This exam question focuses on road signs and the safety of maneuvering: correctly recognizing prohibitions helps avoid dangerous situations when changing direction, especially near intersections, breaks in the median strip, and places with limited visibility. In the traffic rules, it is important to distinguish between a U-turn prohibition and a turn prohibition, as these maneuvers have different consequences for the trajectory of movement and the organization of traffic flow.

The question tests knowledge of Section 33 of the Traffic Rules of Ukraine "Road Signs," in particular group 3 "Prohibitory Signs" and sign 3.24 "U-turn Prohibited." This sign directly establishes a prohibition on making a U-turn from the place where it is installed, which is a typical topic for the theoretical exam: the student must recognize the sign by the U-turn pictogram crossed by a diagonal stripe and understand the legal meaning of the prohibition.

Among the answer options, the correct one is the one depicting sign 3.24: it prohibits only the U-turn, not other actions. Other signs in similar tasks usually restrict other maneuvers (for example, turning left or moving in a certain direction) or do not contain a direct indication of a U-turn, so they cannot be the correct answer. In practice, this means: even if making a U-turn seems safe, in the presence of this prohibitory sign, you must continue driving and change direction at a permitted place in accordance with the Traffic Rules of Ukraine.
