8.1.37. For regulating the movement of which vehicles is this traffic light used?
UAДля регулювання руху яких транспортних засобів застосовується даний світлофор?
This exam question from the Traffic Rules of Ukraine tests the understanding of special traffic lights and how they regulate the movement of rail vehicles. Such signals are important for road safety at intersections and sections with multi-lane traffic, where the tram driver needs to receive a clear command right at the tracks, without relying on a distant “regular” traffic light.
In terms of content, it belongs to the section of the traffic rules about traffic lights, specifically to clause 8.7.5 of the Traffic Rules of Ukraine. This clause describes a T-shaped traffic light with four white-moon signals, which is used specifically to regulate tram movement: permission to proceed is given only when the lower signal and one or more upper signals indicating the permitted direction are lit simultaneously.
By comparison, route vehicles and trolleybuses are usually governed by general traffic lights (or special lane/route signals if provided), but the T-shaped white-moon traffic light is not intended for them. For the theoretical exam, it is also important to remember the practical rule from clause 8.7.5: when the tram traffic light is off or malfunctioning, the tram driver is guided by the usual red, yellow, and green signals.
Clause 8.7.5
To regulate the movement of trams, traffic lights with four white lunar-colored signals arranged in the shape of the letter "T" may be used. Movement is permitted only when the lower signal and one or more of the upper signals are simultaneously on, where the left one allows movement to the left, the middle one — straight ahead, and the right one — to the right. If only the three upper signals are on, movement is prohibited. In case of deactivation or malfunction of tram traffic lights, tram drivers must follow the requirements of traffic lights with red, yellow, and green light signals.
This clause directly states that the T-shaped traffic light with white lunar signals is used specifically to regulate the movement of trams (and is installed for their drivers).
Therefore, the correct answer is "Trams," given that, according to the definition in the Traffic Rules, a traffic light with four white lunar signals in the shape of the letter "T" is intended to regulate the movement of trams.
At intersections or sections where tram tracks run separately from the main traffic lanes, it is important for the tram driver to receive signals directly near the tracks. For this purpose, the Traffic Rules provide a separate type of traffic light, which is easily recognized by its white lunar signals arranged in the shape of the letter 'T'.
According to clause 8.7.5 of the Traffic Rules of Ukraine, such a traffic light is used specifically to regulate tram movement. Its signals give the tram a specific permission and direction of movement: movement is allowed only when the lower signal and one or more upper signals are lit simultaneously. At the same time, the upper signals indicate the direction in which the tram is allowed to move (left, straight, or right). If only the upper signals are on without the lower one, this means movement is prohibited.
For other vehicles (cars, trucks, buses), such a 'T-shaped' traffic light is not intended, as it is installed and oriented specifically for the tram driver near the tram tracks. If this special traffic light is not working or is turned off, the tram follows the regular traffic lights with red, yellow, and green signals.
Therefore, the correct answer is "Trams," since the 'T-shaped' traffic light with white lunar signals, according to clause 8.7.5 of the Traffic Rules, is intended specifically for regulating tram movement and gives them permission and direction of movement.
