Is it necessary to exercise special caution in the presented situation?

In the video you are driving along a street in a town and approaching a pedestrian crossing in front of a school; on the right there is sign D-6 "pedestrian crossing" with plate T-27 showing the silhouette of a child, and the pavement near the crossing is fenced off with red and white barriers. Particular caution is required here. The answer is: yes.

The Road Traffic Act requires a driver approaching a pedestrian crossing to exercise particular caution, to reduce speed so as not to endanger a pedestrian who is on the crossing or stepping onto it, and to give way to a pedestrian who is on the crossing or stepping onto it. The Regulation on road signs and signals states that plate T-27 under sign D-6 indicates a crossing used especially often by children, and a driver approaching a place marked with sign D-6 must reduce speed. Children are the least predictable pedestrians: they are short, so they are easy to miss behind a parked car, and they run onto the roadway without looking when they see a friend on the other side. Before such a crossing you slow down more than before an ordinary one, move your foot from the accelerator to above the brake, and watch not only the crossing but also the pavements on both sides, especially at the times when lessons start and finish.
