10.20. Is the driver allowed to make a U-turn at this location?
UAЧи дозволено водієві виконати розворот у даному місці?
This is an exam question from the Traffic Rules of Ukraine concerning the safe change of direction in areas with potentially hazardous road conditions. Such situations are especially important for the theoretical exam, as a U-turn is performed at low speed and temporarily blocks the roadway, so with insufficient visibility the risk of collision increases sharply.
The question tests knowledge of Section 10 of the Traffic Rules of Ukraine, "Starting to Move and Changing Direction," particularly prohibitions on U-turns. The key condition here is limited visibility: the road may be visible for less than 100 meters in at least one direction due to the road's geometry or obstacles (vegetation, structures, etc.). Warning sign 1.1 "Dangerous Right Turn" directly indicates a small-radius curve and/or limited visibility, and according to clause 10.7 (d) of the Traffic Rules, a U-turn in such conditions is prohibited.
Therefore, the "allowed" option is incorrect: even if the maneuver seems possible, in an area with visibility less than 100 m, other drivers may notice the turning vehicle too late. The correct conclusion for this exam question is that the maneuver is prohibited, and in practice, you should drive further and choose a place where visibility ensures the safe execution of a U-turn in accordance with the traffic rules.
Clause 10.7 (d) (Section 10 "Starting movement and changing its direction")
U-turns are prohibited: (d) if the road visibility is less than 100 m in at least one direction.
Clause 1.10 (term "Limited visibility")
Limited visibility — visibility of the road in the direction of movement, restricted by the geometric parameters of the road, roadside engineering structures, plantings and other objects, as well as vehicles.
Clause 33.1.1 — 33 "Road signs", 1 "Warning signs", sign 1.1 "Dangerous right turn"
Sign 1.1 "Dangerous right turn" — warns about a small-radius right curve or limited visibility.
(Application: on a section marked with sign 1.1, due to the curve and/or limited visibility, a 100 m visibility in at least one direction may not be ensured, therefore a U-turn is prohibited according to clause 10.7 (d).)
Thus, the correct answer is "Prohibited.", considering that according to the definition in the Traffic Rules, a U-turn is prohibited if the road visibility is less than 100 m in at least one direction (clause 10.7 (d)), and sign 1.1 warns about a dangerous curve/limited visibility.
In this situation, the driver is on a section of the road where warning sign 1.1 "Dangerous right turn" is installed. This sign warns that there is a sharp curve ahead or a turn with limited visibility. That is, the driver receives advance information that visibility in the direction of travel may be insufficient.
In the image, the view of the road is partially blocked by greenery, which prevents the driver from confidently seeing whether there are vehicles approaching from the opposite direction or from around the turn. Such a situation is an example of limited visibility, when the road situation cannot be seen over a sufficient distance.
According to clause 10.7 (d) of the Traffic Rules of Ukraine, a U-turn is prohibited if the visibility of the road is less than 100 m in at least one direction. During a U-turn, the vehicle moves slowly and for a certain time blocks the lane, so in poor visibility other drivers may notice the obstacle too late, which creates a real risk of collision.
Therefore, the correct answer is "Prohibited," since in this area, due to limited visibility, the road cannot be seen for at least 100 m, and according to clause 10.7 (d) of the Traffic Rules, a U-turn is not allowed in such a place.
