This exam question from the Traffic Rules of Ukraine tests the ability to safely pass intersections where traffic is regulated not by traffic lights or priority signs, but by the signals of a traffic controller. Such situations are especially dangerous at complex or equivalent intersections, as the driver must quickly determine from which directions movement is permitted and from which it is completely prohibited, in order to avoid trajectory conflicts and accidents.
The question relates to Section 8 "Traffic Regulation," topic "traffic controller signals" (clause 8.8 b) of the Traffic Rules of Ukraine) and typically appears on the theoretical exam. When the signal is "right arm extended forward," non-rail vehicles on the left side of the controller are allowed to move in all directions, from the chest side — only to the right, and from the right side and the back — movement is prohibited. Therefore, only the vehicle located on the left side of the controller may proceed (in the diagram, this corresponds to the yellow car).
Analysis of the answer options comes down to correctly identifying the sides of the controller: the option with the yellow car is correct because it is positioned on the "left side," where there are no direction restrictions for non-rail vehicles. Options that include the black or red car are incorrect, since movement is prohibited from the back and right side regardless of the intended maneuver. Options that add the white car are also incorrect: for the "chest" side, only a right turn is permitted, so for any other intention, it must stop and wait for the next signal, which makes such answers incorrect in the format of this exam question.
Clause 8.8 b) (Section 8 "Traffic Regulation", traffic controller's signals)
"Right arm extended forward: trams are allowed to move from the left side of the controller — to the left; non-rail vehicles are allowed to move from the left side of the controller — in all directions, from the chest side — only to the right; from the right side and from the back side, movement of all vehicles is prohibited."
Brief application to the situation: with this signal, movement is prohibited "from the back side" and "from the right side" of the controller; "from the chest side" — only to the right; "from the left side" — non-rail vehicles in all directions. Therefore, only the vehicle that is on the left side of the controller (in the task — the yellow car) may proceed.
Clause 8.9 (Section 8 "Traffic Regulation", priority of the controller's signals)
"The signals of the traffic controller are mandatory for all road users and take precedence over traffic light signals, road signs, and road markings."
That is, the correct answer is "To the yellow car.", given that according to the definition of the Traffic Rules, when the controller's signal is "right arm extended forward", non-rail vehicles on the left side of the controller are allowed to move in all directions, while from the chest side — only to the right, and from the back and right sides — movement is prohibited.
There are no traffic lights or priority signs at the intersection, so the order of movement is determined only by the traffic controller. In such situations, you must follow the signals of the controller, as they take precedence over the general rules for driving through intersections of equal roads.
According to clause 8.8 (b) of the Traffic Rules of Ukraine, when the controller's right arm is extended forward, the following principle applies to non-rail vehicles: movement is always prohibited from the back side of the controller, as well as from the side of the extended right arm (as it effectively “blocks” that direction). Therefore, vehicles located on these two sides are not allowed to start moving, regardless of where they intend to go.
For the other two directions, the rules are different. From the left side of the controller, non-rail vehicles are allowed to move in all directions (provided safety and maneuvering rules are observed). The yellow car is in this position relative to the controller, so it has the right to continue moving.
The white car, which is facing the controller's chest, has a restriction for this signal: it is only allowed to turn right. If its intended direction is different, it must remain in place and wait for another signal, because moving straight or left from this position is prohibited.
Therefore, the correct answer is "The yellow car," because according to the controller's signal with the right arm extended forward (clause 8.8 (b) of the Traffic Rules), movement from the left side of the controller is allowed in all directions, while for other cars in this situation, movement is either prohibited or allowed only with restrictions.
