Explanation

Correct answer: No

No. The photo shows the D-40 sign 'residential zone', where a pedestrian may use the full width of the road and has priority over vehicles. The horn may be used only to warn of an immediate danger (art. 29), not to hurry along pedestrians who have priority in a residential zone.
