48.31. Which of the depicted road signs prohibits the movement of vehicles carrying dangerous goods?
UAЯкий із зображених дорожніх знаків забороняє рух транспортних засобів, що перевозять небезпечні вантажі?
This is an exam question on traffic rules regarding prohibitory road signs and the safety of transporting goods. In real-life situations, dangerous goods pose an increased risk to road users, which is why the Traffic Rules of Ukraine provide specific restrictions for vehicles carrying such substances, regardless of weight, vehicle type, or the presence of a trailer.
The question tests knowledge of Section 33 of the Traffic Rules of Ukraine, "Road Signs," group 3 "Prohibitory Signs," specifically sign 3.12, which concerns vehicles transporting dangerous goods and are marked with orange identification plates. For the theoretical exam, it is also important to understand the area of effect of this prohibition: it lasts from the place of installation to the nearest intersection, and in a populated area without intersections — to its end; exits from adjacent territories do not cancel the effect of the sign.
When comparing the options, signs 1 and 2 restrict movement only by weight parameters (total mass or axle load) and are not related to the class of cargo. Signs 4 and 5 impose restrictions based on the type of vehicle (trucks) or the presence of a trailer, but also do not specify what is being transported. Therefore, the correct option is the sign 3.12, as this is the only prohibition that directly concerns the transportation of dangerous goods in the Traffic Rules of Ukraine.
Clause 33.3 — 33 "Road Signs", 3 "Prohibitory Signs", sign 3.12 "Movement of vehicles carrying dangerous goods is prohibited"
"Movement of vehicles carrying dangerous goods is prohibited."
This prohibitory sign is used to prohibit the movement of vehicles transporting dangerous goods.
That is, the correct answer is "Sign 3.", since according to the definition of the Traffic Rules, it is sign 3.12 that prohibits the movement of vehicles carrying dangerous goods.
In this question, you need to find the sign that relates not to the weight or type of vehicle, but specifically to the transportation of dangerous goods. In the Traffic Rules of Ukraine, this is a separate prohibition provided in section 33, sign 3.12.
Signs 1 and 2 restrict movement based on weight parameters: one prohibits the movement of vehicles if their total mass exceeds the indicated value, and the other—if the permissible axle load is exceeded. That is, they are not related to the class of cargo and do not prohibit the transportation of dangerous substances as such.
Signs 4 and 5 are also not about dangerous goods: sign 4 prohibits the movement of trucks, and sign 5—the movement of vehicles with a trailer. These prohibitions depend on the type of vehicle or the presence of a trailer, but do not specify what is being transported.
The only sign that directly prohibits the movement of vehicles transporting dangerous goods is sign 3.12 (in the answer options, it is marked as sign 3). It is easily recognized by its specific feature related to dangerous goods: it is aimed at vehicles marked with orange identification plates. It is also important to remember that such a prohibition applies from the place where the sign is installed to the nearest intersection, and in a populated area without intersections—to its end.
Therefore, the correct answer is "Sign 3.", because it is the one (sign 3.12) that prohibits the movement of vehicles transporting dangerous goods.
