8.1.63. Which of the traffic lights is used to regulate the movement of vehicles on streets, roads, or carriageway lanes where the direction of traffic can be reversed?
UAЯкий зі світлофорів застосовується для регулювання руху транспортних засобів на вулицях, дорогах або смугах проїзної частини, напрямок руху на яких може змінюватися на протилежний?
This exam question from the Traffic Rules of Ukraine concerns road safety in areas where traffic organization changes depending on the time of day or congestion. Most often, this refers to lanes that during peak hours may operate in one direction, and at other times — in the opposite direction, so it is important for the driver to quickly and correctly interpret the signals that control movement specifically on the lane, and not the entire intersection.
The question tests knowledge of the section of the Traffic Rules about traffic lights, specifically point 8.7.4, which describes reversible regulation. The theoretical exam often includes recognizing reversible traffic lights: their key signals are a red X, which prohibits movement on the lane above which it is located, and a green downward arrow, which allows movement on this lane. There may also be a yellow diagonal arrow down to the right, which warns of a mode change and requires you to change lanes to the right in advance; when the signals are off, entry to the reversible lane is prohibited.
Among the options provided, the correct one is the traffic light that has the features of reversible lane control (red X and/or green downward arrow) — this is traffic light 1. The other images correspond to other types of regulation: a traffic light for railway crossings, a traffic light for enterprise territories or places where the carriageway narrows, as well as direction traffic lights that are not intended for lanes with the possibility of changing the direction of movement to the opposite. Understanding this difference helps to avoid entering a lane with oncoming traffic and is a typical knowledge check in the traffic rules exam.
Clause 8.7.4
To regulate the movement of vehicles on streets, roads, or on lanes of the carriageway where the direction of movement can be changed to the opposite, reversible traffic lights with a red X-shaped signal and a green signal in the form of a downward arrow are used. These signals prohibit or allow movement on the lane above which they are located. The main signals of the reversible traffic light may be supplemented by a yellow signal in the form of an arrow slanting diagonally down to the right, the activation of which prohibits movement on the lane marked on both sides by road marking 1.9, and informs about the change of the reversible traffic light signal and the need to change to the lane on the right. When the signals of the reversible traffic light located above the lane marked on both sides by road marking 1.9 are off, entry to this lane is prohibited.
That is, the correct answer is "Traffic light 1.", given that according to the definition of the Traffic Rules, for lanes/roads where the direction of movement can be changed to the opposite, a reversible traffic light (with a red X-shaped signal and a green downward arrow) is used.
On certain roads or on specific lanes, the direction of traffic may change depending on the time of day or traffic load. Such lanes are called reversible lanes, and drivers need to clearly understand when it is allowed to drive on them and when entry is prohibited.
According to clause 8.7.4 of the Traffic Rules of Ukraine, reversible traffic lights are used to control traffic on streets, roads, or lanes where the direction can become opposite. They are easy to recognize by their signals: a red X prohibits movement on the lane above which it is located, while a green downward arrow allows movement on that lane. Sometimes a yellow diagonal arrow pointing down to the right is added, warning that movement on the lane will soon be prohibited and requiring drivers to move to the right. An important detail: if the reversible traffic light above the lane is turned off, entry to such a lane is also prohibited.
Among the proposed options, only traffic light 1 has the characteristic features of a reversible traffic light (it controls movement specifically on a lane that can change direction). Other traffic lights are intended for different situations: for railway crossings, for enterprise territories or narrowing areas, or for movement in designated directions, but not for reversible lanes.
Therefore, the correct answer is "Traffic light 1," because it is the reversible traffic light (with a red X and a green downward arrow) that is used to regulate traffic on lanes where the direction can change to the opposite.
