33.3.29. Which of the shown road signs prohibits entry of all vehicles (except vehicles following established routes)?
UAЯкий із зображених дорожніх знаків забороняє в’їзд усіх транспортних засобів (крім транспортних засобів, що рухаються за встановленими маршрутами)?
This exam question from the Traffic Rules of Ukraine concerns road signs and road safety: the driver must be able to quickly recognize prohibitions specifically on entry, as well as understand the exceptions for route vehicles. Such situations often occur in cities near public transport lanes, at entrances to areas with restricted traffic, and in places where it is necessary to separate car and bus flows to reduce congestion and the risk of accidents.
The question tests knowledge of section 33 of the Traffic Rules, specifically 3 "Prohibitory signs," and the correct interpretation of sign 3.21 "No entry." It is important to distinguish between a "no entry" and a "no traffic" prohibition: sign 3.21 does not allow vehicles to enter the section of road before which it is installed, but its effect does not apply to vehicles operating on established routes (the definition of route vehicles is provided in the Traffic Rules terms). That is why, among the options, the correct one is image number 4, which corresponds to sign 3.21.
Analysis of the options helps to avoid common mistakes on the theoretical exam: sign 1, by its meaning, is more about a general prohibition of movement for everyone and does not focus on "entry" or the necessary exception; sign 2 belongs to warning signs and does not establish prohibitions; sign 3 is informational (related to the place to stop before a traffic light in case of a prohibitive signal) and does not regulate entry; sign 5 determines priority on a narrow section of road and does not restrict entry. In practice, the rule works as follows: entry is prohibited for private cars, but buses, trolleybuses, or other route vehicles traveling on their route are allowed to move within this section according to the traffic rules.
Clause 33.3 — 33 "Road signs", 3 "Prohibitory signs", sign 3.21 "No entry"
Sign 3.21 "No entry" — prohibits entry of all vehicles to the section of road where it is installed; the sign does not apply to vehicles operating on established routes.
Clause 1.10 (term "Route vehicles")
Route vehicles — public transport vehicles (buses, minibuses, trolleybuses, trams) that operate on established routes and have designated stopping places on the road.
Therefore, the correct answer is "Sign 4.", given that according to the definition in the Traffic Rules, sign 3.21 "No entry" prohibits entry of all vehicles, but does not apply to vehicles operating on established routes.
The key word in the question is "entry." That is, you need to find the sign that prohibits entering a certain section of the road, but at the same time makes an exception for vehicles operating on established routes (route vehicles).
Among the given options, sign 3.21 "No Entry" has this meaning. It is installed before a section of road where entry is prohibited for all vehicles. At the same time, this sign does not apply to vehicles operating on established routes, that is, buses, trolleybuses, and other route transport performing regular services.
The other signs in the image do not meet the requirements of the question. One of them may prohibit movement (not entry) for everyone, including route vehicles, so it is not suitable because it lacks the required exception. Another sign is a warning sign and does not impose any prohibition. Another informs about a stopping place before a traffic light when there is a prohibitive signal. There is also a sign that regulates the order of passing on a narrow section, and it is not related to entry prohibition.
In practice, sign 3.21 is often used when it is necessary to restrict the entry of regular cars onto a road or lane intended for route vehicles: entry is prohibited for private cars, but route transport is allowed to operate along its route.
Therefore, the correct answer is "Sign 4," as this is sign 3.21 "No Entry," which prohibits entry for all vehicles except those operating on established routes.
