33.1.72. Where is this road sign installed?
UAДе встановлюється даний дорожній знак?
This exam question focuses on road safety and the ability to correctly recognize warning road signs in order to reduce speed in advance and prepare for changes in road surface conditions. In the traffic rules, it is important not just to "recognize the picture," but to understand what specific danger it indicates, since road irregularities can worsen vehicle control, increase braking distance, and create a risk of vehicle damage.
The question tests knowledge of Section 33 of the Traffic Rules of Ukraine "Road Signs," specifically the warning sign 1.10 "Uneven Road," as well as the general requirements for the placement of warning signs (paragraph 33.1). According to the traffic rules, this sign is used before sections where there are irregularities in the carriageway in the form of undulations, bulges, or swelling; it is usually installed in advance: outside populated areas at a distance of 150–300 m, in populated areas at 50–100 m before the hazardous section, and other distances may be specified by plate 7.1.1 "Distance to the object." Such wording often appears on the theoretical exam, so it is useful to remember their connection specifically to sign 1.10.
The analysis of answer options helps to avoid typical mistakes on the theoretical exam: the option about potholes refers to another warning sign 1.12 "Pothole," so for 1.10 it is incorrect. The option about artificial humps for forced speed reduction corresponds more to the warning about "speed bumps" (artificial irregularities), not about surface deformations like waves or bulges. The option about raised or damaged shoulders describes a different danger (condition of the shoulder/work on it), so it is also not relevant for sign 1.10. It is precisely the difference between "uneven road" and "pothole" that this exam question on the traffic rules most often checks.
Clause 33.1 — 33 "Road Signs", 1 "Warning Signs" (general requirements for the installation of warning signs)
Warning signs inform drivers about approaching a dangerous section of the road and the nature of the danger. Signs are installed outside populated areas at a distance of 150–300 m, and within populated areas — at a distance of 50–100 m before the start of the dangerous section. If necessary, signs may be installed at another distance, which is indicated on plate 7.1.1.
Clause 33.1 — 33 "Road Signs", 1 "Warning Signs", sign 1.10 "Uneven Road"
1.10 "Uneven Road" — a section of road with unevenness of the carriageway — undulations, bumps, swellings.
Clause 33.7 — 33 "Road Signs", 7 "Plates to Road Signs", plate 7.1.1 "Distance to Object"
7.1.1 "Distance to Object" — indicates the distance from the sign to the beginning of the dangerous section, the place where the corresponding restriction is introduced, or to the object.
That is, the correct answer is "Before a section of road with unevenness of the carriageway – undulations, bumps, swellings.", given that according to the definition of the Traffic Rules, sign 1.10 "Uneven Road" specifically warns about such unevenness, and warning signs are installed before the start of the dangerous section (if necessary, the distance is specified by plate 7.1.1).
Road sign 1.10 from section 33 of the Traffic Rules of Ukraine belongs to the warning signs. Its purpose is to inform the driver in advance that there is a dangerous road feature ahead, due to which it is necessary to reduce speed and be prepared for changing driving conditions.
This sign is installed exactly where there are irregularities on the road surface that are noticeable while driving: undulations, swellings, or bulges. Such deformations can cause loss of comfort, worsen handling, increase braking distance, or create a risk of vehicle damage, so the driver must be warned before entering the problematic section.
It is important to distinguish this sign from sign 1.12 "Pothole": 1.10 warns not about potholes, but about general surface irregularities such as "waves" or "swellings." That is why the installation location is determined not before a single pothole, but before a section of road with such deformations.
As a warning sign, 1.10 is placed in advance of the start of the dangerous section: outside populated areas usually at a distance of 150–300 m, and in populated areas — 50–100 m. If it is necessary to warn at a different distance, it is specified with plate 7.1.1 "Distance to the object." This allows the driver to orient in time and prepare for the uneven section.
Thus, the correct answer is "Before a section of road with uneven pavement – undulations, swellings, bulges," since sign 1.10 according to the Traffic Rules warns about such irregularities and is installed in advance before the start of this dangerous section.
