33.3.74. Which vehicles are prohibited from driving in the area of effect of this road sign?
UAЯким транспортним засобам заборонено рух у зоні дії даного дорожнього знака?
This exam question from the Traffic Rules of Ukraine tests the understanding of prohibitory road signs and how they restrict the movement of certain categories of vehicles. Such restrictions are directly related to road safety: coupled units (vehicles with trailers) and towing require greater distance, road width, and create additional risks on narrow streets and complex road sections.
In content, this is the topic of Section 33 of the Traffic Rules, prohibitory sign 3.4 "Movement with a trailer is prohibited," as well as general provisions about the area of effect of prohibitory signs. It is important to read the sign literally: it does not apply to all cars, but specifically to trucks and tractors with trailers of any type, and separately prohibits the towing of motor vehicles. Therefore, the statement about the prohibition for "all cars with trailers" is incorrect, since passenger cars with a trailer are not subject to this prohibition.
The analysis of answer options in the theoretical exam comes down to the accuracy of the wording. The option about "trucks and tractors with trailers of any type" corresponds to the direct rule of the Traffic Rules, and the statement about the prohibition for those performing towing is also correct, because sign 3.4 prohibits towing regardless of the method (with a flexible or rigid coupling) and the type of vehicles. On the other hand, options that extend the prohibition to all cars with trailers are incorrect, since passenger cars with a trailer may move if there are no other restrictions. It is also important to remember the area of effect: as a general rule, it lasts from the location of the sign to the nearest intersection (or to the end of the populated area if there are no intersections), unless otherwise specified by additional plates.
Clause 33.3 — 33 "Road Signs", 3 "Prohibitory Signs", sign 3.4 "Movement with Trailer Prohibited"
Sign 3.4 "Movement with Trailer Prohibited" — prohibits the movement of trucks and tractors with trailers of any type, as well as the towing of motor vehicles.
Clause 33.3 — 33 "Road Signs", 3 "Prohibitory Signs" (general provisions about the area of effect of prohibitory signs)
The effect of prohibitory signs extends from the place of their installation to the nearest intersection beyond it, and in populated areas where there are no intersections — to the end of the populated area; the effect may be changed (specified) by supplementary plates to the road signs or by other signs that cancel/modify the restriction.
Clause 1.10 (term "Trailer")
Trailer — a vehicle designed to move as part of a combination with a motor vehicle.
Clause 1.10 (term "Towing")
Towing — the movement of one vehicle by another vehicle.
Clause 1.10 (term "Motor Vehicle")
Motor vehicle — a vehicle driven by an engine; this term applies to tractors, self-propelled machines and mechanisms, as well as trolleybuses.
That is, the correct answer is "Answers 2 and 3.", given that according to the definition in the Traffic Rules, sign 3.4 prohibits the movement specifically of trucks and tractors with trailers of any type and additionally prohibits any towing of motor vehicles, but does not prohibit the movement of passenger cars with a trailer.
In front of you is the prohibitory road sign 3.4 "No trailers allowed." It should be interpreted literally according to the description in the Traffic Rules: it is not aimed at all vehicles in general, but at specific categories of vehicles.
This sign prohibits the movement of trucks and tractors if they are driving with a trailer (or semi-trailer) of any type. That is, if a truck with a permitted maximum mass of over 3.5 tons is driving with a trailer, or a tractor is towing a trailer, their movement within the sign's zone will be a violation. This is exactly what one of the correct answer options covers.
It is also important to remember that this sign also prohibits towing of vehicles. For example, even if a passenger car is towing another car with a flexible or rigid coupling, this is considered towing and is prohibited within the sign's zone. That is why another correct answer option concerns towing.
At the same time, sign 3.4 does not prohibit the movement of passenger cars with trailers. Therefore, an answer like "all vehicles with trailers are prohibited from driving" is incorrect: a passenger car with a trailer may continue to drive if there are no other restrictions.
Thus, the correct answer is "Answers 2 and 3," since sign 3.4 prohibits the movement of trucks and tractors with trailers and prohibits any towing, but does not prohibit passenger cars from driving with a trailer.
