33.1.15. Which of the following road signs warns about the beginning of a section of road with oncoming traffic after a one-way section?
UAЯкий з наведених дорожніх знаків попереджає про початок ділянки дороги із зустрічним рухом після одностороннього?
This exam question from the Traffic Rules of Ukraine tests the driver's ability to navigate road signs and to recognize changes in traffic organization in advance. This is critical for safety: after a section with one-way traffic, a driver may become "accustomed" to the absence of oncoming vehicles, so a warning about the appearance of oncoming traffic helps to avoid head-on collisions and mistakes when choosing a lane.
According to the traffic rules (section 33 "Road Signs", warning signs), the required sign must specifically warn about the beginning of two-way (oncoming) traffic after a one-way section. This function is performed by sign 1.26 "Two-way traffic", which is installed before the start of a dangerous section (typically 150–300 m outside populated areas and 50–100 m within populated areas). Therefore, the correct option in the list is the one with the warning sign "Two-way traffic" (in this ticket it is marked as sign 2), and it is logical to choose it in the theoretical exam.
The other options are only partially similar in meaning, but do not correspond to the key feature of "warning". For example, "End of one-way road" belongs to informational and indicative signs and only notifies about the end of the regime, without serving as a warning signal about oncoming traffic; "Priority over oncoming traffic" concerns priority on a narrow section, not the transition from one-way to two-way traffic; "End of reversible road" refers to reversible lanes; "Road narrowing" warns about a change in the width of the carriageway, but not about the appearance of oncoming traffic. In practice, this knowledge helps to reduce speed in advance, monitor markings and trajectory more carefully, and be ready for oncoming vehicles immediately after the change in traffic regime.
Clause 33.1 — 33 "Road Signs", 1 "Warning Signs"
Warning signs inform drivers about approaching a dangerous section of the road and the nature of the possible danger.
Clause 33.1.26 — 33 "Road Signs", 1 "Warning Signs", sign 1.26 "Two-way Traffic"
"Two-way Traffic". Installed at the beginning of a section of the road (carriageway) with oncoming traffic after a one-way section.
The sign is installed outside populated areas at a distance of 150–300 m, in populated areas — at a distance of 50–100 m before the start of the dangerous section. If necessary, the sign can be installed at another distance, which is indicated on plate 7.1.1 "Distance to the object".
Clause 33.5.6 — 33 "Road Signs", 5 "Information and Direction Signs", sign 5.6 "End of One-way Road"
"End of One-way Road". Used to indicate the end of a road or carriageway marked with sign 5.5 "One-way Road".
That is, the correct answer is "Sign 2.", considering that according to the definition of the Traffic Rules, sign 1.26 is a warning sign and is installed at the beginning of a section with oncoming (two-way) traffic after a one-way section.
The key word in the question is “warns.” Therefore, you need to look specifically for a warning road sign that informs the driver in advance about a change in traffic conditions ahead.
According to the Traffic Rules of Ukraine (section 33, sign 1.26), the “Two-way traffic” sign is installed before the beginning of a section where, after one-way traffic, oncoming traffic appears again. That is, a driver who is used to a one-way road should prepare in advance for the fact that on the next section, vehicles may be coming towards them. This is precisely the warning about the beginning of a section with oncoming traffic.
The other options from the list either only inform about the end of a certain regime (for example, the end of one-way traffic), or establish priority on a narrow section, or relate to other conditions (reversible traffic, narrowing). They do not perform the required function: to warn in advance that two-way traffic begins ahead after one-way traffic.
For example: you are driving on a street with one-way traffic and approach a place where traffic becomes two-way further on. It is sign 1.26 that will inform you in advance that oncoming vehicles may soon appear, and you need to choose your lane and driving trajectory more carefully.
Therefore, the correct answer is “Sign 2.” because it is the warning sign 1.26 “Two-way traffic,” which, according to the Traffic Rules, is installed at the beginning of a section with oncoming traffic after one-way traffic.
