33.1.5. Which of the depicted road signs is installed first when approaching a railway crossing?
UAЯкий із зображених дорожніх знаків встановлюється першим у разі наближення до залізничного переїзду?
This exam question from the Traffic Rules of Ukraine concerns warning road signs and traffic safety when approaching a railway crossing. Such signs are necessary so that the driver can assess the distance to the hazardous area in advance, have time to choose a safe speed, and avoid risky maneuvers such as overtaking or stopping near the crossing. In the theoretical exam, it is important to understand not only the appearance of the signs but also the logic of their sequential placement.
The question tests knowledge of Section 33 of the Traffic Rules, specifically warning signs 1.31.1–1.31.3 "Approaching a railway crossing" and their duplication on the left by sign 1.31.4. The essence is in the "countdown": the number of diagonal stripes indicates how far the crossing is. The more stripes, the greater the distance to the crossing, so the sign with the most stripes is installed first on approach (the farthest, approximately 150–300 m outside populated areas); then, closer options with fewer stripes are repeated (100–200 m and 50–100 m).
Among the answer options, the correct sign is the one that marks the beginning of this countdown, that is, the "farthest" warning (analogous to 1.31.1, and if necessary, it can be duplicated on the left as 1.31.4 with stripes slanting in the opposite direction). The other options are correct in content but are installed later, closer to the railway crossing, and therefore cannot be the first in the sequence of warnings.
Clause 33.1 — 33 “Road Signs”, 1 “Warning Signs”, sign 1.31.1 “Approaching a Railway Crossing”
Sign 1.31.1 is used outside populated areas to indicate the approach to a railway crossing (reverse distance countdown with stripes) and is installed first — at the greatest distance from the crossing (150–300 m). It is used together with signs 1.29 “Single-track Railway” or 1.30 “Multi-track Railway”.
Clause 33.1 — 33 “Road Signs”, 1 “Warning Signs”, signs 1.31.2 and 1.31.3 “Approaching a Railway Crossing”
Sign 1.31.2 is installed outside populated areas at a shorter distance to the crossing (100–200 m), and sign 1.31.3 — at an even shorter distance (50–100 m). The fewer stripes on the sign, the closer the railway crossing.
Clause 33.1 — 33 “Road Signs”, 1 “Warning Signs”, sign 1.31.4 “Approaching a Railway Crossing”
Sign 1.31.4 is the “left-sided” counterpart of sign 1.31.1 (the stripes are slanted in the opposite direction) and is installed on the left side of the road to duplicate the warning; it also corresponds to the greatest distance to the crossing (150–300 m) as the first in the reverse countdown sequence.
That is, the correct answer is “Sign 3.”, given that according to the definition in the Traffic Rules, the first sign (at the greatest distance of 150–300 m to the railway crossing) is sign 1.31.1 (and, if necessary, duplicated on the left by sign 1.31.4), followed by 1.31.2 and 1.31.3 placed closer.
When approaching a railway crossing outside a populated area, drivers are warned in advance by special signs with diagonal stripes. In Section 33 of the Traffic Rules of Ukraine, these signs are listed as 1.31.1 and 1.31.4, and they help to determine the distance to the crossing.
The logic of these signs is simple: the number of stripes indicates the countdown to the crossing. The more stripes there are, the farther away the crossing is, and vice versa—the fewer stripes, the closer the crossing. That is, the first sign encountered when approaching will always be the one with the greatest number of stripes, as it is placed the farthest from the crossing.
According to the rules, these warning signs are installed in advance, and the first of them is placed at the greatest distance (approximately 150–300 m from the crossing, depending on the permitted speed). Then, closer to the crossing, the next signs with fewer stripes are repeated. Similar signs may be duplicated on the left (variant 1.31.4), but the order of approach is determined precisely by the principle “more stripes—farther away.”
Therefore, the correct answer is "Sign 3," since the first warning sign installed is the one with the greatest number of diagonal stripes, which is placed the farthest from the railway crossing and marks the beginning of the distance countdown to it.
