16.1.15. What is the order of precedence for vehicles at this intersection?
UAЯка черговість проїзду автомобілів на даному перехресті?
This is an exam question from the Traffic Rules of Ukraine about the safe passage of intersections and the correct determination of right of way when both directions are simultaneously permitted to move. Such situations are typical in urban traffic and often lead to accidents due to mistakes during left turns, so the topic is directly related to safety and the practical application of traffic rules.
The question tests the section of the Traffic Rules regarding passing intersections, in particular the rules for movement at a controlled intersection (paragraph 16.1). If movement is regulated by traffic signals, the intersection is considered controlled and drivers must follow the signals, not the priority signs. Next, paragraph 16.6 applies: when turning left on a green signal, the driver must yield to oncoming vehicles moving straight or turning right. In the context of the theoretical exam, this checks the ability to see whether trajectories intersect and who has the right of way in such cases.
The option where the car turning left goes first is incorrect: even with a green signal, it does not have priority over the oncoming vehicle moving straight, because the left turn creates a conflict of trajectories and requires yielding. The correct order corresponds to paragraph 16.6 of the Traffic Rules of Ukraine: first, the oncoming vehicle moving straight passes, and only after that does the car turning left safely complete the maneuver.
Clause 16.1
"An intersection where the order of passage is determined by traffic light signals or a traffic controller is considered regulated. At such an intersection, priority signs do not apply. If the traffic light is off or operating in flashing yellow mode and there is no traffic controller, the intersection is considered unregulated, and drivers must follow the rules for unregulated intersections and the relevant road signs installed at the intersection."
This clause in the question checks that the intersection is regulated (movement is permitted by the traffic light signal), and therefore the order is determined by the rules for regulated intersections, not by priority signs.
Clause 16.6
"When turning left or making a U-turn at a green signal of the main traffic light, the driver of a non-rail vehicle must yield to a tram moving in the same direction, as well as to vehicles moving straight from the opposite direction or turning right. This rule must also be followed by tram drivers among themselves."
This clause in the question checks the rule of priority at a regulated intersection: the vehicle making a left turn (white) must yield to the oncoming vehicle moving straight (purple).
Clause 1.10 (terms "Priority", "Yield")
"Priority — the right to move first in relation to other road users."
"Yield — the requirement for a road user not to continue or resume movement, not to perform any maneuvers (except for the requirement to vacate the occupied lane), if this may force other road users who have priority to change direction or speed."
These definitions clarify that "yield" specifically means the obligation not to create an obstacle/not to force the one who has priority to change speed or direction.
Thus, the correct answer is "Purple, white.", given that at a regulated intersection (clause 16.1), when movement is simultaneously permitted, the driver turning left must yield to the oncoming vehicle moving straight (clause 16.6, terms of clause 1.10).
In front of us is a signal-controlled intersection, that is, one where the order of movement is determined by traffic light signals. This means that drivers primarily follow the permissive or prohibitive signal, not the priority signs (paragraph 16.1 of the Traffic Rules).
In this situation, both vehicles have a green signal, so both the purple car going straight and the white car turning left are allowed to proceed. Now it is necessary to determine which of them has the right of way specifically when passing through the intersection.
When a driver turns left at a green signal of the main traffic light, they must yield to oncoming vehicles that are moving straight (paragraph 16.6 of the Traffic Rules). In our case, the white car is turning left, and the purple car is moving straight in the opposite direction, so their paths cross, and the white car must yield to the purple car so as not to force it to change speed or direction.
Therefore, the correct answer is "Purple, white.", since at a signal-controlled intersection both are allowed to move on the green signal, but when turning left, the white car is required to yield to the oncoming purple car going straight (paragraph 16.6, taking into account paragraph 16.1 of the Traffic Rules).
