UAЯка з табличок встановлюється із зображеним дорожнім знаком?
This exam question from the Traffic Rules of Ukraine tests the understanding of how warning road signs and their supplementary plates work in the context of road safety. In practice, such combinations are necessary so that the driver not only sees a general warning about a dangerous section, but also understands in advance what specific type of accident risk is typical at this location, and accordingly chooses the speed, distance, and trajectory of movement.
The question belongs to section 33 of the Traffic Rules, topic: road signs (warning) and supplementary plates to road signs. In particular, sign 1.39 "Accident-prone section (Other danger)" is used to indicate a place or section with a concentration of accidents together with plates 7.21.1–7.21.4 "Type of danger" (according to the Traffic Rules, 7.21.5 may also be used if it is provided). These plates specify the nature of the danger or the most likely type of accident that most often occurs on this stretch of road.
If we consider the answer options separately, choosing only one plate (1, 2, 3, or 4) would be correct only for a specific situation on site, but not as a general rule for the sign: each of the plates 7.21.1–7.21.4 is permissible and is installed depending on which type of danger needs to be indicated. Therefore, for the theoretical exam, it is important to remember the principle: all the listed "Type of danger" plates can be used with sign 1.39, and the specific one is determined by actual statistics and the nature of accidents on the section.
Clause 33.1.39 — 33 "Road Signs", 1 "Warning Signs", sign 1.39 "Accident-Prone Section (Other Danger)"
"Accident-Prone Section (Other Danger)". Warns about a section of the road (place) that is accident-prone (an area with a concentration of traffic accidents) or about another danger not covered by other warning signs; if this sign is installed to indicate a place (section) with a concentration of traffic accidents, plates 7.21.1–7.21.4 (7.21.5) "Type of Danger" are used together with it, depending on the nature of the danger/type of accident.
Clause 33.7.21.1 — 33 "Road Signs", 7 "Plates to Road Signs", plate 7.21.1 "Type of Danger"
"Type of Danger". Used with sign 1.39 "Accident-Prone Section (Other Danger)" and informs about the possible type of traffic accident (according to the image on the plate).
Clause 33.7.21.2 — 33 "Road Signs", 7 "Plates to Road Signs", plate 7.21.2 "Type of Danger"
"Type of Danger". Used with sign 1.39 "Accident-Prone Section (Other Danger)" and informs about the possible type of traffic accident (according to the image on the plate).
Clause 33.7.21.3 — 33 "Road Signs", 7 "Plates to Road Signs", plate 7.21.3 "Type of Danger"
"Type of Danger". Used with sign 1.39 "Accident-Prone Section (Other Danger)" and informs about the possible type of traffic accident (according to the image on the plate).
Clause 33.7.21.4 — 33 "Road Signs", 7 "Plates to Road Signs", plate 7.21.4 "Type of Danger"
"Type of Danger". Used with sign 1.39 "Accident-Prone Section (Other Danger)" and informs about the possible type of traffic accident (according to the image on the plate).
Clause 33.7.21.5 — 33 "Road Signs", 7 "Plates to Road Signs", plate 7.21.5 "Type of Danger"
"Type of Danger". Used with sign 1.39 "Accident-Prone Section (Other Danger)" and informs about the possible type of traffic accident (according to the image on the plate).
That is, the correct answer is "All of the above plates.", given that according to the definition in the Traffic Rules, plates 7.21.1–7.21.4 (as well as 7.21.5, if it is among the options) are "Type of Danger" plates and are used together with sign 1.39 to clarify the nature of the danger/likely type of accident at an accident-prone section.
Road sign 1.39 “Accident-prone section (other danger)” belongs to the warning signs. It informs the driver that there is a section of road ahead with an increased risk of traffic accidents or with a danger that cannot be clearly described by other standard warning signs. That is, the sign warns about a problem, but by itself does not explain what specific danger is most typical at this location.
That is why the Traffic Rules provide for the use of special plates from section 33 — 7.21.1–7.21.4 “Type of danger” with this sign. Their purpose is simple: to clarify which types of traffic accidents most often occur on this section. For example, in one place it may be collisions of vehicles, in another — hitting pedestrians or cyclists. When a driver sees such a plate under sign 1.39, they immediately understand what exactly to pay special attention to and how to choose a safe speed and distance.
Since all plates 7.21.1, 7.21.2, 7.21.3, and 7.21.4 are permissible according to the Traffic Rules (and are used depending on the specific nature of the danger) specifically together with sign 1.39, there is no single “correct plate number” for all cases in the question. The correct answer is that all the listed plates can be used — depending on which type of danger needs to be clarified at a particular location.
Therefore, the correct answer is “All of the above plates,” since plates 7.21.1–7.21.4 according to the Traffic Rules are installed together with sign 1.39 to clarify the type of danger (typical traffic accidents) at an accident-prone section.
