This exam question from the Traffic Rules of Ukraine concerns safety and traffic organization on multi-lane roads, where the driver must respond in a timely manner to changes in the number of lanes. Such situations directly affect the risk of side collisions and conflicts during lane changes, which is why they are often tested in the theoretical driving exam.
The question tests knowledge of Section 33 of the Traffic Rules of Ukraine, "Road Signs," specifically informational and directional signs, sign 5.21.2. Its meaning is that ahead, the lane designated for movement in the current direction ends (on the diagram, it is usually the left lane that "disappears"), and the carriageway for your direction narrows. The practical takeaway for the driver is simple: you need to prepare in advance to change lanes to the right so as not to end up in a section where further movement in this lane is no longer possible or it may become an oncoming lane.
When analyzing the answer options, the statement about a "lane joining from the right" describes a different road situation (when a lane is added), not when it ends, so it does not correspond to the meaning of 5.21.2. The option about the "end of an acceleration lane" may sound logical by association, but the official wording of the sign in the Traffic Rules does not specifically refer to an acceleration lane, so within the theoretical exam this is considered an error. A combined answer also becomes incorrect due to the presence of a false point; instead, the correct interpretation directly follows from the description of sign 5.21.2 in Section 33.
In real traffic, after such a warning, it is important to change lanes according to the rules: assess the situation in advance, signal, and when changing lanes, yield to vehicles moving in the lane you intend to enter (paragraph 10.3 of the Traffic Rules of Ukraine). This knowledge helps not only to answer the exam question but also to avoid common mistakes on roads with a variable number of lanes.
Clause 33.5.21.2 — 33 "Road Signs", 5 "Informational and Directional Signs", sign 5.21.2 "End of Additional Lane"
"End of Additional Lane." Informs about the end of a lane designated for movement in this direction.
Clause 10.3
When changing lanes, the driver must yield to vehicles moving in the same direction in the lane into which he intends to move.
That is, the correct answer is "About the end of the lane designated for movement in this direction," given that according to the definition of the Traffic Rules, sign 5.21.2 directly indicates the end of the lane in the same direction (and any further lane change must be performed in compliance with clause 10.3 regarding yielding when changing lanes).
Road sign 5.21.2 from section 33 of the Traffic Rules of Ukraine warns the driver about a change in the traffic arrangement ahead: one of the lanes in our direction is ending. From the image, it is clear that it is specifically the left lane that gradually “disappears,” and further on, the carriageway for movement in this direction narrows.
The practical meaning of this sign is as follows: if you are driving in the left lane, you need to prepare in advance to change to the right, because it will no longer be possible to continue driving in this lane. In real conditions, this often occurs in areas where the number of lanes changes or where the middle/left lane ceases to be a lane in your direction.
It is important not to confuse this sign with the situation of a lane “merging,” when a lane is added from the left or right. Here, on the contrary: a lane does not appear, but ends. Likewise, you should not substitute the meaning of the sign with the assumption of an “acceleration lane”: even if there are sometimes similar sections on the left, according to the Traffic Rules, this sign specifically informs about the end of a lane in this direction, not about an acceleration characteristic.
When you are changing lanes due to the end of a lane, act according to the general rules for changing lanes: assess the situation in advance, signal with your turn indicator, and yield to vehicles moving in the lane you intend to enter.
Thus, the correct answer is "About the end of the lane designated for movement in this direction," since sign 5.21.2 according to the Traffic Rules informs that the left lane in the same direction ahead is ending and further movement in this direction will take place with fewer lanes.
