What danger does this warning traffic sign warn us of?

Question

DentroTest · Accepted Answer

The sign shown corresponds to warning sign P-19 (“Slippery road”). Like all triangular signs with a red border and white background, its function is to warn in advance of the proximity of a danger so that we can adapt our driving. Specifically, P-19 warns of a section of roadway where tire grip may be seriously compromised because the road surface is slippery (due to moisture, ice, gravel or the asphalt material itself). For moped riders, this warning is critical, since loss of grip on two wheels usually ends in an immediate fall. There is no sign that prohibits zigzagging: prohibitions are circular. And a succession of dangerous curves is warned of by signs P-14a or P-14b, not by this one.
