Correct answer
C. Frosted road or black ice, even if they do not occur on other sections of the road.
Explanation
In the photo, before the entrance to a bridge, there is sign A-32 "frost on the roadway" - a yellow triangle with a snowflake symbol. When driving onto a bridge marked with this sign, you can expect frost on the roadway or black ice, even if they do not occur on other sections of the road - answer C. The sign does not warn about snowdrifts (A) or snowfall (B).
The Regulation on road signs and signals states that sign A-32 warns of frost on the roadway or black ice that may occur on the road. Bridges and flyovers are cooled by the air from below, so their surface freezes faster than a roadway lying on the ground - at a temperature close to zero there may be ice on the bridge, even though the asphalt before it was only wet. The Road Traffic Act requires you to adjust your speed to the weather conditions and the state of the road, so before such a sign you slow down, you do not brake or turn sharply on the bridge itself, and you increase the distance from the vehicle in front.
