This warning sign is used as an early planning cue, not as a last-second prompt. On Swiss roads it appears before the relevant hazard so the driver can adjust speed, following distance, lane position, and observation before the situation becomes demanding. In theory training, the expected answer should connect the sign with a concrete behaviour change: anticipate the hazard, keep control, and avoid overtaking or sudden manoeuvres where the warning reduces the safety margin. Official catalogue code: 1.05.
