Question without image
This is an exam question from the Traffic Rules of Ukraine concerning road safety during the transportation of dangerous goods. Such vehicles are a source of increased risk, so the traffic rules require that they be easily visible and clearly identifiable to other road users in advance, especially in dense traffic or limited visibility conditions.
The question tests knowledge of the section on cargo transportation, specifically the requirements of clause 22.6 of the Traffic Rules, as well as the identification signs from clause 30.3. According to these regulations, when transporting dangerous goods by road, the vehicle must move with its dipped headlights and rear position lights on and be marked with identification signs prescribed by the rules: an informational orange plate (orange-colored plate) and a danger sign (diamond with the hazard class symbol). It is the combination of these requirements that forms the correct logic for answering the theoretical exam.
When analyzing the options, just having the dipped headlights and position lights on without special marking does not provide clear information that dangerous goods are being transported, so this is insufficient. Separately installed identification signs are a mandatory part of the marking, but the Traffic Rules additionally require driving with the lights on, so the correct option must cover both conditions. An orange flashing beacon is not a general requirement specifically for dangerous goods: in clause 22.6, it refers to heavy/oversized vehicles and certain equipment, so including it as a mandatory marking for all dangerous goods transport is incorrect.
The practical significance of this topic is that proper marking and driving mode help other drivers keep their distance, avoid risky maneuvers, and orient themselves more quickly in the event of an accident or stop involving such a vehicle. For exam preparation, it is important to remember: the Traffic Rules of Ukraine emphasize both visibility (lights and position lights) and identification (orange plate and danger sign), which together provide a clear signal of increased danger on the road.
Clause 22.6
Vehicles engaged in the road transport of dangerous goods must drive with dipped headlights and rear position lamps on, and, in cases specified by special rules, with identification signs as provided for in clause 30.3 of these Rules. In addition, heavy and oversized vehicles, agricultural machinery with a width exceeding 2.6 m, must also have an orange flashing beacon (or beacons) switched on.
This clause directly indicates that when transporting dangerous goods, the vehicle must be marked with identification signs provided for in clause 30.3 of the Traffic Rules.
Clause 30.3 (identification signs: "Orange-colored plate", "Danger sign")
The following identification signs are installed on the respective vehicles:
f) "Orange-colored plate" — a rectangular orange plate with a reflective surface and a black border. The size of the sign, inscriptions of hazard identification numbers and dangerous goods, if required, and its placement on vehicles are determined by the European Agreement concerning the International Carriage of Dangerous Goods by Road;
g) "Danger sign" — an information plate in the shape of a diamond, displaying the danger sign. The image, size, and placement of the plates on vehicles are determined by the European Agreement concerning the International Carriage of Dangerous Goods by Road.
This clause specifies exactly which identification signs must be used to mark a vehicle transporting dangerous goods: an orange plate and a danger sign (diamond).
Therefore, the correct answer is "Answers 1 and 2," given that according to the Traffic Rules, vehicles transporting dangerous goods are marked with the identification signs "Orange-colored plate" and "Danger sign" (clauses 22.6 and 30.3).
When a vehicle is transporting dangerous goods, it is important for other road users to understand in advance that a source of increased danger is moving nearby. That is why the Traffic Rules require not only a specific driving mode but also clear external marking of such a vehicle.
Clause 22.6 of the Traffic Rules states that during the road transportation of dangerous goods, the vehicle must move with its dipped headlights and rear position lights on, and must also be marked with identification signs in cases defined by special rules. That is, special marking is used to identify such transportation.
The specific identification signs are explained in the list in clause 30.3 of the Traffic Rules. For dangerous goods, two key markings are used: an orange plate (an orange rectangle with a reflective surface) and a hazard sign in the form of a diamond with the corresponding symbol. In practice, this looks as follows: orange plates are installed at the front/rear of the truck or tanker, and diamond-shaped hazard class signs (for example, for flammable substances, etc.) may be placed on the sides—so that other drivers can properly assess the risk and act more cautiously.
Therefore, the correct answer is "Answers 1 and 2," since vehicles carrying dangerous goods are marked with an orange plate and a hazard sign (diamond) in accordance with the requirements of clauses 22.6 and 30.3 of the Traffic Rules.
