What does this traffic sign warn us of?

Question

DentroTest · Accepted Answer

The sign shown is P-21a ("Children"), a triangular warning sign with a red border and a white background. Its regulatory meaning warns of danger due to the proximity of a place frequented by children, such as a school or a playground. On seeing it, the driver must slow down and take extreme care to avoid running over children, given their possible unpredictable behavior. Entry into a stay and play zone, with priority for pedestrians, is indicated by the square sign S-28, not by this one. And the approach to a pedestrian crossing is warned of by sign P-20a or indicated on the spot by sign S-13.
