No vehicles with water-polluting loads

Regulatory signsSign no. 2.11OSR art. 19

What the sign says

The stretch is closed to vehicles whose load could pollute groundwater or a watercourse if it leaked or in a crash.

The exam trap

Where the ban is absent, the water-protection-zone sign asks only for extra care: one closes the road, the other does not.

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.
