33.1.53. Which of the depicted road signs warns about a curve with limited visibility?
UAЯкий із зображених дорожніх знаків попереджає про заокруглення з обмеженою оглядовістю?
This is an exam question from the Traffic Rules of Ukraine about warning road signs and traffic safety on sections with increased risk. Limited visibility in a curve (turn) is dangerous because the driver notices an obstacle, oncoming traffic, or a change in driving conditions later, so it is important to reduce speed in advance and be ready to maneuver without sudden actions.
The question tests knowledge of Section 33 “Road Signs,” Group 1 “Warning Signs” of the traffic rules, specifically the meaning of sign 1.2 “Dangerous left turn.” According to the Traffic Rules, this sign is used before a turn with a small radius (less than 500 m outside populated areas and less than 150 m within populated areas) or before a curve with limited visibility, so among the given options, it is the one that matches the content of the theoretical exam.
If we compare the other options: the “Junction with a secondary road” sign warns of the possible appearance of vehicles from the side, but does not describe a curve; “Slippery road” concerns tire grip with the surface, not the geometry of the road; “Road narrowing” informs about a change in the width of the carriageway. Only “Dangerous left turn” directly warns about a turn with potentially insufficient visibility, so in real conditions, this is a signal to choose a safe speed in advance, maintain a steady trajectory, and be attentive to oncoming traffic.
Clause 33.1 — 33 "Road Signs", 1 "Warning Signs"
Warning signs inform drivers about approaching a dangerous section of the road and the nature of the danger.
This provision specifies that signs in this group are used specifically to warn about danger (in particular, about dangerous turns/curves).
Clause 33.1 — 33 "Road Signs", 1 "Warning Signs", sign 1.2 "Dangerous Left Turn"
Dangerous left turn. A road curve with a radius of less than 500 m outside populated areas and less than 150 m — within populated areas, or a curve with limited visibility.
This definition directly contains the feature from the question — "a curve with limited visibility", therefore the correct sign is 1.2 (in the image — No. 4).
That is, the correct answer is "Sign 4.", considering that according to the definition of the Traffic Rules, sign 1.2 "Dangerous left turn" warns, in particular, about a curve with limited visibility.
The question asks you to identify the sign that specifically warns about a curve in the road with limited visibility. The key word here is curve: this refers to a change in the direction of travel, that is, a turn where the driver cannot see far enough ahead on the road.
Let’s consider the proposed signs by their meaning. The sign that indicates the junction with a secondary road warns of possible vehicles entering from the side, but does not describe a turn or curve. The "Slippery road" sign warns about reduced surface grip, but this is a different hazard not related to the geometry of the turn. The "Road narrows" sign indicates a change in the width of the carriageway, but also does not warn about a curve.
According to Section 33 of the Traffic Rules of Ukraine, warning sign 1.2 "Dangerous left turn" is used when there is a small-radius curve ahead or a curve with limited visibility. That is, this sign directly matches the wording of the question: it warns the driver that there is a turn ahead where, due to the road configuration or obstacles, visibility is insufficient, and it is necessary to choose a safe speed in advance and be attentive.
Therefore, the correct answer is "Sign 4," as it corresponds to sign 1.2 of the Traffic Rules of Ukraine and warns about a dangerous curve (turn) with limited visibility.
