33.1.12. Which of the depicted road signs is installed directly before a level crossing without a barrier with a single track?
UAЯкий із зображених дорожніх знаків встановлюється безпосередньо перед залізничним переїздом без шлагбаума з однією колією?
This is an exam question on the topic of road safety and the rules for crossing railway crossings. In driving practice, correctly recognizing warning signs near a crossing helps to reduce speed in advance, assess risks, and avoid dangerous situations, especially when the crossing is not equipped with a barrier and the responsibility for safe passage lies entirely with the driver.
The question tests knowledge of Section 33 of the Traffic Rules of Ukraine "Road Signs," Subsection 1 "Warning Signs," in particular the difference between signs 1.28–1.30 and the rules for their installation. An important nuance for the theoretical exam: one sign warns of an approaching crossing in advance (it is placed at a designated distance on the approach), while the other two mark the boundary of the crossing directly before the rails and additionally indicate the number of tracks.
The correct answer in this ticket is the option corresponding to sign 1.29 "Single-track railway": it is used directly before a railway crossing without a barrier with a single track and is installed directly at the hazardous section (if there is a crossing traffic light — on the same post with it, if not — no less than 20 m from the nearest rail). The option with the "more complex cross" corresponds to sign 1.30 for two or more tracks, and the triangular warning sign 1.28 only informs about the approach to a crossing without a barrier and is placed in advance, so it is not suitable when asked about the sign directly before a single-track crossing.
Clause 33.1.29 — 33 “Road Signs”, 1 “Warning Signs”, sign 1.29 “Single-track Railway”
Sign 1.29 “Single-track Railway” — indicates a railway crossing without a barrier across a single-track railway.
Clause 33.1.30 — 33 “Road Signs”, 1 “Warning Signs”, sign 1.30 “Multi-track Railway”
Sign 1.30 “Multi-track Railway” — indicates a railway crossing without a barrier across a railway with two or more tracks.
Brief application: the question checks the difference between 1.29 (one track) and 1.30 (two or more tracks) by the graphic depiction of the “cross”.
Clause 33.1.28 — 33 “Road Signs”, 1 “Warning Signs”, sign 1.28 “Railway Crossing without Barrier”
Sign 1.28 “Railway Crossing without Barrier” — warns of approaching a railway crossing not equipped with a barrier.
Clause 33.1 (33 “Road Signs”, 1 “Warning Signs” — rules for installing signs 1.28–1.30)
Sign 1.28 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.
Signs 1.29 and 1.30 are installed directly before the railway crossing; if the crossing is equipped with traffic lights — on the same post as the traffic light, and if not — at a distance of at least 20 m to the nearest rail.
That is, the correct answer is “Sign 2.”, considering that according to the definition of the Traffic Rules, sign 1.29 “Single-track Railway” is installed directly before a crossing without a barrier and indicates exactly one track.
In this question, you need to identify the sign that is placed not "in advance," but exactly at the boundary of the railway crossing when the crossing does not have a barrier and there is only one track.
According to Section 33 of the Traffic Rules of Ukraine, sign 1.29 is used to indicate a railway crossing without a barrier with a single track. It is installed directly before the crossing (in the hazardous area), that is, as close as possible to the place where the road intersects with the rails. If there is a crossing traffic light at the crossing, the sign is placed on the same pole as the traffic light; if there is no traffic light, the sign is installed no closer than 20 meters from the nearest rail.
Among the given options, sign number 2 is the cross-shaped sign with one "intersection," which corresponds to a single track. For comparison: the similar sign for two or more tracks has more "intersections" (this is a different sign), and the triangular warning sign about approaching a crossing without a barrier is installed in advance on the approach, not directly before the rails.
Therefore, the correct answer is "Sign 2," since it is sign 1.29, which is installed directly before a railway crossing without a barrier with a single track.
