In which of the following vehicles can you enter the road marked this way?

Explanation
Correct answer: In a tractor, if you are performing a cleaning job on the road.
The visible sign D-7 "Expressway" indicates entry onto a road where a traffic prohibition applies to, among others, agricultural tractors and slow-moving vehicles. However, the regulations permit an exception for vehicles carrying out cleaning, repair, or modernisation work on this road, which makes the indicated answer correct.
