Question

DentroTest · Accepted Answer

The sign shown is P-33, whose official name is “Reduced visibility”. This warning sign alerts drivers to the proximity of a section where traffic is considerably hindered by a significant loss of visibility, frequently caused by weather phenomena such as fog, smoke, heavy rain or snow. The other options represent different signs: the danger of falling rocks is signaled by P-26, and the presence of loose gravel is identified by sign P-28.
