The distance between the moving columns of agricultural tractors cannot be shorter than:

This question is about the minimum distance between moving columns of agricultural tractors. This distance must not be less than 200 m - answer C.

The Road Traffic Act specifies that the distance between moving columns must not be less than 500 m for columns of motor vehicles and 200 m for columns of other vehicles. By definition, an agricultural tractor is not a motor vehicle, so 200 m applies to columns of tractors. The gap between columns allows other drivers to overtake a column safely in stages and return to their lane. Distances of 50 m (answer A) and 100 m (answer B) are too small. Also note: no more than 5 vehicles may travel in a column of tractors, because they belong to the "other vehicles", and driving in a column does not release you from following the other rules.

Legal basis: Art. 32 para. 1 point 3, para. 2 and 4 and Art. 2 point 33 of the Road Traffic Act (Prawo o ruchu drogowym)
