This exam question from the Traffic Rules of Ukraine tests the ability to correctly interpret combinations of road signs and supplementary plates, which directly affects traffic safety and helps prevent mistakes when choosing a lane. In real-life situations, it is often the plates that specify to whom a prohibition, order, or information applies, so for the theoretical exam, it is important to learn how to determine the area and scope of requirements on the road.
The question belongs to Section 33 of the Traffic Rules of Ukraine, Road Signs, specifically to the supplementary plates to road signs (item 33.7 and plate 7.9 Lane). It checks the understanding that plate 7.9 does not change the meaning of the sign but clarifies to which lane its effect or the effect of the traffic light it is installed with applies, and it is placed directly under the relevant sign.
The analysis of the answer options comes down to the function of this plate: statements about the end or beginning of the sign's area of effect are incorrect, as other plates are provided in the Traffic Rules to indicate the extent or boundaries of effect. Instead, the correct interpretation fully corresponds to the definition of 7.9: it indicates a specific traffic lane (the term Traffic Lane is defined in item 1.10), and it is the drivers in this lane who must comply with the requirement of the sign or traffic light signal, while adjacent lanes may not be subject to this effect without separate indication.
Clause 33.7 (33 "Road Signs", 7 "Plates to Road Signs")
Plates clarify or limit the effect of road signs with which they are used. Plates are placed directly under the signs with which they are used.
Clause 33.7.9 (33 "Road Signs", 7 "Plates to Road Signs", plate 7.9 "Traffic Lane")
Plate 7.9 "Traffic Lane" determines the lane to which the sign or traffic light, with which it is installed, applies.
Clause 1.10 (term "Traffic Lane")
Traffic lane — a longitudinal strip on the carriageway at least 2.75 m wide, which may be marked or unmarked with road markings and is intended for the movement of non-rail vehicles.
That is, the correct answer is "The lane to which the sign or traffic light, with which it is installed, applies," given that according to the definition of the Traffic Rules, plate 7.9 directly establishes to which specific traffic lane the relevant sign or traffic light applies.
This question concerns plate 7.9 "Traffic lane" from section 33 of the Traffic Rules of Ukraine. It is used together with a road sign or traffic light and helps to clearly understand to whom their requirement applies.
The meaning of this plate is that it limits the effect of the sign or traffic light signal placed above it to only one specific lane. That is, the requirement does not automatically apply to the entire direction of movement or all lanes, but only to where the plate points and above which it is placed.
In practice, it looks like this: if a sign (for example, a prohibition, mandatory direction, or informational sign) is installed above the right lane and plate 7.9 is placed under it, then the requirement of this sign must be followed by drivers moving in this right lane only. Drivers in adjacent lanes are not subject to such a sign if there is no separate sign or the same combination with a plate for them.
Similarly, plate 7.9 can clarify the effect of a traffic light: the signal may apply to a specific lane, not to all vehicles on the carriageway. This plate is used precisely for such clarification.
Therefore, the correct answer is "The lane to which the effect of the sign or traffic light with which it is installed applies," since plate 7.9 specifies that the requirement of the sign or traffic light signal applies only to the lane defined by it.
