR art. 8
What the sign says
A marked downhill gradient, its percentage shown on the sign. Go down in the gear you would climb in, so the engine holds the car back.
The exam trap
Continuous braking heats the brakes until they fade. Going downhill, the vehicle coming up has priority where passing is impossible.

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.
