Correct answer
C. Both at the back and front.
Explanation
In the photo there is a road tanker - a vehicle typically used to carry dangerous goods. The plates showing that a vehicle is carrying such goods should be placed at the rear and at the front - answer C.
The ADR Agreement requires a transport unit carrying dangerous goods to be marked with two rectangular orange plates, placed in a plane perpendicular to the vehicle's axis: one at the front and one at the rear of the combination. Thanks to this, emergency services recognise the danger no matter which side they approach the vehicle from, and in the event of a fire or leak they know how to put it out and how to secure the area. For tankers and bulk transport there is additional detailed marking: on both sides of the tank, plates with the hazard identification number and the UN number of the substance, and warning labels on both sides and at the rear of the vehicle. Marking on only one side (answers A and B) does not meet the requirements, and if the marking is missing, the law provides for a financial penalty and the stopping of the transport.
Legal basis: the ADR Agreement (section 5.3.2) and Art. 5 of the Act on the Carriage of Dangerous Goods
