Show the correct answer
Correct answer
C. requires a permit.
Explanation
The question is about a vehicle combination made up of a lorry and two trailers. Driving such a combination requires a permit - answer C.
The Road Traffic Act states that a vehicle combination may consist of no more than 3 vehicles, but a combination pulled by a power-driven vehicle other than an agricultural tractor or a slow-moving vehicle may consist of no more than 2 vehicles. A lorry with two trailers is 3 vehicles, so it exceeds this limit, and driving a combination made up of more vehicles than permitted requires a category V permit. The obligation does not depend on the load - a permit is also needed when the trailers are empty (answers A and B). A combination of three vehicles is long, hard to overtake, and on bends it takes up the neighbouring lane, which is why the rules allow it only in exceptional cases.
Legal basis: Art. 62 para. 4 and para. 4b point 1 and Art. 64d of the Road Traffic Act (Prawo o ruchu drogowym)
