The vertical warning sign shown in the image indicates the proximity of a road section with low verges. This sign warns the driver that the side verge is at a lower level than the carriageway, which requires special attention and care when driving to prevent the wheels from leaving the pavement.The other options are incorrect because the falling rocks sign shows a mountain with falling stones, and the road obstruction sign shows a graphic representation of an obstacle or a stopped vehicle on the carriageway, which does not correspond to the illustrated symbol.
