33.3.42. Which of the depicted road signs prohibits the movement of vehicles carrying explosive and flammable cargo?
UAЯкий із зображених дорожніх знаків забороняє рух транспортних засобів, що перевозять вибухові та легкозаймисті вантажі?
This exam question from the Traffic Rules of Ukraine tests the ability to recognize prohibitory road signs related to the transportation of dangerous goods. Such restrictions directly affect road safety, as explosive and flammable substances pose an increased risk to other road users, infrastructure, and the environment. In the theoretical exam, it is important not just to "recognize the picture," but to understand which specific category of transport the sign restricts.
The question belongs to section 33 of the Traffic Rules, topic 3 "Prohibitory signs," specifically sign 3.13. This sign is used to prohibit the movement of vehicles carrying explosive and flammable goods (such transports are usually marked with an identifying orange plate). It is also important to remember the standard area of effect for prohibitory signs: from the place of installation to the nearest intersection, and in populated areas without intersections — to the end of the populated area; at the same time, the effect is not interrupted by exits from adjacent territories.
Comparing the options helps to avoid common mistakes on the theoretical exam: sign 3.2 restricts the movement of all motor vehicles in general, but does not single out dangerous goods; sign 3.14 concerns another category — substances that pollute water; sign 3.15 introduces restrictions by weight and is used, for example, before bridges or structures with limited load capacity. Therefore, the correct option is the one that corresponds to sign 3.13, as it directly regulates the movement of vehicles carrying explosive and flammable goods.
Clause 33.3 — 33 "Road Signs", 3 "Prohibitory Signs", sign 3.13 "Movement of vehicles carrying explosive and flammable goods is prohibited"
The movement of vehicles with the identification sign "Orange-colored plate" carrying explosive and flammable goods is prohibited.
This clause of the Traffic Rules directly specifies which prohibitory sign is used to restrict the movement of vehicles carrying explosive and flammable goods.
That is, the correct answer is "Sign 3", given that according to the definition in the Traffic Rules, sign 3.13 directly prohibits the movement of vehicles transporting explosive and flammable goods.
In this question, you need to determine which specific prohibition sign applies to the transportation of explosive and flammable goods. All the proposed options belong to the category of prohibition signs, but each of them restricts movement based on different criteria.
The first sign (3.2) prohibits the movement of motor vehicles in general, that is, all vehicles powered by an engine. It does not specifically single out dangerous goods, so it is not suitable for this question.
The second sign (3.14) concerns vehicles transporting substances that can pollute water. This is a different category of dangerous goods, not directly related to explosive or flammable substances, so this is also not the correct option.
The third sign corresponds to sign 3.13 from section 33 of the Traffic Rules of Ukraine. It is this sign that prohibits the movement of vehicles transporting explosive and flammable goods (such transport is usually marked with an orange plate). That is, the sign directly indicates the required type of dangerous cargo, not the type of vehicle or its weight.
The fourth sign (3.15) introduces a restriction based on the weight of the vehicle, for example, before bridges or sections with limited load-bearing capacity. It is not related to the nature of the cargo, so it cannot be the correct answer.
Therefore, the correct answer is "Sign 3," since it is sign 3.13 that prohibits the movement of vehicles transporting explosive and flammable goods.
