Clause 33.2.2 — 33 "Road Signs", 2 "Priority Signs", sign 2.2 "No Entry Without Stopping"

"It is prohibited to proceed without stopping before marking 1.12 (stop line), and if it is absent — before the sign. You must give way to vehicles moving on the intersecting road, and at a railway crossing — to a train (locomotive, railcar)."

This is the only one of the typical "intersection/crossing" signs that directly establishes the obligation of a complete stop (at an uncontrolled intersection or before a crossing), regardless of whether an obstacle is visible — the stop is required by the very nature of the sign.

Clause 34.1.12 — 34 "Road Markings", 1 "Horizontal Markings", marking 1.12 "Stop Line"

"1.12 (stop line) — indicates the place where the driver must stop in the presence of sign 2.2 or a prohibitive traffic light (controller) signal."

This clause is important for the answer, because sign 2.2 requires stopping specifically before 1.12, and if it is absent — before sign 2.2 itself.

Clause 16.3 — 16 "Passing Intersections"

"If it is necessary to give way to vehicles moving on the intersecting road, the driver must stop the vehicle before road marking 1.12 (stop line) or 1.13, at the traffic light so as to see its signals, and if they are absent — before the edge of the intersecting carriageway, without creating obstacles for pedestrians."

This clause explains the general rule of where exactly to stop at an intersection when a stop is required (in particular, in conjunction with sign 2.2 and/or marking 1.12).

Clause 33.2.1 — 33 "Road Signs", 2 "Priority Signs", sign 2.1 "Give Way"

"The driver must give way to vehicles moving on the main road, as well as vehicles moving on the intersecting road, unless otherwise provided by the rules for passing intersections."

This sign does not establish an unconditional obligation to "necessarily stop" — a stop is required only if necessary to give way (unlike sign 2.2).

Clause 33.5.69 — 33 "Road Signs", 5 "Information and Direction Signs", sign 5.69 "Stopping Place"

"Indicates the place where vehicles must stop before a traffic light or before a controlled intersection (road section) in case of a prohibitive signal from the traffic light (controller)."

Sign 5.69 by itself does not "require always stopping" — it only indicates the place where you must stop when a stop is already required by a signal (i.e., for controlled situations).

Clause 8.10 — 8 "Traffic Regulation"

"When a prohibitive signal is given by a traffic light (except a reversible one) or a controller, drivers must stop before road marking 1.12 (stop line), road sign 5.69 'Stopping Place', if they are absent — not closer than 10 m to the nearest rail before a railway crossing, before the traffic light, pedestrian crossing, and if they are also absent and in all other cases — before the intersecting carriageway, without creating obstacles for pedestrians."

This clause is added as related: it shows that in "controlled" situations, the obligation to stop arises from a prohibitive signal, and sign 5.69 only indicates the stopping place — unlike sign 2.2, which requires a stop at an uncontrolled intersection/crossing.

Thus, the correct answer is "Sign 1.", given that by the definition of the Traffic Rules, it is sign 2.2 "No Entry Without Stopping" that directly prohibits proceeding without stopping (before stop line 1.12 or, if absent, before the sign) at an uncontrolled intersection or before a railway crossing.

The key word in this question is “mandatory.” That is, we are interested in the sign that, by itself, at an uncontrolled intersection or before a railway crossing, directly obliges the driver to make a complete stop, regardless of whether other vehicles are visible or whether anyone needs to be given the right of way.

Sign 2.2 “No entry without stopping” (Section 33 of the Traffic Rules of Ukraine) is used precisely where a guaranteed stop is required: before uncontrolled intersections with limited visibility and before unregulated railway crossings. Its requirement is unambiguous: the driver must stop before the stop line (marking 1.12), and if there is no stop line — stop directly before the sign itself, and only after that continue driving, having ensured safety and yielded to those who have the right of way.

For comparison, sign 2.1 “Yield” does not require a constant mandatory stop. It obliges you to yield the right of way, and stopping is performed only if necessary, if it is otherwise impossible to safely let other vehicles pass. That is, the sign itself does not establish the rule “stop in any case.”

Another type of sign with the word “STOP” may indicate a stopping place at a controlled intersection (near a traffic light) and works together with a prohibitive signal: you stop when movement is prohibited by the traffic light, not always. At an uncontrolled intersection or unregulated crossing, this logic does not apply, because there is no signal that “activates” the obligation to stop.

Thus, the correct answer is “Sign 1,” since this is sign 2.2 “No entry without stopping,” which at an uncontrolled intersection or before a railway crossing requires a mandatory complete stop before the stop line, and if there is none — before the sign itself.
