This exam question from the Traffic Rules of Ukraine concerns road signs and traffic organization, which directly affects safety: the driver must be able to immediately understand where there is no oncoming traffic and how to correctly navigate the lanes and directions of movement. Such knowledge is critically important on city streets and when exiting adjacent territories, where a mistake can lead to driving 'against the flow' and a hazardous situation.
The question tests understanding of Section 33 of the Traffic Rules, specifically informational and direction signs, sign 5.5 'One-way road.' Its meaning in the Traffic Rules is unambiguous: it designates a road or a separated carriageway where vehicle movement across the entire width is carried out in only one direction. The correct answer essentially repeats the official description of sign 5.5, so for the theoretical exam it is enough to remember the key feature: all lanes operate in one direction, oncoming traffic is not provided for.
Other answer options describe different traffic organization modes. The statement about variable direction by lanes refers to reversible traffic, which is indicated by other signs and signals, and does not mean the road is entirely one-way. The option about the permitted direction of movement by lane refers to signs that regulate movement in a specific lane at an intersection or road section, but do not establish one-way movement for the entire carriageway. In practice, recognizing sign 5.5 helps to choose the correct trajectory, make turns, and avoid entering oncoming traffic, which is a typical mistake in exams and real traffic.
Clause 33.5 — 33 "Road Signs", 5 "Informational and Directional Signs", sign 5.5 "One-way Road"
Sign 5.5 "One-way Road" is used to indicate a road or a separated carriageway on which vehicle traffic across the entire width is carried out in only one direction.
Clause 1.10 (term "Carriageway")
Carriageway — an element of the road intended for the movement of non-rail vehicles.
That is, the correct answer is "A road or a separated carriageway on which vehicle traffic across the entire width is carried out in only one direction," given that according to the official definition, sign 5.5 directly indicates a road (or separated carriageway) with traffic in one direction across its entire width.
Sign 5.5 from section 33 of the Traffic Rules of Ukraine belongs to informational and guiding signs and informs the driver about a special traffic regime on this road. Its appearance means that one-way traffic is organized further on.
The key feature of this regime is that vehicles may move across the entire width of the carriageway in only one direction. That is, there is no oncoming traffic on this section, and all lanes (or the entire width of the carriageway, if lanes are not marked) operate in one direction.
In practice, it looks like this: you enter a street where the flow of cars moves only in one direction, and even if the road is wide enough, you will not see any legal oncoming traffic. This is exactly what distinguishes one-way traffic from a regular two-way road, where part of the width is allocated for oncoming vehicles.
Therefore, the correct answer is "A road or separated carriageway on which vehicle traffic is carried out in only one direction across the entire width," since sign 5.5 according to the Traffic Rules indicates one-way traffic with no oncoming flow across the entire width of the carriageway.
