UAНа даний сигнал регулювальника рух дозволено:
This exam question from the Traffic Rules of Ukraine tests the ability to safely pass through intersections where traffic is controlled not by traffic lights or signs, but by a traffic controller. Such situations often occur during traffic jams, road repairs, or accidents, and a correct understanding of the controller's gestures directly affects safety and helps avoid conflicts at intersections during the theoretical exam.
The question belongs to the section of the Traffic Rules concerning traffic regulation and the signals of the traffic controller (points 8.1 and 8.8 b)). For the signal "right arm extended forward," a clear rule applies: from the back and the right side of the controller, movement is prohibited; from the left side, non-rail vehicles are allowed to move in all directions; from the front (chest), movement is allowed only to the right. That is why, in the situation shown in the diagram, two cars have the right of way: one approaches from the left side of the controller and may continue driving, the other is facing the controller's chest and is allowed to make only a right turn.
The analysis of the answer options comes down to checking who is standing in the permitted sectors. The option with three cars is incorrect because it adds a vehicle from a prohibited side (right side or back). The wording about "the black and green" is also incorrect for the same reason: in this configuration, the black car is in a prohibited direction. The answer where only one car is allowed is incomplete, because with this gesture of the controller, there are always two permitted approaches (to the left of the controller and "to the chest" with the restriction of a right turn), so movement is allowed not for one, but for two participants.
Clause 8.1
Traffic regulation is carried out using road signs, road markings, road equipment, traffic lights, and traffic controllers. The signals of the traffic controller take precedence over traffic light signals, the requirements of road signs, and road markings.
Brief application: in the presence of a traffic controller, drivers must follow his signals (even if other means of traffic organization indicate otherwise).
Clause 8.8 b)
The signals of the traffic controller are the position of his body, as well as hand gestures, including with a baton or a disc with a red reflector, which are used with the following meanings:
b) right arm extended forward:
• from the left side — trams are allowed to turn left, non-rail vehicles are allowed to move in all directions; pedestrians are allowed to cross the carriageway behind the controller;
• from the chest side — all vehicles are allowed to move only to the right;
• from the right side and from the back — movement of all vehicles is prohibited; pedestrians are allowed to cross the carriageway behind the controller.
Brief application: with this position of the controller, non-rail vehicles located to his left may move in all directions, and those in front of the controller's chest — only to the right; from the back and right side, movement is prohibited.
That is, the correct answer is "The yellow and green cars.", 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, and on the chest side — only to the right, while from the back and right side — movement is prohibited.
At the intersection, traffic is controlled by the traffic controller, so we do not follow the general rules for passing intersections of roads of equal importance, but rather his specific signal. The scenario shows the signal: the controller's right arm is extended forward. The meaning of this signal is defined in clause 8.8 (b) of the Traffic Rules of Ukraine.
First, it is convenient to immediately eliminate the prohibited directions. According to this signal, vehicle movement is prohibited from the back of the controller, as well as from his right side. That is, vehicles approaching the controller from these two sides must stop, regardless of whether they intend to go straight or turn.
Next, let's consider the permitted directions. If a vehicle is on the left side of the controller, non-rail vehicles are allowed to move in all directions. This means that the yellow car, which approached from the left side, can continue moving (specifically straight ahead, as shown in the situation).
If a vehicle is on the chest side of the controller, according to clause 8.8 (b), all vehicles are only allowed to turn right. Therefore, the green car, which approached the controller "facing his chest," is only allowed to turn right, while going straight or left is prohibited for it.
Thus, in this situation, only two cars have the right to move: the yellow one (from the left side of the controller) and the green one (from the chest side, but only to the right). Therefore, the correct answer is "To the yellow and green cars," since with the signal "right arm extended forward," movement is allowed from the left side in all directions, and from the chest side only to the right, while from the back and right side movement is prohibited.
