10.67. Are you permitted to turn left in this situation?
UAЧи дозволено Вам повернути ліворуч у даному випадку?
This exam question from the Traffic Rules of Ukraine tests the driver's attention to road signs and the safe choice of maneuver at an intersection. Such situations are directly related to the prevention of head-on collisions and are typical for the theoretical exam, since an error in the direction of movement on a one-way street quickly turns into a gross violation of traffic rules.
The question belongs to the topic of passing uncontrolled intersections and complying with road signs (section 33 "Road Signs," as well as regulations regarding one-way traffic). The key here is sign 5.7.1 "Exit onto a one-way road," which allows movement only in the direction indicated by the arrow; according to the requirements of the Traffic Rules, the driver is obliged to follow the instructions of the signs, and movement against the general flow on a one-way road is prohibited. Additionally, at an unequal intersection, one must take into account the priority and the requirement to "give way" to vehicles on the main road, regardless of their further direction.
If you choose the option that allows the maneuver, it ignores the essence of sign 5.7.1: turning in a direction that would put you against the established direction of one-way traffic is an incorrect trajectory and violates the rules. That is why the correct answer in this exam question is the option that reflects the prohibition of such a maneuver: the driver does not have the right to enter a one-way road in such a way as to move against the flow.
Clause 33.5.7.1 — 33 "Road Signs", 5 "Informational and Directional Signs", sign 5.7.1 "Exit onto a One-Way Road"
Sign 5.7.1 informs that the road being entered has one-way traffic; movement is allowed only in the direction indicated by the arrow on the sign.
Clause 11.5
On roads with one-way traffic, it is prohibited for vehicles to move against the general flow of traffic.
Clause 8.4
Road signs establish a certain order of movement; road users are required to comply with the requirements of road signs.
Clause 1.10 (term "One-way road")
One-way road — a road on which vehicle movement across the entire width of the carriageway is carried out in one direction.
Clause 33.2.1 — 33 "Road Signs", 2 "Priority Signs", sign 2.1 "Yield"
Sign 2.1 requires yielding to vehicles moving on the main road (the road being crossed by the driver), and not to proceed if this could force them to change direction or speed.
Clause 16.11
At an intersection of roads with different priorities, the driver of a vehicle moving on a secondary road must yield to vehicles approaching on the main road, regardless of their further direction of movement.
Thus, the correct answer is "Prohibited.", given that according to the definition in the Traffic Rules, sign 5.7.1 allows movement on a one-way road only in the direction of the arrow, and turning left in this situation would mean entering and moving against the established direction (which is prohibited).
You are facing an uncontrolled intersection where the order of passage is determined by road signs. It is especially important to note that the intersecting road has one-way traffic, and this must be taken into account before choosing your turning trajectory.
Sign 5.7.1 "Entry onto a one-way road" indicates that after entering the intersecting road, movement is allowed only in the direction shown by the arrow. That is, you may enter this road only in such a way that you immediately move in the indicated direction.
If you make a left turn in this situation, you will end up on a one-way road and will be forced to move against the permitted direction, that is, against the flow of traffic. This contradicts the requirements of sign 5.7.1, as it directly sets the only permitted direction of movement on this road.
Therefore, the correct answer is "Prohibited," since sign 5.7.1 allows movement on the intersecting road only in the direction of the arrow, and a left turn would lead to movement against the one-way flow.
